PUBIC LICE (CRABS)

What are Pubic Lice?

Pubic lice, also called “crabs,” are tiny insects that live on coarse human hair, most commonly in the pubic area. They feed on blood and can cause itching and irritation. Pubic lice are spread primarily through close physical contact, including sexual contact, but can also be transmitted through infested clothing, towels, or bedding.

Symptoms

Pubic lice can cause noticeable symptoms, though some people may not realize they are infested at first. Symptoms usually appear within 5–10 days after contact with someone who has lice. They may include:

  • Itching in the genital area or other areas with coarse hair

  • Red or blue spots on the skin where lice have bitten

  • Visible lice or tiny eggs (nits) attached to hair shafts

  • Irritation or inflammation from scratching

How Can I Get Tested for Pubic Lice?

Pubic lice can be treated with over-the-counter or prescription insecticidal creams or shampoos. Wash clothing, bedding, and towels in hot water to prevent re-infestation. Sexual partners may also need to be treated to avoid passing lice back and forth.
