Many are interested in the question at what temperature lice and nits die. Before you find the answer, you should understand what it is. Lice are a series of insects that make up about 3,000 non-flight species, three of which are classified as pathogens of parasitic diseases in humans. These are bloodsucking creatures that feed on human blood. They are most closely associated with humans, more than any other animals.
How do they arise?
The reason for this is the fact that lice live on the human body at all stages of its development. Lice are carriers of such dangerous diseases as, for example, typhus, which is widely known throughout the world. On the head of these insects are the eyes and antennae, which are the organs of the scent. The oral apparatus is prickly, sucking like, pulled in the middle of the head, placed in a special case. The secret of mucous membranes includes anticoagulants, which is very irritating to human skin, from which the itching of hair begins. In females, the posterior end of the abdomen is bifurcated, and in males it is rounded. Insects have claws on their paws, which gives the lice the ability to hold tight to human hair. Lice lay eggs called nits. They are pear-shaped, their size reaches 1 mm. More details about what temperature lice and nits die in the article.
What temperatures are they afraid of?
Parasites have adapted to the existence of the human body among the hair. These pests did not need to adapt to low temperatures or uncomfortable conditions. At temperatures from 20 to 38 degrees pests feed, lay nits and live for about 40 days.
If the thermometer creeps up or goes down, in this case they begin to feel discomfort. When a person with pediculosis gets ARVI, the temperature of his body will rise, and the parasites will prefer to move from the skin to the ends of the hair.
They are susceptible to sudden changes in the environment. If the temperature drops below 20 degrees, the parasite's vital processes are inhibited. The pest becomes apathetic, clings less to its hair and progresses more slowly, in the body of the female the eggs do not mature so rapidly.
If the temperature meter reaches 40 degrees, the louse stops laying nits.
Those who do not know at what temperature lice die during washing, you should know that you need to wash clothes at a temperature of at least 40 degrees.
Infection factors
People who adhere to personal hygiene often have a question about where their lice come from. By themselves, they can not appear, they can only be infected. The most common methods of infection:
- when traveling in public transport with large crowds,
- when visiting public places such as saunas bath pools,
- in gymnasiums, if the workouts are on rugs,
- when in contact with a person who suffers from pediculosis.
If there was exposure to one of these factors, then it is necessary to know at what temperature the head louse dies in order to get rid of the parasite as soon as possible.
And this is not the whole list where you can get this disease. Lice can pick up even in the fitting room in the store, if before that, the things that you tried on wore an infected person. It is often believed that carriers of lice are those people who do not lead the best way of life. These people include homeless people, drug addicts, alcoholics. As a rule, they do not take care of themselves and do not adhere to the rules of personal hygiene. Therefore, to avoid infection, it is better to stay away from such people. Of course, people who take care of themselves and their appearance, having discovered that they have lice, go into a deep panic. But, unfortunately, this disease can reach everyone.
At what temperature do they die?
Lice have a great capacity for distribution and reproduction. In contact with the human body, they secrete a sticky liquid, which contributes to their attachment to the skin. Having attached themselves to the skin, the females lay their eggs. Therefore, these insects are very difficult to stretch their own hands. And in this case it is worth knowing at what temperature the nits die. After all, 40 degrees is enough for lice, but nits need at least 60 degrees for death.
Ways of Transmission and Life Cycle
Lice are transmitted from person to person through infected items or through close contact. When it comes into contact with the skin, it feeds on blood and lymph. After this, the bite begins to itch. Females are able to lay from 5 to 15 eggs daily. She sticks them to her hair or to her underwear, and after 17 days little cubs appear.
Infestation of head lice in children is more common than in adults. Since children only come to know this world, they need physical contact with their peers. They have fewer psychological barriers for close communication. Children can easily put on someone else's clothes, as well as use someone else's towels and hairbrushes. For this reason, infection of children occurs much more often than adults. In this regard, it is necessary to be very attentive to the behavior of children, and at the first signs of infection, take urgent measures of prevention and treatment. It is very easy to determine if a person is infected with lice or not. For this you need to inspect the head, preferably in bright light. Often the first thing you can find eggs lice, nits. Very often they can be confused with dandruff. But in order to accurately determine whether this is so, you need to remove the nit from the hair and crush it between the nails. After that, you can hear the characteristic clicking sound.
Most accessible methods
Before you treat the living space from lice, wash at a temperature of 60 degrees pajamas, bed linen, hats, scarves, blouses, hair bands, sofa covers. Lice die at a temperature of 60 degrees and above. There will be no difficulties with cotton linen, and for items that cannot be washed at a considerable temperature, disinfect with a soap-kerosene emulsion (1: 1 ratio), put things in the prepared mixture for 20 minutes. You can use in the fight against parasites and freezer: put things in bales and place in the freezer for the day.
Boiling our friend
It is best to boil the laundry for 15 minutes. in a 2 percent sodium carbonate solution, a similar treatment for lice will be very effective. Hang things on the balcony and let direct sunlight disinfect objects throughout the week. After a fixed period iron iron all clothes (with steam), without missing a single fold - this will prevent the likelihood of parasites. After all, the temperature of the steam is much higher than the temperature of death of the nits. All hygiene items should also be decontaminated: immerse all scallops, combs for a couple of minutes in boiling water, as the louse can hide between the bristles.
Combing out
With regard to the treatment of pediculosis, there is no need to take either pills or injections. The treatment is carried out exclusively on the outside. The pharmacy has a large selection of ointments and shampoos, but these drugs do not protect against reinfection, so you should follow preventive measures. The most difficult process is getting rid of nits. Since the lice themselves die after using special tools, in the meantime, the eggs remain still alive, so you need to use combing tactics. To do this, you need to comb the nits with a comb with rare teeth over a period of two weeks. After this, it is necessary to apply conditioner on the hair with a thick ball after the washing of the head and begin combing. With the remnants of the air conditioner will remain on the comb and lice, so it must be periodically washed in hot water, since the temperature of the death of lice - at least 40 degrees. According to the scheme, combing is carried out four times every three days.
Chemical substances
After you have found lice, you need to start an active fight against these insects as soon as possible. There are many effective means by which you can get rid of these parasites. All these funds can be divided into two groups: chemical and folk. Chemicals are many types: powders, gels, ointments, creams, solvents, sprays and sticks. But among these funds, not all are comfortable to use.
For example, powders that contain small particles can easily get into the human body, and ointments and gels in most cases leave marks on the surfaces. The most suitable option is spray and aerosol. Since this is a finished product that can be used immediately. The effect of spraying allows you to literally handle all the surfaces in the house, as well as things and bedding with maximum efficiency.
