What are pubic lice?
Pubic lice are small, parasitic insects that typically live in the pubic area or other areas of the body that have coarse hair, such as the armpit, beard, eyebrows or eyelashes. They have three forms: nits, which are eggs; nymphs, which are immature lice; and adults. The scientific name for pubic lice is Phthirus pubis, but they are frequently referred to as “crabs” due to their large front legs that resemble crab claws.
Sexual Health Spotlight
Although pubic lice can be spread to close personal contacts through clothing, towels and linens, they are most commonly spread through sexual contact. Nymphs and adults must feed on human blood and do not survive more than a day or two without access to it. Animals do not carry or spread pubic lice.
Itching is the most common symptom of pubic lice, although it may not start for two to four weeks after exposure. Nits may be seen as small whitish-gray oval eggs attached to the hair. Adult lice may be seen crawling through the hair. Multiple small scabs may be present from scratching.
Over-the-counter lice-killing medications are available and are often enough to treat pubic lice. If these are not successful, prescription medications can be used. After treatment, any remaining nits should be removed with the fingernails or a fine-tooth comb. Also, all clothing, towels and linens should be washed and dried on hot settings, dry cleaned, or sealed in plastic for two weeks.
If over-the-counter medications are not successful in treating the pubic lice or if you have symptoms of pubic lice but do not see any nits or crawling lice, seek prompt medical care. Since lice-killing medications should not be used near the eyes, if you have lice in the eyelashes that you cannot remove, you should also seek prompt medical care. This is also true if you have any sores that produce pus or don't heal. Regardless of the success of treatment, if you have pubic lice, you should contact your health care provider to be evaluated for any sexually transmitted infection that may have been spread at the same time as the pubic lice.
