Pediculous: How to get rid of lice on clothes and bedding? Where do you live and what do we eat? Whether live in water.

Parents whose children were diagnosed with pediculosis, often looking for information about how many crides live. But this question is not correct, since the GDID is not an independent alive insect, it is the eggs of lice in special shells. They do not need food. Without a person and in normal conditions, they retain their viability for a long time.

Evolution took care of the peculiarities of the structure of this insect. It is perfectly adapted for life practically in any conditions. The structure of the body and the characteristic features of the stallows at the ends of the paws - everything says that he should live on the human body.

There are varieties that can be located and feed on other parts of the human body. For example, a wrapping type and can live on clothes and move to the body when the clothes were won. The same pubic lunch lives only in armpits or in pubic hair.

Infection of the head of the pubic login is possible only in children.

Stages of development of wedge

Gits are developing from 7 to 10 days. Eggs of the wrench can develop up to 2 months, provided that the GIDID is developing at room temperature. At low temperature values, development can delay up to a year.

When the temperature drops to -1 ° C or below, the ninomas are able to live only one week. As for the development of nymphs, or larvae, the process also proceeds faster - under favorable conditions for 15-20 days. Adults are lived for 40-46 days. The life expectancy of insects inhabiting clothes is about 40 days.

Despite the fact that the life of the lice is fleeting, she has time to go through several stages. Insect there are only 3 molts. They begin every time chitinova "clothes" for nymphs becomes small. When the third link ends, the nymph becomes an adult insect. The female can postpone on the day 2 - 4 eggs. For his short life, VSH has time to postpone 140 eggs.

Despite the fact that you have a different structure, their individuals placed in limited space begin to cross each other. After a few generations, the differences disappear.

When the larva hatching out of the egg, the insect can pierce the crides with his jaws, but it is not able to get out of it alone. The larva begins to actively breathe. In this case, the air passes through the digestive system of the insect and goes through the rear pass. When the air accumulates the bottom of the inclination in large numbers, he pushes a larva from a cavalry that gets on the skin of the hair cover and begins to suck blood.

How to get rid of lice?

Knowing that Vership lives outside the head is not so long, it is required to find an effective way to get rid of them. These unsubstantial creatures, among other things, are carriers of such hazardous diseases like a typhoid.

You can learn about pediculose by characteristic features. Man torments itching. He has bluish traces on his skin. The person worsens well-being and mood, sleep is disturbed. If the inspection was discovered non-crude guests, it is necessary to go to the pharmacy. Tell us about the problem, and the pharmacist will advise you the optimal means.

It is necessary to do this, as the sews live without a person for a few days, and if suddenly the disappearance of the "will decide" return, preventive measures will be necessary.

Sometimes you can apply a radical way - shave sticky. The combing is much more often used. The method works perfectly in combination with the use of drugs. Special combs quickly free hair from the GDID and lice. They are not difficult to use. Treat your head with the means.

Head Lush has a brown coloring, insects living on clothes - white

However, if we arm a magnifying glass, then you can see how it looks like in reality. She has all parts of the body characteristic of other insects: headband, abdomen, mustache and six paws. Surrently, living on a man's head, has a gray or brown color, but the wrench wrench, who choose the wrestling medium, painted in white.

They have no wings, so they do not know how to fly. They are not capable of jumping, but they quickly run through the hair. Therefore, the most often insects are infected by children, because during the games they often contact each other.

If the nisses lead a passive life, then the translucent larvae of lice are active in no less than their parents.

And anxiety is delivered to your carrier as much as they feed with human blood.

The rice apparatus of lice and insect larvae is an ideal tool so that they can pierce the human skin, and then drink blood from it.

How long can you live without a person

To get to the human body, in a variety of ways. It can be transport, school, hospital.

Go to the person can also come from items around him.

It can be clothes, bedding, comb. As soon as they got into the human body, it hurts tightly into the hair and begins to multiply, laying eggs.

Versh and nits are very firmly attached to the hair

How much does it live out of a person? There is an accurate answer to this question. She can't live without food. Insect for two days, the insect will not find food for themselves (that is, it will not settle on a person), it will die.

In order to make an adult sex from the egg, it takes not too much time. On average, it will be necessary for about 15 days. However, if the conditions for reproduction are not too favorable, then this process can stretch for a month.

