These Crab louse are commonly found on the coarse hairs of the body especially pubic hair, axillary hair and other regions like beard, moustache and even on eyelashes. The adult insects are about 2 mm long and exclusively feed on human blood. The insects reproduce by laying eggs. The female lies about 3-4 eggs in a day which hatches in about a week to enter nymph stage. This takes about 10 to 17 days to become an adult. This infection is usually spread through direct contact, particularly sexual contact. Fomites including clothes and bedding infested with the parasite can also spread the infection [3-5].
