They usually only move to the skin to feed.Body lice are one of the three types of lice that live on humans. The other two types are head lice and pubic lice. Each type of lice is different, and getting one type does not mean that you will get another type.Body lice can spread diseases, such as typhus, trench fever, and relapsing fever.How do body lice spread?Body lice move by crawling, because they cannot hop or fly.