The full development cycle in 15 days passes

Insect development is divided into the following stages:

1. At one time, the adult female postpones up to five eggs, which it firmly fixes on the hair. The place for this purpose she chooses as close as possible to the skin of the head, sticking the eggs with an adhesive substance existing in the outer sheath of the eggs. On the development of Nicky to the larvae leaves five to eight days.
2. The appeared on the light of the larva looks like a small loss, but the genital system is still in the underdeveloped state. After the first meal, she has a molting. From this point on, the larva is called the nymph. The first stage of its development lasts about five days. Since the nymph lins three times, then she has three development steps. The molting occurs because her shell consists of chitin, so it cannot grow with it, it cannot. You have to change it.
3. After passing all the stages of development, the hatched larva becomes an adult part. This stage is called Imago. The female immediately finds himself a couple and on the same day begins to postpone the eggs. Sometimes it happens just a few hours later. For more information about how VSH appears, see this video:

Places where the loss lives in man

Obviously, the insect clings to the hair very firmly, but this happens only because it can fall during hygienic procedures. However, the hair is not the only place for their habitat. It is at the place where the lice live on a man, they are divided into three types:

• linen;
• pubic;
• head.

However, you should know that before their use, you should carefully examine the instructions, since there are many contraindications to use them.

Such drugs can not use pregnant women, with asthma and allergies. They can cause poisoning of young children.

Funds made from the richness, chemaches, Pijmas are safe for children

• decoction or the juice of the richness and cheer;
• decoction of pyrms;
• vegetable oil;
• cranberry juice;
• hair spray.

To avoid infection with lice, simple hygiene rules should be observed, the main thing of which is not to use personal things of other people's people. Combs, hairpins, towels, which other people use, can become sources of infection with pediculosis. You can not wear hats belonging to the strangers. All family members must systematically check themselves to make sure that there are no pediculosis.

Vershi is a segmental insects that belong to the subclass of the winged insects, infrack beneath the insects, the detachment of the Pukchids and Versh, the suburia of the Vershi (Lat. Anoplura.).

International Scientific name: Anoplura. (Leach, 1815).

The origin of the word "loss" is clearly not defined. In Slavic languages, these insects are called very similar: in Ukrainian - Vosh, on Bulgarian - Entry, in Serbian Vashka, on the Croatian and Slovenian Uš, on Czech veš, in Slovak Vši, on Polish Wesz. At the heart of all these names, like the ancient-Russian entry, lies Praslanjanskoye * V. It is possible to origin from the ancient-Indian "VAS", which means "there", that is, the company is what eats.

Vershi - description, characteristics, photos. What do lice look like?

Switch is an insect, having small sizes and a flattened torso, compressed from the back to the abdomen. A narrow or wider body reaches 0.5-6.5 mm in length and 0.2-2.5 mm wide. Males usually smallest females.

The body of the Wrench consists of sedentary departments: heads separated from her chest and abdomen. The head may have a different form: a narrow-handed, hexagonal, narrowed in front of a mustache, sometimes very elongated. It is pregnant, that is, right towards the body.

On the head, several parts separated from each other seams are isolated: the top lip, the platband, the forehead, the head and the theme, sometimes separated by the seam on the right and left parts, called eye blades. On the front of the front, and more often the middle part of the head grows the filamentous mustache consisting of 3-5 segments. On the last two segments there are sensitive pits. On the final segment there are sensitive appendages. The males are the third segment of the mustache with the protrusion (apply) carrying a spike or bristle, and the first segment is noticeably larger than the females.

Behind the mustache, that is, on the sides of the back of the head, there are one-cylinder reduced eyes: hemispherical or cone-shaped, with a pigment spot or without it. Many varieties of lice are considered lightly. Vision in lice is very bad: insects perceive only light and focus with the help of the assholes that cast odors.

From the abdominal side, lice has a river hole located on a ring fold, departing from the front edge of the head. It is a short oral melting cone with small chitinous hooks. It is them that I am attached to the owner's skin in order to suck blood. The river apparatus of the chipping-sucking type is located in a special capsule located inside the head. It is drawn into a capsule when the insect does not drink blood, and put forward with the corresponding muscles during the meal. The oral apparatus consists of the upper, middle and lower stallers.

• The first stilelet has the form of double gutter and together with the passage formed by the groove-shaped robes of the oral cavity, serves to pass the blood into the throat, operating with special muscles as a suction and injection pump.
• The second stylet is a soluble tube into which the overall dumping of the salivary glands passes.
• The third stylet is prickly. It consists of a toothed peak and a gutter, where two first stages are lying.

Rota apparatus

The chest of lice consists of three closely fused parts: forwarding, middleware and tempering. In size, it can be shorter than the head, and its form varies from elongated-oval to hexagonal. On it there are a pair of mediterranean breath (stigma) and legs: they are not developed equally and sometimes vary in males and females.