Folk remedies
You can also use folk remedies, but often they are less effective than specialized drugs, but still in general are perfect for a comprehensive fight against parasites. Excellent herbs with expressive smells. Among them are such as wormwood and eucalyptus. They are used exclusively in dried form, laying them on the floor, carpets and pieces of furniture. This persistent scent scares away lice and nits. Also used peppermint, citrus fruit skin, which has a persistent odor, you can put garlic in rooms and furniture, as well as use vinegar for processing linen.
Fundamental rules
To get rid of lice and nits in the apartment, you should follow some important rules. First you need to prepare the room. Then thoroughly clean the floors to make the treatment more efficient. It will also help to immediately collect some of the pests with a brush or cloth. Then you need to collect all the personal items of the patient with pediculosis, including clothes and bedding, and wash them well in hot water, you can even boil them. At what temperature the water lice die is already known, so as not to leave the parasites any chance after washing, you need to iron all things with an iron. Particular importance should be given to the seams, because there may remain lice and nits.
You also need to carefully handle the places in which insects live or hide. These include plinths, upholstered furniture, carpets and soft toys. They need to be treated with great care. During disinfection and after it people should not be in the apartment (at least four hours). After the procedure it is necessary to ventilate the room. Approximately a week after the first treatment, a second one should be taken to get rid of the lice that hatched from previously laid eggs. All disinfection must be carried out in rubber gloves and a protective mask to avoid intoxication.
After such events, you can definitely get rid of lice and nits in the apartment, thereby fully securing yourself for a long time. But in order to avoid re-infection, it is imperative to adhere to personal hygiene, and also if possible not to contact with disadvantaged groups of the population. With these actions, you can actually protect yourself against lice, perhaps forever.
What temperature do lice tolerate?
All insect parasites that live at the expense of humans can exist only at a certain temperature, their body is not adapted to survive in other conditions. This is easy to explain: for many centuries they have been parasitic on the human body, and they simply have not developed resistance to cold or heat. You can use this feature of lice in order to fight them. At what temperature is the vital activity of lice inhibited, and what is destructive for these insects?
Critical temperature for lice: from –5 to +40 degrees, but depending on external conditions and on the developmental stage at which the insect parasite is located, this interval can vary both upwards and downwards. The insect does not always die, this requires critical temperatures, and under milder, although unfavorable conditions, the nits remain viable for up to six months. They seem to be preserved, and when the temperature of the air around them becomes suitable for them, they continue their development again.
The effect of high temperatures on lice
Lice do not like high temperatures, if the heat reaches 40 degrees, the female loses the ability to reproduce, the eggs no longer mature in her body. If the temperature rises even more, the embryo in the already laid nits slows down in its development, and at a temperature above 60 degrees its death occurs.
Details on the effect of high temperature on lice:
- When the temperature reaches 40–45 ° C - the female stops laying eggs and loses the ability to reproduce.
- At a temperature of 45–50 ° C, the parasites themselves and their larvae can live from 30 minutes to several hours.
- The temperature reaches 50–55 ° C - lice die within a few minutes, and the development of the larvae stops.
- 55–60 ° C– almost instantly insects die, and although their eggs remain viable, the larvae do not develop (if the temperature drops to a comfortable one, the development of nits will continue).
- The temperature is 60 ° C and higher - the insects themselves die instantly and their larvae too.
It can be concluded that nits are more resistant to high temperatures, and this is true. This is due to their survivability by the presence of a very hard shell, which plays the role of a protective shell. In the adult insect, the chitinous cover is soft, and it does not protect them so well from the effects of heat.
At high humidity, the overheating of the body of the insect occurs faster, so it dies at a lower temperature. The above temperature parameters were calculated for an air humidity of about 70%.
The effect of low temperatures on lice
Cold lice fear no less than the heat. When an insect turns out to be at zero temperature, it will have a condition similar to shock. You can compare it with hibernation: your louse does not feed, does not reproduce, practically does not move, the development of embryos in the eggs and the larvae themselves stop.
But all this does not mean that for the death of lice and nits enough 0 degrees Celsius. Of course, if the insects are left at this temperature for a long time, they will not be able to exist and will die as a result. But they are experiencing a short-term decrease in the ambient temperature quite successfully, and after warming they resume their life cycle.
So how does minus temperature affect lice and their larvae?
- When the temperature drops to 0–5 ° C, the lice stop, stop feeding and multiply, embryos stop developing in their eggs.
- From -5 to -15 ° C the death of lice occurs within a few minutes, while the nits do not develop, but remain viable. In this state, they can spend a few days, and when the temperature rises around, they will continue to develop.
- At temperatures of -15 to -20 ° C, both lice and their larvae die within a minute.
- -20 ° C - nits die instantly.
These temperatures are indicated for an air humidity of 70%. If the humidity is higher, the lice and larvae of these parasites die faster.
But everything is not so simple, and to win lice with the help of the cold is very problematic. The fact is that they usually hide on the human body, in his hair, clothes, the temperature there is always positive, which means that it is quite acceptable for the development of these insects. One may walk without caps or swim in the hole, it would not harm louse, but the person himself may well get sick.
Ways to fight lice with the help of cold exist, but are used to kill insects that are on clothes, underwear. With parasites, which are located on the human body, will have to fight somehow differently.
We kill lice with temperature
Methods of temperature exposure can be very effective in the fight against parasites, in addition, they have several important advantages:
- Do not harm health. Unlike chemicals that get on the skin of people, in their lungs along with inhaled air, the destruction of lice with the help of heat and cold can not cause any harm to the human body.
- Do not require financial costs. Modern drugs to combat skin parasites are not so cheap, and often the more effective the tool, the more expensive it is. Fighting lice with heat and cold can be completely free.
- Convenient to use and effective. It is quite easy to get rid of lice and nits, creating an uncomfortable temperature for them, and if you use the right temperature, you can be sure that insects will die.
The choice of method of exposure and temperature depends on where the parasites are located, as well as on the stage of their development.
Freezing lice and nits
Exposure to cold is particularly effective in the fight against laundry lice. This method is called freezing, and it can be carried out in different ways.
In winter, collect all laundry contaminated with lice and their larvae, and hang it in the cold. It must be at least -20 ° C. Lingerie should hang in the cold for several days, while all lice are guaranteed to die, but the nits can survive, so this treatment should be carried out in 2 or even 3 stages with a break of several days.
Put all the contaminated items in the bag and place them in the freezer. Select the quick freeze mode in it, and leave it for a few hours. Lice and their eggs will die from such exposure.
If it is not cold outside (warmer than -15 ° C), the lice will not die. They just stop eating and breeding, but can live like this for about 2 weeks.
