Pubic crabs are tiny parasitic blood-sucking wingless insects that infest the human genitals, causing itching and red spots.

Pubic crabs affect sexually active adolescents and adults much more commonly than children. Pubic lice cannot survive for very long away from the warmth and humidity of a human body. Experts say that crabs are the most contagious STD (sexually transmitted disease).

Crabs can be treated without needing to go to see a doctor. There are pubic crabs treatment creams, lotions and shampoos available at pharmacies which do not require a doctor’s prescription.

Anybody with an infestation should also make sure that other people who came into close physical contact receive treatment; including all members of the household, not just sexual partners. In the majority of cases, the first pubic crabs treatment will be successful and all the lice will be killed off. However, the nits may still be there, with the risk of hatching. If you re-apply the medication after seven days it makes sure that any hatched lice will be killed off before they are mature enough to reproduce.