Despite the fact that the lice belong to the subclass of the winged insects, they do not even have the rootings of the wings. Vershs do not know how to fly: like, they have lost the wings during evolution.

Feet in lice five-alkaline, grabbing type, very chain and durable. They consist of a basin (or cokes), hetervuga, hips, legs and legs with 1 or 2 segments. Front legs less than medium or rear. Latest segments, shin and foot, often combined or unclearly separated. On the extended shin there are spikes, bristles and protrusions. The foot has a smooth or furridge cowing of the sickle shape and different lengths, sometimes with a clawding appende. With the help of all these devices, it is very firmly cling to the owner's hair and climbs on them. During the movement, the insect grabs the hairs to the shin, pressing him to the tibia. By the way, there is a notch in the shin where the cohotok is precisely.

Enemies of lice in nature

Natural enemies of lice are, as well as some predatory and insects.

What eat lice?

All lice feed on the blood of their owners. The larva begins to eat after 20-30 minutes after his appearance. In this case, the head insects hold under a stupid angle to their body. Salus, standing out by the insect, falls into the wanted wound, and prevents blood coagulation. In the insect stomach, an active peristalistic takes place: it is filled with blood, and after 12-17 minutes, excrement, which have a kind of reddish fluid and harden after another 3-5 minutes.

The frequency of the supply of lice for complete saturation varies from different species and depends on some external factors, for example from temperature. The higher the temperature, the more often the insects suck blood. Some types of lice eat almost continuously, distracted only for movement and reproduction, other species make breaks. Usually insects feed on the blood of one type of animals, but if necessary, they can change the host for a while.

Where do Vershi live?

The lice is found on many animals, including home, belonging to various detachments: on, earthmocks, sonaches, mummifs, various types, including mice of houses, voles, pipes, damasters, buffaloes, donkeys, seals, and so on. One of the affected mammals affected is a person.

At the same time, there are a number of animals that have never found insects from the lice sublist (Lat. Anoplura.) (PiotrownSki, F. (1992): Anoplura. (Echte Läuse). de Gruiter; 61 p. (p. 8)):

1. The detachment is single-pass (lat. Monotremata.) (such animals, like echidnas, walls),
2. Final detachment (lat. Pilosa.) (These are different sloths and amusements),
3. Pangoline detachment, or lizards (lat. Pholidota.) (It includes various lizards),
4. Detachment manochable (lat. Chiroptera) (these are wings and bats),
5. Catto-shaped squad (lat. Cetacea.) (these are whales, dolphins, coushlots, sea pigs),
6. Sirena detachment (lat. Sirenia.) (these are Dujoni, Lamantins and marine cows),
7. Detachment of probitive (lat. ProBoscidea.) (These are elephants). Earlier, elephant lice attributed to the suburior of Anoplura, but then they were brought to a separate cross

If the owner dies or fever (the temperature rises), the lishes rise outside, to the surface of the hair cover or clothing, and partially disappear or scatter.

How many lice live?

The life expectancy of lice, among the studied species, is most often 2-4 weeks, the maximum - about 2 months. Life life of males is significantly less than the females.

No food (without a person or animal), the lice live long: from 1 to 7 days (according to some data up to 10 days). The higher the air temperature and dryness, the less life. Just hatched larvae, not having a host, die after a shorter period: from 12 hours to 4 days.

How to multiply lice?

Life cycle of lice looks like this:

Life cycle

Version multiply by laying eggs. The hawk female lays eggs, regardless of mating, but neople-specific eggs do not develop. Falling the female may soon after their appearance. Pairing occurs within 10-70 minutes. The male is under the female and holds it or only the first or first and second pairs of feet.

Each female lays out from 4 to 14 eggs, depending on the type. In total, it postponed an average of up to 329 eggs. Eggs are especially visible on rack-haired animals, on clothes, and then it seems that the surface is all sleeping with them.

Eggs of lice are called shortcuts. They are coated with solid shells, have an oval, pear-like or unilaterally compressed form and an average reach 0.5-1.5 mm in length and 0.2-0.7 mm wide. On the color of the nice white, yellowish, rarely with a weak pearlescent gloss.

Eggs (nits). Taken from the site: www.nhs.uk

The front end of the egg is a cover, which opens at the birth of the larva.

At the bottom end there is a glue mass (a special adhesive secret), which it is attached to the hair's hair.

