Body Lice

Body lice: Overview

Body lice are tiny bugs that can live in the seams of clothing or bedding (sheets, pillows, and blankets). They are hard to find on the body. It's much easier to see lice or their eggs (nits) on clothes.

Body lice are most often spread by contact with a person who has body lice or with that person's clothes, bedding, or towels. They are usually found only when people can't wash their bodies or their clothes regularly.

Lice can cause very bad itching, especially at night. They can also cause sores in the armpits, waist, or torso. These are places where the seams of clothing can press against the skin. In rare cases, body lice carry disease. This usually only happens when people are living closely together in places where they can't bathe regularly.

Most people can get rid of lice by washing personal items and their bodies regularly.
