Causes

By Mayo Clinic staff

Pubic lice are different from the lice found in a head or body lice infestation. Pubic lice infestations are caused by exposure to pubic lice or their eggs through:

  • Sexual activity. A pubic lice infestation is most commonly caused by transmission of lice during sexual activity. If exposed to pubic lice during sex even once, you are more than 90 percent likely to get an infestation.
  • Contaminated objects. Although rare, you may also acquire pubic lice from contaminated sheets, blankets, towels or clothes. It's possible to be exposed while trying on bathing suits when shopping. Young children exposed to heavily infested adults may develop a pubic lice infestation in their eyelashes and eyebrows.