Structure of Nicky: A - Lid, B - Shell, C - Hair, D - Large

The larvae-out of the egg (it is nymph) looks like an adult insect and differs only by smaller dimensions less than the arrangement of bristles, as well as the absence of genital organs. During its development, the larva, the lice lins three times, while maintaining the white, almost transparent color of the body. In the process of growing, the size increases, pigmentation and sclerotization increases, the number of bristles increases, and genitals appear.

The larval stages of lice continue 2-3 days. To sucking the blood of the larvae is ready in 20-45 minutes after hatching, and sex maturity occurs after 1-7 days. The full life cycle of different types of lice continues until one and a half months, depending on external conditions.

Types of lice, titles and photos

The following is a brief description of several varieties of lice, which differ from each other by appearance, the choice of the owner and the spreads in its body.

The insect has a size of 1 mm in length (in males) and 1.6-2 mm (in females). The body is short and wide. Feet are directed to the sides. The head seems to be cut in front. The breast is the wider part of the body, convex from the sides, with dark pigmentation. The abdomen is short. The female lays no more than 3-4 eggs per day. A full life cycle varies from 22 to 27 days. Under normal conditions, the length of the life of the female reaches 17 days, the male - 22.

The pubic lice is low-lived, for a long time are in one place, immersing the trumps into the body of the owner. Eat with frequent interruptions. Without food withstand 1-2 days. Infections are not transferred. Geographically distributed worldwide.

The female postpones 1-2 eggs 3 days after the last larch molting. For life can postpone up to 50 eggs. Life expectancy of females - 3-4 weeks, male - 2 weeks.

Pork heming dwells around the world. On the body of the pig is located locally on areas with delicate skin: on the ears, blades, the inner surface of the hips. On young piglets are located all over the body. This type of lice is a carrier of pork plague and Siberian ulcers.

Insects have a narrow, cone-shaped in front of the head with a weakly rounded rear edge. Its width 2.5 times less than the length. The chest is significantly shorter than the head, the sides are almost parallel. Abdominal egg-shaped oval. Body length 3 mm in males and 3.5 mm in females.

Eggs are developing within 11-20 days. The larvae grow up for 11-12 days. Without the owner, this loss can exist 4-7 days. It is the carrier of infectious anemia of horses.

Insect head long: its length exceeds the width. Breast is wider and shorter heads. Abdominal oval. A mustache mustache are attached to the middle part of the head. The length of the female body is 1.8-2.4 mm, male - 1.6-1.7 mm. Females fasten eggs to single hairs or to their group.

• Linognat Ovechy (Lat.Linognathus. ovillus. ) lives at different parts of the body of home sheep. Females reach 2.8 mm, males - 2.1 mm in length.

The head is elongated with the cone-shaped front. Breast short, slightly head. Abdominal oval.

The insect has a body length of 0.8-1 mm in males and 1-1,4 mm in females. The head is convex in front and cut from behind. Chest is a little wider head. The belly is narrow-oval. Feet of different sizes. The first pair of smaller length, the second is more, and the third largest with a strong thick claw. Insect on the head, neck and rodent blades, less often on the sides and hips. In the same places, females lay eggs.

The life expectancy of the Wrench without a person depends on how long it can hold out without food.

The duration of the life of the adult dog is thirty days.It is during this time that the female postpones about ninety eggs. After the incubation period (7-10 days), the nitrate hatches. In the next ten days turns into an adult person. The cycle is then repeated again.

As regards the GDID (Eggs of Lisha), then in this case the situation is different. Gyde, concluded in a dense shell, can remain alive without a person 3-4 days and hatch only when favorable conditions for survival will appear.

Can lice live in things

It is overwhelmed with all available funds in the fight against lies, and the problem of pediculosis occurs again. What is the matter?

Blood-axes are capable of living and multiply not only on human hair - this is a fact.

The lice dwell in objects of textiles, namely:

• clothes;
• bedding;
• upholstery of sofas, chairs;
• pillows (and not always feathers).

Padiculose pathogens feed on only human blood. Hence, the environment of their habitat is closely intertwined with human skin.

Lower lighters can do without food for a longer time.Therefore, they can most often find:

• on clothes, in particular, on underwear;
• on upholstered furniture (especially susceptible to the soft upholstery of the sofa and bed);
• on bed linen (pillows, blankets, mattress).

Handling inhabited only on clothes. As soon as a person puts in an infected outfit, he immediately begins to bite small bloodsowing insects.

Is it possible to get infected with lice without contact with a person

The problem of pediculosis is quite common, therefore, there are many of the question, is it possible to get infected with lshami without contact with a person?
