Pubic lice, also known as crabs, are tiny insects (about 2mm long) that live on coarse human body hair, such as pubic hair. Pubic lice are not linked to poor personal hygiene.
The most common way to get pubic lice is through sexual activity. In children, pubic lice may be found in the eyebrows or eyelashes and can be a sign of sexual abuse. However, it may be possible to catch pubic lice after sharing clothing, bedsheets or towels with an infected person.
Pubic lice are mainly spread by close body contact, most commonly sexual contact. The lice cannot jump or fly, but can climb from one person to another. You can also catch the lice from clothes, bedding or towels used by someone with pubic lice, but this is rare.
Pubic lice infestations (pthiriasis) are usually spread through sexual contact. Dogs, cats, and other pets do not play a role in the transmission of human pubic lice. Both over-the-counter and prescription medications are available for treatment of pubic lice infestations.
How you can get pubic lice. Pubic lice are typically transmitted through intimate contact, including sexual intercourse.

Pubic lice and their eggs attach very strongly to hair; they won't wash or brush off, nor do they fall off. They cannot survive for long without a human 'host' to feed from. This means that you are very unlikely to catch pubic lice from clothing, bed linen, shared towels or toilet seats.
How do you get pubic lice? It can take up to 3 weeks after coming into contact with pubic lice before you notice any symptoms. They are spread through close body contact with someone who has them, most commonly sexual contact. The lice crawl from hair to hair but can't fly or jump.
