Body lice are tiny insects that live on the human body, primarily in clothing and bedding. They feed on blood and can cause itching and discomfort. Unlike head lice, which infest the scalp, body lice are found in areas where clothing is tight against the skin. These pests are often associated with poor hygiene and crowded living conditions. Body lice can spread diseases, such as typhus and trench fever, making them a public health concern. Regular washing of clothes and maintaining personal hygiene are effective ways to prevent infestations.
