LICE

The condition in which the hair, body and clothing are infected with lice is known as pediculosis. There often aren't any easily visible symptoms and the most common and dramatic manifestation of pediculosis is itching – which can be severe. Three main types of louse affect human beings. These are pediculus humanus capitus (the head louse), pediculus humanus corporis (the body louse) and phthirus pubis (the pubic or crab louse). There are quite a number of ways treating lice once they have been identified. Some of the most useful products contain either malathion or gamma benzene hydrochloride. Although you should obviously follow the instructions on the product you've bought, in most cases a single application will be enough.
