There are 3 types of lice: head louse, body louse, and pubic louse.
Head lice are parasites: tiny insects with hooked legs that cling to the hair. They are parasites that need our blood to feed and our hair to lay their offspring. Nits, on the other hand, are the eggs laid by the female louse. They are translucent and often more visible than the lice themselves. The nits are found more on the lengths of the hair.
Pediculosis corresponds to an infestation of parasites and lice on the scalp.
The lifespan of a louse is two months on a scalp. Outside the latter, deprived of blood, he cannot survive. Head lice are the most common and mainly affect children aged between 6 and 8 years old in the community. The louse has a life cycle comprising different stages:
- The female louse lays the eggs; these are the nits
- In 1 week, these nits turn into larvae: these are the nymphs
- About a week later, the louse becomes an adult
Body lice are present in clothing. It is then advisable to consult a doctor specializing in dermatology such as LiceDoctors for example. As for pubic lice, called crabs in common parlance, they are transmitted during sexual intercourse (infection).