Unfortunately, for body lice to use the cold does not work: rather the man himself will die from the cold than the lice that parasitize on it. Therefore, to combat body lice, on the contrary, high temperatures are used.
Heat shattering lice
With the help of high temperatures, you can get rid of laundry lice, and from those parasites that are directly on the human body. The hot air, which still does not burn the skin of people, turns out to be fatal to lice and nits. To get rid of parasites used several methods associated with exposure to high temperature.
Remove parasites from clothes
1 way
Put all the clothes contaminated with lice and nits in the tank, pour water and boil for at least an hour. It is necessary that the laundry is warmed up completely, all its folds, stitches.
2 way
All underwear must be folded into the machine and washed in very hot water. It is necessary that the water temperature was not lower than +60 ° C. It is better to choose a boiling program.
3 way
Carefully iron the clothes with a hot iron. It should be ironed from two sides, without missing a single section, and especially try to warm up the places where the fabric is folded in several layers: bends, pockets, collars.
It is better to combine all these methods so that not a single insect or its larva survives, otherwise it will not be possible to completely get rid of lice, and the fight against them may be delayed for a long time.
How to get rid of body lice with high temperatures
Lice out of the hair is not so easy to bring, although a lot of strong agents are being sold against these parasites. It often happens that a person fights lice, uses different drugs, and insects appear again and again. Then the folk remedies are used, but they do not always cope.
To get rid of lice and nits, you should start to deal with them immediately after you have found them, and try to carry out a comprehensive treatment: hair, clothes, bed linen.
You can use strong chemicals, but if they are contraindicated to you or do not help, you should use other methods.
One of the old, but effective methods of combating head lice is combing lice and nits. For this special combs are sold. Of course, it will not be possible to completely remove all parasites at a time. To cure head lice, you should brush your lice and their larvae regularly, every day, for several days - usually it takes about 7 to 10 procedures. But if you use this method in conjunction with heating the hair (for example, using a hair dryer), getting rid of parasites is much easier and faster.
The fact is that when lice are combed out with a comb, it is very easy to skip them, especially since insects move rather than sit and wait for their destruction. But with a strong temperature increase, the lice become inactive, they no longer cling to the hair, so combing them out is easy.
In order for the insect to cease to be active, the temperature is only about +45 ° C, and if the humidity of the air is very high, then even less. Of course, at such a temperature, the lice will not die, but it will be much easier to cope with them.
Lice in the hair with heat
There is a special apparatus, it is used mainly by American parasitologists, this is the so-called medical dryer. For the first time this device was created in the UK, when scientists found that lice is less viable for people in southern countries because they are oppressed by the scorching sunlight. Now this device is used mainly to combat insect parasites in children. The child is put in a chair, include a medical dryer and carefully treat his head with warm air. After that, immobilized lice and nits combed by hand.
The effect of heat is based on the method of getting rid of lice with a home hair dryer. To use it, you will need a hair dryer with a diffuser attachment, a frequent comb to brush the lice out of your hair, and someone to help you with the procedure.
How to remove lice with hot air:
- Wash your head with very warm (almost hot) water.
- Turn on the hair dryer on the mode of strong heating and begin to heat the hair evenly. The diffuser will help you with this.
- Heat the hair should be within half an hour, but household hair dryers are not designed for such a long work. Therefore, it is better to take two hair dryers and alternate them, or after 10 minutes of work, turn off the device to give it a little rest. Breaks for more than 3 minutes should not be done, because otherwise the lice will “revive” and begin to move.
- After heating, proceed to combing lice from the hair. This should be done methodically, centimeter by centimeter clearing the head of lice and their larvae. For an hour, the lice will remain still, so try to have time to comb them during this time.
Choose a temperature that is tolerable for you, otherwise you risk just ruining your hair and getting a scalp burn.
In fact, pediculosis is now very common, it is especially common in children's groups, and lice are transferred from children to their parents and other family members. It is very important to start fighting insects in time and act correctly, and then you will quickly get rid of them.
At what temperature do parasites die?
The fight against lice must be approached comprehensively, that is, to use several proven and effective ways. In pharmacies in a large assortment and price range, various drugs are presented that can help bring out lice.
When the process is not too running, it is permissible to use folk remedies. In any case, you need to know at what temperature lice and nits die to get rid of them as quickly as possible.
Lice are quite unpretentious insects, but they can fully exist and reproduce only within a certain temperature scale. At rates below -13 ° C and above + 54 ° C, lice and nits die almost immediately, within five minutes. It should be borne in mind that these temperature frames are approximate:
- if the atmospheric humidity is high, then the critical temperature for lice death is already below + 54 ° С,
- if the temperature is + 42–44 ° С, the louse weakens considerably. In this case, the parasites are combed with a special comb from pediculosis.
Important! Presented information should not be taken literally. And run out into the cold with no head covered or take a steam bath in the sauna.
Temperature, which is fatal, for lice and nits, It is mainly used in the fight against body lice, since their habitat is clothing, bed linen, etc. Linen is hung out at a low temperature or simply with steam.
At what temperature do lice eggs die?
Eggs laid by lice are called nits. They are quite tolerant to temperature extremes. This fact must be taken into account in the integrated control of parasites, since lice can be removed, and nits will remain, and the problem will not be completely eliminated. Nits die if the temperature:
These conditions apply specifically to laundry lice. Contaminated clothing, underwear is better to boil or hang in the cold. Adults cannot do for a long time without food, but the larvae can, and when acceptable conditions are restored, they will hatch successfully. In addition, the nits are very securely attached to the surface of the hair tissue. After appropriate treatment, they must be removed, combed, cleaned.
Important! For the prevention and control of body lice, clothes and underwear in winter are hung outside when the frost is -20 ° C for a long time.
For the sake of infection by lice, you can not use someone else's comb, towel, hat, etc.
To destroy head or pubic lice, it is better to use pharmaceuticals.
Knowing at what temperature conditions lice and nits die, you can successfully, and most importantly, effectively and quickly deal with them. Observe personal hygiene.
Ways to fight insects
Knowing the temperature at which the lice die, you can easily neutralize them, but at the same time do not forget about nits. Observing certain temperature frames is easy to deal with.
Freezing of clothes and clothes is carried out in the following ways:
- freeze outside when the frost is below 20 ° C
- contaminated items, put in packages and use instant freezing.
When using high temperatures, other methods are used:
- With the help of a hot stream of air from a hair dryer, the body part is treated, then the lice and nits are mechanically selected,
- washing in the washing machine at high temperatures, not less than + 60 ° С,
- ironing linen, paying special attention to the seams and folds,
- boiling things for one hour.
