- This is an infestation of tiny, parasitic insects (singular louse) that attack the skin of the scalp, trunk, and pubic areas. Lice infestation is transmitted person-to-person and via intimate objects that tend to be shared (brushes, combs, towels, hats, etc.). Lice are 3-4 mm long, making them barely visible to the naked eye. Body lice are usually found in the seams of underclothing, and generally go to the body only to feed. Hair and pubic lice are located in these areas.
