Nits are the eggs of lice. Humans can be infested with three kinds of lice: Pediculus capitis (head lice), Pediculus corporis (body lice), and Phthirus pubis (pubic, or crab, lice). Lice feed on human blood and deposit their eggs (nits) on the hair shafts (head lice and pubic lice) and along the seams of clothing (body lice). The nits are attached to the hair shaft or clothing with a strong cement.
