The Life of Lice. About the size of a sesame seed, head lice, six-legged parasites that live on the human head, are hard to see. And nits -- eggs that females glue onto hairs near the scalp -- are even more difficult to spot. But, luckily, lice can't live more than a few days away from the warmth and food the human head provides. And though they are hardy in some ways -- they can survive submersion for up to six hours (that's why swimming and showers don't kill them) -- they can't jump, hop, or fly.
