Body Lice

Body lice are tiny insects, about the size of a sesame seed. Body lice live in your clothing and bedding and travel to your skin several times a day to feed on blood. The most common sites for bites are around the waist, groin and armpits — places where clothing seams are most likely to touch skin. Lice causes severe itching. Itching is usually worse around the waist, under the arms, and places where clothing is tighter and closer to the body (such as near bra straps). You may have red bumps on your skin. 

Body lice mainly live in clothing. To get rid of lice, destroy infected clothing or carefully wash items in hot water (at least 130 degrees F), then machine dry using a hot cycle. Your doctor may also prescribe a cream that you put on your skin or a wash that contains permethrin, malathione, or benzyl alcohol. Bathing and washing clothes, bedding, and towels are most important steps in treating lice. Doing these things usually gets rid of the problem.
