Causes
By Mayo Clinic staffBody lice are scientifically known as Pediculus humanus corporis. Body lice are a different type of lice from those involved in head lice and pubic lice infestations, though they're all similar. Body lice are the largest of the three types.
Body lice feed on your blood but primarily live and lay eggs (nits) in your clothing. Body lice infestations are caused by exposure to body lice or their eggs through:
- Direct contact with someone infested with body lice. This is why body lice are particularly common in people who live in crowded conditions.
- Contact with infested clothing or other items. Infested items may include clothing, bedding and towels. Body lice can survive on these personal items for as long as 30 days.
