4. Life Cycle

Adult body lice lay twice as many eggs as head lice, around 180 during their life cycle. The yellow or white oval-shaped eggs hatch within one to two weeks. These hatchling or nymphs begin sucking blood immediately, feeding every five hours. They mature into adults 10 days later. The tan or grey-colored adults have six legs and are about the size of a sesame seed. Without a host, body lice live from five to seven days at room temperature.
