The pubic louse is about the same length as the head or body louse but has a wider body. Body lice can be found in any area of the body, although they tend to avoid the scalp, except at the margins. Nits are laid in the host's clothing and are not usually found on the hair as with head lice and pubic lice.

Lice are very, very small insects. In fact, they are so tiny that you can barely see them! Each louse (the name for one of the lice) is only about the size of a sesame seed. Head lice need to be next to skin to survive — and the warmth of your skin is a perfect place for them to live.

Head-to-head contact with an already infested person is the most common way to get head lice. Head-to-head contact is common during play at school, at home, and elsewhere (sports activities, playground, slumber parties, camp). Although uncommon, head lice can be spread by sharing clothing or belongings.
