If you have pubic lice (crabs), you may experience intense itching in your genital region. Pubic lice don't infest the scalp, but they can spread to other areas with coarse body hair, including the:

  • Legs
  • Chest
  • Armpits
  • Beard or mustache
  • Eyelashes or eyebrows, more commonly in children

When to see a doctor

Seek medical advice about pubic lice treatment if:

  • Over-the-counter products don't kill the lice
  • You're pregnant
  • You have any infected skin abrasions from scratching
