Lice are tiny parasites that live on human beings and feed on blood. They seldom cause serious medical problems, but they are both annoying and contagious. Every four hours or so, a louse bites into a tiny blood vessel for a meal. You don't feel the initial bites, because lice inject an anesthetic. However, the bites later begin to itch, and your scratching can lead to Problem created due to harmful organism.

Head lice (Pediculus humanus capitis) are about the size of a sesame seed and can be easily seen, although they hide quickly in response to light. Their eggs, called nits, are barely visible, whitish ovals cemented to hair shafts. Head lice are extremely contagious, especially among schoolchildren. They afflict an estimated 6 million to 12 million children in the United States. Twice as many girls as boys get head lice, not because of greater hair length, but because girls have more physical contact with one another and share more personal articles (hats, clothing, combs, headphones) that can transmit head lice. Head lice are rare among African-Americans, possibly because the shafts of their hair have a shape that lice cannot grasp easily. 

Pubic lice (Phthirius pubis) are yellow-gray insects found in the pubic region and transmitted by sexual contact. The size of a pinhead, they are slightly translucent and barely visible against light-colored skin. They are also called crab lice, or crabs, because of their shape and the crab-like claws with which they cling to hair. Eggs can barely be seen as tiny white particles glued so firmly to hair shafts that they are not removed by normal washing. 

Body lice (Pediculus humanus corporis) are nearly identical in appearance to head lice but are more difficult to find. When not feeding, they tend to hide in the seams of clothing and folds of bedding. Signs of their presence are scratch marks, hives, or small red pimples, usually on the shoulders, torso or buttocks. If the lice are not treated, rashes or welts may develop.