The given methods of exposure are very effective and safe if you take precautions. Despite the fact that it will take some time and effort, the result will be justified.
The effect of temperature on lice breeding
Lice are fairly prolific insects, but temperature conditions also affect their rate of reproduction. When the temperature drops just below + 22 ° C and rises above + 40 ° C, the larvae feel uncomfortable, their development stops, and the adults weaken and stop biting their host. The development of nits is also slowed down, the process of their growing up is suspended.
Under normal conditions, suitable for the safe development of insects, the female of reproductive age lays 140 eggs. Maturation of nits is approximately 16 to 18 days. When the temperature drops, this period increases from 23 to 24 days. A comfortable temperature for parasites is from + 30 ° C to 32 ° C.
When the temperature rises above normal, about + 37 ° C, + 38 ° C, the lice cease to multiply, but if it grows even higher, the parasites will die.
Given the effect of temperature on the reproduction of lice, we can conclude:
- with a decrease - lice become unviable, the larvae die from hunger, as they stop feeding,
- with the increase - just die.
Pediculosis and ambient temperature
Lice are very sensitive to temperature parameters. Evolutionarily, they did not need to adapt to different temperatures, since they were always on the human body in a constant thermal interval.
Even with a slight increase or decrease in degrees, the parasites begin to experience discomfort.
Optimum for different types of lice:
Head parasites react very actively to changes in temperature. With +20 females stop laying, and the development of already hatched larvae stops.
With all their sensitivity to high temperature, individuals belonging to the head species never leave the temperature of the sick. In contrast, the clothes lice crawl away from patients with a high fever and thus spread dangerous infections: typhoid, Volyn fever.
The lower the temperature, the more parasite is able to starve. At 25-30 degrees, insects can not eat for 2-3 days, and at + 10 they can do without food for 7 days without any problems.
Conditions under which nits die
Lice eggs are more resistant to temperature fluctuations. They survive when adult insects already die.
The embryo in the egg is protected by a dense shell, therefore it is quite resistant to external conditions. Lice eggs remain viable even after a 10-minute dive into kerosene or ether.
State of nits at different temperatures:
- 50 degrees - survive 30 minutes
- 54 degrees - can withstand heat for 30 minutes
- below 20 degrees and above 45 degrees - cease to develop.
Effect on reproduction rate
The temperature determines the intensity of the egg-laying and the rate of development of the parasites:
- + 30-32 degrees - the best interval for reproduction of lice, the length of the reproductive cycle at this temperature is 16-17 days,
- + 34- 35 degrees - the reproductive cycle begins to lengthen.
Under optimal conditions, the stage “from nits to nits” passes in 17 days. Cooling and warming stretch this period:
- + 25 degrees - the period "from nits to nits" is 35 days,
- + 38 degrees - reproduction stops.
The influence of the environment on the larvae
At + 21 and + 41 degrees, the larvae stop feeding, their development stops. They do not die. When the normal temperature is restored, they will become sexually mature - imago.
Are wares afraid of frost?
Things of patients with any type of lice can be frozen. At a temperature of -40 degrees lice instantly die. For reliability, all the clothes of the patient are hung out in the cold for a week.
In order for the nits to die, and not just the lice, it is important that the temperature all this time be no higher than -20.
Effect of cold on lice:
- -5 - parasites freeze, cease to multiply and feed, embryos in eggs stop developing,
- -5- -15 adults die in a few minutes, nits remain viable for several days,
- -20 and below - the rapid death of lice and nits.
Lice and nits can only be frozen from fabrics and objects. It is impossible to freeze parasites directly from the body. It is useless, trying to remove the head lice, to walk in the cold without a hat in the hope that the insects will die.
Forensic scientists know that lice leave a corpse only when it cools down to + 20 degrees.If the body remains warm (36-37 degrees), the lice will survive, no matter how the person is exposed to cold.
Methods of dealing with parasites using high temperatures
For many years I have been studying intestinal problems, in particular salmonellosis. It is terrible when people do not know the true cause of their diseases. It turns out that the whole thing in the bacteria Helicobacter Pylori.
These bacteria are able to live and reproduce not only in the intestine, but also in the stomach. Being introduced deep into its walls, the larvae are distributed through the whole body by the blood flow, getting into the heart, liver, and even into the brain.
Today we will talk about the Notoxin natural product, which turned out to be incredibly effective in treating salmonellosis, as well as participating in the federal program “Healthy Nation”, thanks to which the product can get for FREE when applying until November 27th.
With head lice and phthiriasis, objects that come into contact with the patient's hair — combs, towels, hairpins, hats, and linen — are dipped for 30 seconds into the water heated to +60 degrees.
The desired fabric processing temperature can be obtained in an automatic washing machine, setting it to the appropriate mode. Or enter the old fashioned way - put the clothes in the heated water on the stove in a bucket or tank.
Body lice most of the time is spent in clothes, being on the body of the owner just a few minutes a day. They also lay eggs on clothes. For disinfection, bedding and clothes of the patient are washed separately from other things and ironed with steam using an iron.
It is not rational to try to kill nits and lice with a curling iron or hair straightener. Live nits are very close to the scalp - the first 2 cm of hair.
The video is dedicated to mechanical methods of lice exposure, including temperature control methods:
Eggs located farther from the skin are guaranteed to fall under the temperature effect of the electrical device, but they are already empty - there are no embryos in them. Attempts to burn the parasites with an iron, curling hair dryer or hair dryer will lead to scalp burns and hair damage.
The easiest way to fight physical methods with ward parasites. The clothes on which they are present can be boiled. When processing clothes in boiling water (100 degrees Celsius), the parasites have no chance to survive.
Heat treatment is preferable to removing lice from hunger. If contaminated clothing is packaged in a waterproof package, adults will die of starvation. Nits just fall into a state of hibernation and survive.
When a person puts on a thing, the nits will warm up, the larvae will come out of them and the disease will begin in a new way. Therefore, when worn lice clothes and bed must be treated with chemicals or high (low) temperature.
Sometimes it is not necessary to kill the parasites - it is enough just to immobilize them. At 42 degrees, adults weaken to such an extent that it becomes easy to comb or shake them off. This technique is used before combing parasites with a special comb.
Charismatic doctor Ekaterina Makarova about pediculosis:
In America, developed an electrical device for hot blowing head and pubic lice. The device blows only the affected part of the body. Airflow is conducted at a temperature of about 50 degrees.
For a person, this procedure is palpable, but painless. Lice do not die, but simply lose the ability to move and can no longer be held by the hair. A short hair blowing immobilizes parasites, which can then be shaken off or combed out.
