Pubic Lice

Pubic lice, often called crabs, are tiny parasitic insects that live on human body hair, such as pubic hair.

Most common symptoms

  • Itching, irritation and inflammation in the affected areas.
  • Sky-blue spots or very tiny specks of blood on the skin.

Symptoms

Men and women – 

  • Itching, irritation and inflammation in the affected areas,
  • Black powdery droppings from the lice in your underwear,
  • Brown eggs on pubic hair or other body hair,
  • Sky-blue spots or very tiny specks of blood on the skin

It can take several weeks after coming into contact with pubic lice before signs and symptoms appear

What does a check-up/test involve?

Pubic lice is often diagnosed by how it looks so be prepared to drop your pants so the doctor or nurse can take a look at the infection and decide on what treatment is best for you.

Treatment

Treating crabs involves using a special cream, lotion or shampoo which can be purchased over the counter from a pharmacy. To be effective, treatment needs to be repeated after three to seven days.

You should wash your clothing, bedding and towels in a washing machine on a very hot cycle (50°C or higher) to kill the lice and avoid re-infection. Even after successful treatment, itching may continue for a few days. There may be nits in your body hair after treatment but these can be removed with a special comb that you can get over the counter from a pharmacy.

If left untreated?

If left untreated, you can develop infections from scratching. It can also cause your skin to change colour and become scaly and scarred.
