Pubic Lice

The photo shows pubic lice in the pubic hair of groin area. Pubic lice are tiny wingless insects that live only on human beings. The are also called "crabs".

Typical symptoms of pubic lice are:

  • Itching of the pubic area is the main symptom.
  • Pubic hair contains gray bugs (lice) 1/16-inch long, that move quickly, and are difficult to see.
  • Nits (white or tan eggs) cemented to hair shafts near the skin (usually within 1/2 inch or 12 mm). Unlike dandruff or sand, nits can't be shaken off the hair shafts.

Pubic lice are very contagious:

  • The primary mode of transmission is via the skin-to-skin contact that occurs during sexual intercourse. There is a 95% chance of transmission during a single episode of sexual intercourse.
  • Rarely they can be transmitted via objects such as infected bed linens or toilet seats.