Such hair dryers are difficult to find on sale, but you can use the method itself. To do this, before the combs lice, the hair is washed in water heated to 55 degrees, and then dried with the usual drying with the maximum temperature set.
Parasites need to be combed over a bath or a sheet of white paper. Then they are collected and burned, as they did not die, but simply numb and retained the ability to infect.
When there is a question about how to get rid of lice, any method is good. Temperature treatment is more effective when combined with chemicals. It is better to clean the body and head from parasites, using special shampoos for lice with insecticides or fatty oils.
Personal things are more convenient to warm or freeze - in this case they will not remain stains and odor of toxic chemicals.
The effect of temperature on nits, lice
Based on the fact that lice are blood-sucking, often the question arises whether lice are afraid of temperature extremes. In order for lice to develop and multiply normally, they need constant access to food, blood-sucking parasites feed at least 5 times a day, the air and the optimum temperature. Since insects are on the surface of the skin, food is available to them at any time. And to change the temperature regime a person can.
If you create unacceptable conditions for the parasites, they will soon die. To do this, a cardinal increase or decrease in temperature should be made.
A temperature that satisfies lice ranges from minus 3 to plus 40 degrees. The most comfortable conditions under which parasites continue to feed, lay eggs, live for about 40 days, are created from plus 20 to 38 degrees Celsius. At lower rates, the bloodsucking experience discomfort.
Note, if a person infected with pediculosis suffers from acute respiratory viral infections with a rise in temperature, the insects move from the skin to the very tip of the hair. This increases the spread of the disease.
The lice larva is protected by a durable sheath, which makes it more resistant to temperature extremes. Nit can survive even if its environment warms up to 50 degrees. However, it is susceptible to low thermometer performance. At subzero temperatures, the larvae cease to develop.
At what temperature do lice and nits die?
Lice are susceptible to extreme temperature extremes. When the environment is observed plus 20 degrees, then their processes slow down. Lice become sluggish, loosely attached to the hair, their reproduction slows down. The female becomes less fertile. If the thermometer reaches plus 40, it completely stops putting off the nits.
Effect of cold
Some people, knowing at what temperature the bloodsucking die, think that it will be enough to walk without a hat in the winter time to get rid of them. However, this method does not work. Because lice live on the skin of a person who cannot have a temperature with a minus sign.
The hair part of the head maintains satisfactory conditions for the life of the parasites. Faster people will freeze himself, than lice finish the process of reproduction.
Interesting fact. Nits during the week can go without a human body. If comfortable conditions are created for the larva during this time period, then it will easily become an adult and will be ready for reproduction. How lice multiply, the speed of development, you will find on our website.
Low thermometer readings affect parasites as follows:
- at minus 5 lice do not breed, do not feed. In nits, development slows down
- at minus 15 adult mortality occurs. However, the activity of the larvae continues
- at minus 20 Nits die.
If the thermometer shows minus 20, then 45 minutes will be enough for parasites to die. If the temperature reaches minus 17, then they will need at least 2 hours.
Heat effect
No less cold lice are afraid of high temperatures. If the parasite is protected from frost by the heat and hair of an infected person, then it tries to get away from excessive heat from the skin.
An increase in the temperature of the surrounding reality has a negative effect on the parasite as follows:
- at plus 40 degrees the female stops the breeding process,
- from 45 to 60 adult parasites are dying. However, the larvae continue to develop,
- at plus 60 and above Nits are dying.
Lice have a sharper response to high thermometer rates. They have the destruction of internal organs, leading to death.
Temperature control methods
Knowing at what temperature lice and their larvae die, it is possible to wage an effective struggle with them in specialized ways.
To weaken the parasites at home used a hair dryer. It is noticed that when properly applied, it can kill up to 96% of insects. To do this, you need to wash your hair as hot as possible.
Then for a long time should be dried with a hairdryer, bringing the device closer to the skin. Temperature conditions of the dryer should be at maximum performance.
To carry out this treatment, a diffuser is worn on the hairdryer. This nozzle is included in the standard set. The usual procedure time is 10 minutes. Then you need a break.
As home hair dryers are not adapted for work in a long mode. After that, the thermal effect on lice is carried out twice more.
Attention! Blow-drying does not destroy head lice, but they become lethargic, they cannot hold on to their hair, they literally get enough sleep. As a result, lice are easily combed out from the curls. And they will be weakened within an hour.
Immediately after the procedure, you need to comb the hair with a special comb. To achieve the desired result, Hair treatment should be carried out for at least a week. This is due to the fact that nits hatch in a period of 7 to 10 days.
Knowing the sensitivity of insects to temperature extremes, many people have a natural question whether nits can be killed with an iron to straighten hair. This method has found a worthy place to combat head lice.
Ironing against lice also affects juveniles and parasite eggs. Due to its effect, the larvae lose their protective sheath, sticky components, with the help of which they stick to the hair.
To get the maximum effect you need:
- Wash your hair with shampoo.
- Split hair into small strands.
- In order not to harm the curls, you can use thermoprotective drugs.
- Processing should begin with the neck.
- Slowly hold the iron along the entire length of the hair, to the very tips.
- Next, carry out combing with a bloodsucking comb.
Ironing for hair against lice and nits should not be carried out for more than 2 seconds. Since too long contact can seriously damage the structure of the curls.
Also for the treatment of pediculosis, you can go to the bath. This procedure strengthens the general condition of the person. And blood-sucking parasites die in these conditions. Lice and bath are incompatible things. However, you should remember about hygienic measures.
Since insect eggs can go without a person for a long time, they can endure extreme heat for a short period of time.
Lice and nits can be killed only in a well-heated bath, where the air temperature reaches plus 80 degrees. Nits retain their vital functions up to plus 60. When accepting this procedure, it should be remembered that It is necessary not only to bathe, but also to water the hair with the most hot water.
Attention! After the bath should be treated with a hair dryer, comb the parasites with a comb. It is noticed that after 3 such sessions not a single blood-sucking remains. How to quickly comb out lice and nits from long hair, read on our website.
Using an iron or steam cleaner is an excellent alternative to boiling water. This method is used both on linen, and on soft toys, furniture, blankets.
Processing should be done with the maximum allowable temperatures. During ironing it is important not only to pay attention to the front side of the product. Lingerie needs to be turned inside out, close attention is paid to the seams.
It is possible to destroy body lice only by cold exposure without harming human health. To cause their death, you should hang the product in the cold for 2 days.
Under these conditions, lice and their larvae die, as the thermometer values below 20 ° C are critical even for nits. Besides, A large percentage of air humidity is also considered an indicator for the imminent death of parasites.
After the necessary time, you need to remove the brush of frozen parasites. After returning home, provided that this allows the product, a hot iron or steam treatment of all internal joints should be carried out. Since this is where bloodsucking suckers prefer to hide.
