Pediculus humanus corporis, commonly known as the body louse, is a parasitic insect that infests humans. It is typically found in clothing and feeds on human blood, which can lead to itching and discomfort. Body lice are often associated with poor hygiene and crowded living conditions. These lice can transmit diseases, such as typhus and trench fever, making them a public health concern. Unlike head lice, which live on the scalp, body lice prefer to reside in seams of clothing, laying their eggs there. Maintaining cleanliness and proper hygiene can help prevent infestations.
