The crab louse is called Phthirus pubis or pubic lice. It’s easy to tell the difference between human lice and crab lice. The human louse has a large abdomen. The abdomen of the crab louse is wider than it is long and has small protuberances on each side. Crab louse nits are smaller than those of the head louse and the body louse, and the crab louse uses more glue to stick the nit to the hair.