Cold treatment for lice and nits can also be done in a different way. To do this, should be things that were in use in an infected person, put in a plastic bag. Place in the freezer for a few hours.
Under similar conditions, the death of insects occurs within 3-4 hours. Then it remains to remove them from the seams, folds. After that, it is recommended to wash clothes, ironed with a hot iron.
Advantages and disadvantages
Temperature exposure to lice is undeniable. advantages compared with treatment with chemicals. First of all it is:
- absolute environmental friendliness
- complete elimination of pediculosis. Since nits and lice do not tolerate high and low temperatures,
- method availability
- possibility of use without prior preparation.
Like any method temperature effects have several disadvantageswhich include:
- injury risk. Careless use of high temperatures increases the risk of head burns,
- deterioration of the hair structure. Exposure to high temperatures damages the curls,
- the need for repeated procedures.
The method of temperature differences to eliminate head lice belongs to the category of the best, as it allows you to kill lice without the possibility of obtaining a serious side effect. In addition, for better performance, you can combine exposure to cold and hot temperatures.

Pediculosis. How to get rid of lice.
What temperature for lice is comfortable
Parasites have adapted to life on the human body among the hair. These pests did not need to adapt to low temperatures or uncomfortable conditions. At temperatures from 20 to 38 degrees pests feed, lay nits and live for about forty days.
If the thermometer is crawling up or down, the bloodsuckers begin to experience discomfort. When a person with pediculosis catches ARVI, his body temperature will rise. Parasites will prefer to move from the skin to the ends of the hair.
The spread of lice occurs more actively when the body temperature of the patient with lice increases. Pests tend to find a more comfortable habitat. This is one of the reasons why lice are transmitted so quickly in children's groups. The child moves a lot, runs and is in close contact with other children.
The larva inside the nits protects a solid shell, so it is more resistant to temperature extremes. An insect egg can survive even when the air warms up to 50 degrees.
For low temperatures nit is more susceptible. At sub-zero temperatures, the development of the larvae inside the egg will slow down.
At what temperatures lice and nits die
Bloodsucking bugs are sensitive to abrupt changes in the environment. When the temperature drops below 20 degrees, the parasite's vital processes slow down. The pest becomes sluggish, holds its hair weaker and reproduces more slowly. In the body of the female eggs mature not so fast.
If the thermometer reaches 40 degrees, the louse stops laying nits.
Cold exposure
Some people believe that if lice and nits die at temperatures below zero, then it’s enough in the winter to walk without a hat in the open air or dip into a hole. But this method will not work. Faster sick pediculosis sick than lice die.
This happens because the temperature of the human body can not be with a minus sign, and in the scalp of the head is almost always maintained a comfortable environment for lice life. Therefore, the person will freeze, and the cycle of breeding lice will continue.
Durable shell keeps the larva alive for a greater amount of time. If during the appearance of the nymph the conditions are suitable, she will continue her development cycle and turn into an adult individual ready for breeding.
Decreasing degrees has the following effects on insects:
- If the temperature drops below 20, the pests become inactive. The processes of their vital activity slow down.
- When the thermometer shows -5 ° C, the pests stop multiplying and feeding. Nits slow down the development.
- At -15 ° C nymphs and adults die. The larvae inside the egg continue to live.
- Nits die when the thermometer mark drops to -20.
Scientists have repeatedly conducted research, trying to figure out - lice die in the cold or not. Entomologist James Busvin discovered in 1944 that bloodsuckers at -20 became dead after 45 minutes. The death of insects in two hours resulted in a temperature of -17 ° C.
Heat exposure
Head lice are afraid of frost less than heat. From the cold, the insect protects the body and hair of the host. But when a person is sick or moves a lot, he produces too much heat and the parasite tends to move to a more comfortable place.
But SARS or training in the gym can not be considered as a way to get rid of lice on the head. At 40 degrees Celsius above, the insect will only stop laying eggs.
An increase in the ambient temperature affects the vital activity of the pest as follows:
- At a temperature of 40-45 degrees, the female will stop breeding.
- From forty to sixty, adults die, and nits continue to develop.
- The nit can die only when the thermometer shows a temperature above 60.
Scientists found out that lice react more strongly to an increase in air temperature. Their internal organs are destroyed, which leads to the death of the parasite.
If you wash the hair on the head with hot water, the parasite will not die. But the heat will greatly weaken it.
In 2006, Israeli entomologists conducted several experiments and found that at a temperature of + 3 ° C the louse dies on the ninth day.
How to get rid of lice
Head lice kill, changing the ambient temperature is difficult. It is protected from cold by hair, and the person himself will not sustain severe overheating.
Temperature effects are most often applied to body lice. These insects feed on human blood, but live in clothes that are easy to treat with steam or cold.
Heat exposure
To kill a linen louse, it is enough to boil the infected things. Some nits can survive. Therefore, a week later you will need to process the fabric a second time. All this time, clothes should not be worn and should be stored in a tightly sealed bag.
You can kill a louse using high temperatures in the following ways:
- Iron seams, folds, pockets and cuffs of clothes with a hot iron.
- Steam sofa upholstery and carpets.
- Wash things using laundry detergent. Body lice during washing will die.
To destroy the head lice in the United States invented a special dryer. It gives a high temperature at which adults die. In Russia, such a device is not for sale, but you can use the available tools.
- Heat the iron or curler to the maximum and process each strand. Keep the device on the curls 2-3 minutes.
- Turn on the hair dryer to maximum heat. Using a diffuser attachment, treat the hair with hot air for at least thirty minutes.
The iron and the hair dryer are not effective methods of dealing with lice. But the hot air will weaken the insects and their larvae. It should take a comb from the lice and carefully comb the hair from the weakened and dead individuals. The procedure of combing nits need to be carried out at least four times a day.
Cold exposure
Lice die not only from heat. But cold kill head or pubic louse will not work. But low temperatures will assist in the destruction of the wardrobe form.
Our ancestors used snow and ice water to clean carpets and clothing. They noticed that the cold is destructive for parasites. Therefore, in this way they got rid of insects and dirt.
Modern man can follow the example of his grandparents. If it is winter outside, you can take out clothes contaminated with lice on the balcony and leave it there for a day. During this time, insects will die.
Things can not be immediately carried to the house. You should shake them off and choose a frozen animal.
In the warm season freezer will help out. Things need to be folded in a bag and sent overnight in the freezer. Lice eggs can survive the cold. Therefore, after seven days of cold treatment will need to be repeated.
In order to achieve the maximum effect, it is better to process additional clothes with steam and wash them in a washing machine.
