Pubic Lice

Pubic lice, also known as crabs, are mainly found in the pubic and perianal areas, but can also live in the eyebrows, eyelashes, chest hair, facial hair and armpit hair.

Female lice lay their eggs (also called nits) at the base of the hair shaft. Without a human host, adult pubic lice typically survive no longer than 24 to 48 hours, while their eggs (nits) can live no longer than a few days.

Pubic lice differ from head lice. Pubic lice are small insects that look like crabs. A pubic louse measures between 1 and 3 mm, has a broad body and powerful legs that look like claws. It is gray-brown in color.

Symptoms

Pubic lice can be uncomfortable, but rarely pose a serious health risk. Their bites can leave small bluish marks on the skin. People with pubic lice may experience itching, which often worsens at night. This is due to an allergic reaction to the bites.

Cause

Pubic lice are primarily transmitted through sexual contact. Transmission is also possible through infested objects such as clothing and bedding.

Pets can't get or spread pubic lice.

Treatment

Treatment involves applying pediculicide (treatment against lice) to the affected areas. These products are available at pharmacies without a prescription. However, eyelashes and eyebrows must be treated differently. It is important to follow your health care provider's directions and recommendations.

It is recommended to also treat sexual partners from the past 30 days. Avoid intimate relations until the end of treatment and the disappearance of symptoms.

Along with the treatment, clothing and bedding should be washed in very hot water, dry-cleaned, or tumble-dried on a high-heat setting for about 30 minutes. Objects that are difficult to wash can be placed in hermetically sealed bags for a minimum of 2 weeks. A thorough vacuuming of the house is also recommended.
