Causes

Body lice are similar to head lice but have different habits. While head lice live in your hair and feed on your scalp, body lice usually live in your clothes and bedding. They travel to your skin several times a day to feed on blood.

Your clothing seams are the most common places for body lice to lay their eggs (nits). You can become infested with body lice if you come into close contact with a person who has body lice, or with clothing or bedding that is infested with body lice.
