Many people mistakenly believe that lice can live exclusively on
human head, but it is completely wrong. In addition to the hairy part
scalp parasites live on:
- Eyebrows – the case when lice are moving with
hair. Causes itching on the face and redness on the forehead.
- Eyelashes – just like in the first case, this
parasites migrated from the head. Often their appearance
accompanied by redness of the eyelids and conjunctivitis.
- Beard – live on hard hair
called pubic lice. They are distinguished by the special structure of the limbs,
allowing them to cling to thick rods.
- Breasts – if the chest is covered with hair,
there is a risk that pubic lice will settle on it.
- In the armpits – common
location for parasites, subject to increased body hair.
- In the groin – lush vegetation in the “bikini zone”
favorite place for pubic lice.
Reference! Help – pediculosis is not identical
uncleanliness. Even a neat person can pick up lice when
contact with an infected person or his or her personal belongings, as well as in
public “densely populated places”: transport, social
institutions, saunas, beaches.
Where do lice live at home (apartment)
Lingerie as a species does not exist for too long – they
appeared at the same time when people started to cover their
nudity Remarkable, but precisely this insect’s DNA
helped scientists to establish an approximate date of creation of clothes.

for this. But these parasites feel quite comfortable on
“stale” clothes. They can be found:
- pleated and pleated;
- in turns;
- under the seams;
- in pockets.

habitat more comfortable and safe. In addition, clothing

Can lice live in things, on clothes, in bedding and
When the problem of pediculosis occurs again and again has
sense to check and process everything that regularly comes in contact with

textiles ranging from bedding to furniture
But at the same time, it often happens that lice are confused with bedbugs and
fleas. You can distinguish some parasites from others by the following
- A louse, unlike a flea, is not capable of jumping.
- The bug, unlike lice, can be discerned unarmed
with a look.
How many lice and nits live outside the human head?
The lifetime of the insect outside the hair
cover at an average room temperature of 23 ° C does not exceed
four days. A sharp jump in the thermometer to 30 ° C causes
death of the parasite during the day. If the temperature, on the contrary,
drops to 10 ° C – the protective mechanisms of the louse turn on and it
hibernates. In a state of anabiosis she can live
10-12 days. As for severe frosts, the louse dies when
temperature of -20 ° C.
Lice life cycle
The life cycle of a head louse is rather short, but is saturated with
developments. Conventionally, it can be divided into five stages:
- Infection – immediately after contact with the body
human louse is looking for a partner for mating, then nourished
blood and goes to the laying of eggs.
- The development of nits – the body of nits is protected by a capsule,
consisting of special glue and durable substance. She protects
developing parasite from chemical and mechanical effects.
This whole “construction” is mounted on the hair shaft. Stage average
takes 5 to 10 days.
Reference! Nits at the development stage do without
nutrition and oxygen, so oil antiparasitic agents
aimed at closing the airways, save only from
- Larval stage – when the splinter matures,
she is not ready to leave the protective capsule immediately. Therefore she starts
gnaw her, accumulating carbonate in the lower part of her torso
gas, which by its pressure pushes the parasite out.
- Turning into a nymph – this stage takes from
one to ten days, depending on the environmental conditions.
During this period, the larva more and more begins to resemble
adult When the transition is complete, the louse
drops chitinous shell and is covered with a hard shell.
- Transformation into an adult. Nymph passes
two stages of development, each of which ends in a molt. On
This stage is the formation of the reproductive system. Evolution
Nymphs in imago takes five days.
The adult, sexually mature louse lives from 30 to 42 days,
after which he dies, leaving the place to his posterity.
What feeds on and how does a louse breed?
Female lice begin to mate with the males already in the first hour after
exit the nymph stage. One pairing is enough to
all eggs were fertilized.
Then, every day, the female lays several gn.
the amount depends on the type of parasite:
- At the head – from 2 to 4 per day, and from 80 to 140
for the whole life.
- In the pubic – from 1 to 3 per day and up to 50 per
- In wardrobe – from 2 to 10 per day and up to 300 per
As for food, the louse, contrary to common
To delusion, it feeds not on human hair, but on blood.
She usually eats just before mating – bite
feels like a light, itchy tingling. The problem is that what
the earlier the stage, the less likely that a person will begin
treatment – because the bites and their effects are felt for about 2
week after infection. That is, already when on the head
several generations of pests.
