Lice are small in size, about a sesame seed. They are painted in gray-brown color, have 6 legs, thanks to which they quickly move through the hair. If the louse is drunk with blood, it becomes red or black. Lice feed constantly so as not to die. Insects lay oval eggs with a yellowish size of no more than a millimeter, from which a new individual emerges a week later.
Otherwise, the eggs are called nits, they can be easily confused with dandruff, but unlike them, they are firmly glued to the base of the hair with a special substance. They can not be shaken off the hair, so the nits are carefully combed out after the treatment. Head, pubic and body lice can live on a person, each of which differs in size and places of congestion.
Dark color, long abdomen are lice in the head of a person. They are called head because they are concentrated on the hair, females are larger than males. This type is characterized by rapid reproduction. After laying the eggs before the maturation of the female with reproductive ability, only 16 days pass, and under adverse conditions – a month. Head louse is extremely productive – for its life, which lasts up to a month, it lays 80-100 eggs. It turns out that on the day she lays 3 eggs, which quickly turn into adults and pester the patient.
The stages of the life cycle of a human head louse causing lice:
- 1 mm egg develops a week;
- 3 stages of the nymph, at which the future insect grows, molts, for 3 days it turns into a nymph of the first age, for 5 – the second, for 8 – the third;
- stage of an adult insect – a nymph molt and is ready for reproduction, it begins to mate with males immediately after leaving the nymph.
Darkish in color with a wide, strongly shortened abdomen, lice belong to the pubic areas. Their habitat is groin, buttocks, armpits, eyebrows and eyelashes. Pubic insects differ from the head structure of the legs, but the cycle of their development is similar in view of the same breeding conditions. Females lay up to 50 nits, they feed heavily on blood, form nymphs of the first, second and third order, then an adult individual hatching – an adult.
Clothes lice live on clothes and chest hair. They look like a head, but differ in a yellowish color without black dots on the abdomen. These lice lay more than 300 eggs during their life; they are characterized by increased resistance to cold and starvation. You can destroy nits, nymphs and adults only by boiling. Bites of clothes insects look like scabies, blood points turn into follicles and become inflamed.
