What Are Pubic Lice (Crabs)?
Pubic lice, commonly known as crabs, are tiny insects that infest the hair in the pubic area. They are usually spread through sexual contact. The louse that causes the infestation is called Pthirus pubis.
Although they are most common in pubic hair, they can also be found in other coarse body hair, such as hair on the legs, armpits, chest, and even eyebrows and eyelashes.
Symptoms
The main symptom is intense itching in the genital region. Other signs include:
- Seeing live lice or nits (tiny, oval-shaped eggs) attached to pubic hairs.
- Small blue spots on the skin where the lice have been biting.
- Fine, dark powder in your underwear from the lice droppings.
Treatment for Pubic Lice
Pubic lice are treated with over-the-counter or prescription medicated lotions and shampoos (pediculicides). Our doctors can advise on the best product.
- The treatment is applied to the affected areas and washed off after a specified time.
- A fine-toothed comb may be used to remove nits from the hair shafts.
It is important to wash all clothing, bedding, and towels in hot water and dry them on a high heat setting. Sexual partners should also be treated. You should avoid sexual contact until the infestation has cleared.