Doctors are advised not to treat head lice only by changing temperatures. They recommend connecting an effective antiparasitic drug. To the aid can come folk remedies for lice. If before drying the hair or ironing hair with cranberry juice or vinegar, the insects will become weaker, and the substance that keeps the nits on the hair, dissolve.
Lice life cycle
The development cycle of lice can be divided into four stages: the larva, the first age of the nymph, the second age of the nymph, the third age of the nymph, adult insect. The transition of the nymph to the next stage of development occurs with each molt. When molting, it sheds hard chitinous cover, which allows it to grow further.
- 5 - 8 days develops nit.
- 1-3 days and the larva turns into a nymph of the first age.
- 5 days requires a nymph of the first age.
- 8 days nymph develops second age.
The lifespan of an adult individual is 30 - 40 days.
After the last molt, an adult insect appears and mating occurs during the first two days. A single mating in a lifetime is enough for a female louse to fertilize all the eggs in the body. After that, throughout her life, she lays eggs.
Reference! Female head lice for all life lays 144 eggs, female pubic lice - up to 50 eggs, female body lice - up to 300 eggs in a lifetime. One and a half or two months after infection, a person can have a whole population of insects, and after some time they will cause pronounced symptoms of pediculosis.
Nits and nymphs
Very interesting is the development cycle from the larva to the adult insect. When laying eggs, the female secretes a sticky secret, and only then eggs are born. With this substance, the egg is securely attached to the hair. After that, the secret hardens, forming a "cover" (a kind of handbag, in which the egg matures). This is how nit is formed.
After aging, a nymph of the first age hatch from nits. It looks like an adult insect, only the size and the lack of the ability to reproduce differ. Immediately after appearance, the larva begins to actively feed and molting occurs almost immediately. So the nymph is born.
Methods of temperature exposure to lice
Like other insects, lice quickly adapt to insecticidal agents. However, you can deal with them in other ways. For example, using high or low temperatures.
- - 5 degrees. Parasites stop reproduction and nutrition, slows the development of nits.
- - 15 degrees. Adults and nymphs die, but the larvae inside the eggs continue to live.
- - 20 die nits.
Studies have shown that at a temperature of -20 degrees, the lice population dies completely within 45 minutes.
- From + 40 to +45 degrees females stop laying eggs.
- From + 40 to +60 adults and nymphs die.
- + 60 degrees and above die nits.
There is an opinion that a patient with head lice suffices to walk without a cap in a hard frost and this will help get rid of lice. But it is not. Indeed, in the human body can not be a temperature with a minus sign. And on the scalp of the head there will always be a comfortable temperature for the lice. but it is quite possible to fight with a louse by temperature methods.
Exposure to high temperatures
In most cases, a body louse is exposed to temperature. Since she lives in clothes, and it can be subjected to any processing. But exposure to high temperatures (painless for humans) can help in the fight against head and pubic lice.
Exposure to high temperatures in a louse:
- Ironing things with a hot iron. Particular attention should be paid to the folds, seams, pockets and other details.
- Steaming with a special steamer. Such processing can be subjected to: things, clothes, carpets, sofa upholstery other items in the house. Since the temperature here is very high (more than 100 degrees) most of the lice and nits die immediately. Steaming procedure should be carried out several times.
High temperatures on head lice:
- Iron or curling hair styling. To do this, heat the device to the maximum temperature and process each strand of hair. Each strand should be processed for at least 2-3 minutes.
- Hair dryer for drying hair. It should also be put on the maximum mode and process the hair for 30 minutes. The method is not 100% effective and lice do not die from exposure to these temperatures. But they considerably weaken and worse keep on hair. And it makes combing easier.
After heat treatment, comb the insects with a thick comb. The procedure should be carried out three to four times a day.
Important! The best results in the fight against parasites gives an integrated approach. This treatment of the head with insecticides, heat treatment, combing.
Exposure to low temperatures
Wrestling louse with low temperatures:
- Ice water. In order to get rid of insects, contaminated items should be held there for some time.
- Freezing. If the street is -20 degrees, then for several days you can hold things in the frosty air. This is a guarantee of death of lice and nits.
After freezing things should be subjected to heat treatment (as described above). This approach will increase the chances of success.
Insecticides
Currently, there are a large number of funds from nits and lice.
However, the choice should take into account:
- toxicity,
- aggressiveness,
- efficiency,
- ease of use
- the possibility of allergic reactions.
Therefore, when choosing you need to:
- to study the composition of a drug,
- to study the specificity of the ingredients in the formulation,
- read reviews.
The most popular lice products are:
- sprays
- shampoos
- creams
- concentrates in the form of emulsions.
All of these drugs are fairly easy to use, effective and safe. The exception is concentrated emulsions, they are more aggressive, often causes allergic reactions and burns (if used improperly).
Attention! The main danger of insecticides is allergic reactions.
They appear as:
- dandruff
- atopic dermatitis,
- damage to the scalp,
- pigmentation.
The most popular drugs for lice:
- Medifox with the addition of castor oil.
- Lotion Foksilon. Toxic, but effective against lice and nits, often causes irritation and allergies.
- Medilis-SUPER. A unique preparation for lice and nits. Effective even when lice have developed resistance to permethrin.
- Concentrate Avicin. Concentrated and effective drug. Allows you to get rid of parasites in one application. The active ingredient is permethrin.
- Spray Pedikulen Ultra. Effective due to the content in the composition of alcohol.
- Aerosol Vapor Plus. French drug, contains 3 insecticide. Eliminates lice and nits in one application.
- Spray Nuda. A safe tool for children, the active substance - Dimethicone. The action is produced by causing asphyxia in parasites.
- Spray Paranit. A completely natural preparation based on essential oils, it causes suffocation in parasites and requires twofold application. The product is safe for children.
Very interesting tool - electronic comb Robi Comb. The principle of its action is that it not only combed out, but also strikes insects with an electric discharge. But at the same time its effectiveness is not high.
Attention! Children under 5 years old, pregnant women and nursing mothers are forbidden to use chemicals for lice!
Pediculosis infection and prevention
The easiest way to get head lice is by direct head-to-head contact. Such institutions as: gyms, swimming pools, football fields, children's summer camps, schools, kindergartens contribute to the close contact of children with each other. Most often pediculosis is picked up by children from 3 to 11 years old. This can occur through the sharing of hairbrushes, hairbrushes, hairpins, hats, clothes, and the proximity of clothes on hangers. Lice infestation is not a sign of uncleanliness and poor hygiene.
- You should not change personal things: combs, hats, scarves, you can not use someone else's soap and towel.
- It is not advisable to leave the clothes in the common dressing room in close contact with other people's clothes.
