Head Lice (Pediculosis)

Lice are tiny insects that live on and crawl through the hair. They are gray, brown, or black and can be difficult to see. They do not leave the human host on their own - they must be physically dislodged. They do not infest pets, furniture, carpeting or toys. Head lice live only on the heads of their human hosts.
