The body louse (Pediculus humanus humanus, sometimes called Pediculus humanus corporis) is a louse that infests humans. The condition of being infested with head lice, body lice, or pubic lice is known as pediculosis. Nits are louse eggs. 2  They are generally easy to see in the seams of an infested person's clothing, particularly around the waistline, under armpits or even in body hair. 3  They are oval and usually yellow to white in color.
Head lice (Pediculus humanus capitis) feed on blood, primarily on the heads of children. Infestation by head lice is called pediculosis. Fortunately, they do not transmit disease, although their presence can be very bothersome. These lice inject a saliva into their hosts as they feed to prevent the blood from clotting.