- It should occasionally check your child’s hair and hair for insects. This should be done once or twice a week. Particular attention should be paid to the area on the back of the head and behind the ears.
- Regularly wash your hair and comb your hair with a frequent comb. Especially these measures are relevant in travel and hikes with a large gathering of people.
In the past, head lice was a sign of social ill-being and uncleanliness. Nowadays, the situation has changed and a person from any social stratum can pick up the parasites. One of the reasons is the lack of prevention and information about it. The second reason is incorrect treatment. Often, weak pharmaceutical preparations not only do not remove insects, but also contribute to the appearance of insecticide-adapted individuals. The only solution is an integrated approach to treatment (if necessary), prevention and regular inspection.
Lice on human body
On a human body, lice feel very comfortable. The temperature is optimal, food is enough, nits are perfectly attached to the hairy part of the body. Hair and skin protects the parasites from hypothermia and overheating.
There is such a radical way as shaving hair from the head and body. Shave hair is thrown away, burned, and the skin is treated with soap containing birch tar or pharmacy shampoos, products, etc.
In our time, pediculosis is a very common disease.Infection occurs quickly. Lice, except for the cases listed above, can be picked up anywhere:
- in public transport,
- in the pool, sauna,
- through untreated hairdressing tools, etc.
Very often, the infection can be in a preschool. If the child has pediculosis, he will infect the other children. That is why, to visit the pool, the garden requires a medical certificate.
In any case, the fight against parasites should begin immediately after the detection of the disease. And carry out preventive measures to protect themselves and their families from harmful parasites.
Impact methods
Treatment of pediculosis in this way is a method that is not harmful to health, but is effective and accessible to everyone.
To clean contaminated clothing from lice and nits, you can apply the effect of frost.
Use mainly the following methods of struggle:
- Things that need treatment should be folded in a plastic bag and placed in a freezer. It must be recalled that its power must correspond, since the nits die instantly at -20 ° C. Suitable camera for quick freezing products.
- If it is winter and the temperature is suitable, then just hang out clothes and laundry in the yard for a few days. It should be noted that in the cold some representatives can still survive. Therefore, repeat the procedure after some time.
These methods are universal and do not require financial costs. It is absolutely safe for humans and as effective as possible.
But such methods of freezing are not displayed head lice. It is impossible to create such conditions on the surface of the human body. Hair cover protects against critical frosts, so the lice bury deeper into the heat and save their lives in this way.
Bathing in ice water will also not save: the human body is adapted to such loads and can easily prevent such freezing, even in relation to the skin. And to take out the money, that is, to keep even if it is not -20 ° C, but for a long time, it will not work. With such cooling, the processes in the human body itself are disturbed, which subsequently will cause irreparable damage to health.
Therefore, against manifestations directly from a person, it is worth using heat. For this you can use an ordinary hair dryer. It is necessary to set the maximum hot mode based on the technical characteristics of your hair dryer. Treat each strand with a jet of hot air. It is advised to use a diffuser for heating. Most often it comes with a hairdryer. But if you don’t have one at home, you can buy it separately at home appliances stores.
With this effect, the lice lose the ability to cling normally, they are easy to remove. After warming up the strands, comb inactive individuals with a comb.
The comb should have thin teeth, which are at the shortest distance from each other. Thus, you increase the chances of eliminating all residents, in contrast to ordinary combs. They will comb out both adults and larvae, which will be very difficult because of the large distance between the teeth.
The easiest way to purchase a special comb, which can be purchased at any pharmacy.
Remember that home appliances, in this case a hair dryer, are not designed for too long use at maximum power. In order to avoid breakage, it is necessary to carefully monitor whether the device is overheating. It may be worthwhile to periodically make a pause while using a hair dryer.
As modern medicine continues to evolve, a special medical dryer was invented in America to achieve the desired effect without compromising the health of the hair. There was a lot of discussion about lice, but the idea of creation came to the British professor Dale Clayton, who noticed that it is more difficult to remove lice in rainy England than in the sunny part of America. Having studied the influence of the environment in this aspect, he raised the treatment of lice to a new level.
Unfortunately, this medical dryer is common only in the USA. Recently, this equipment can be observed in other countries, but only in private clinics.
The removal procedure is simple. The patient sits in a chair, and the doctor with a brush of this dryer thermally affects the active individuals. After this comes the long process of combing the already dead units.
The advantages of this device are that it does not damage the scalp, there is no negative impact on the hair structure, it does not reduce their quality. Does not involve the use of toxic substances, chemicals, for the treatment of hair with pediculosis.
As an additional procedure in the process of dealing with lice, you can use the iron to align the hair. It is heated and above 60 ° C, which will ensure the death of the parasites sitting on their hair.
Advantages of this method:
- It is quite hot compared to a hairdryer.
- Convenient to use.
- There is almost every home.
- It is worth being extremely careful, as this heat will damage your hair, make it dry and weak.
- Reproduction occurs more on the scalp, to which the ironing access is not.
- You will need to repeat it several times, rarely you can achieve the result from the first time.
There are a number of less reliable ways, but they are captivating for its simplicity. For example, if you live in a country where it is mostly always hot, go to the beach to sunbathe. Such a procedure calls into question the question of whether the louse dies on the beach. A few hours under the scorching sun, if not killed, then just weaken them. Plus, high humidity will play into your hands in the fight against this disease.
A good way - to go to the bath and relax. For lice, their larvae, eggs, such an environment is destructive. The advantage of this event is a positive influence on the person himself and his general condition.
The main and main disadvantage of this procedure is that the bath and all its premises after it should be carefully processed. Pediculosis is a highly contagious disease. And not all the rooms, waiting rooms, showers, support all the necessary conditions for the death of these creatures. In order to avoid contamination of all the following guests, the treatment should be carried out very carefully.
Do not forget that the clothes and underwear in which the linen representatives of this species have settled can also be processed with the help of high temperatures.
The first method is the easiest. It is necessary to load things into the washing machine and set the mode in which it will be at least 60 ° C. Washing will show a positive result, which does not keep you waiting.
If you do not have a washing machine at home, you can use another method to combat laundry lice. Immerse the laundry in the largest saucepan, put it on the stove and simmer for an hour. In such conditions, no form of these parasites survives.
As a separate method or additionally after washing, iron the clothes with a hot iron. It should be noted that very often the louse with the offspring huddle in folds and seams. Therefore, pay particular attention to ironing these places.
Unambiguous advantages of these methods of processing things is that everyone can use them at home. A positive characteristic is that only one procedure is enough to achieve the desired result.
These simple tips will help you in the fight against the manifestations of lice without financial costs and harm to health!
