Pubic lice ('crabs') are tiny blood-sucking insects that live in coarse human body hair, most commonly pubic hair. They cause itching and red spots.
They can usually be successfully treated with insecticide medicines available over the counter in most pharmacies, or from a GP or GUM clinic.
It is important not to use treatment for head lice on your genital area as this may cause burns on the delicate genital skin.
