This document discusses pubic lice (crabs). It defines pubic lice as tiny insects that live in pubic hair and cause itching. Symptoms include intense itching in the pubic region that is usually worse at night. Pubic lice can be transmitted through sexual contact or close personal contact with an infected individual. Treatment involves using over-the-counter medicated lotions or sprays to kill the lice and nits. All affected clothing and bedding must be washed or dry cleaned to prevent reinfestation.
