Pubic lice causes itching in the area covered by pubic hair. Itching often gets worse at night. The itching may start soon after getting infected with lice, or it may not start for up to 2 - 4 weeks after contact.
Other symptoms can include:
►Skin reaction that causes skin to turn bluish-gray in color
►Sores in the genital area due to bites and scratching
Exams and Tests:
The health care provider will do an exam to look for:

Because pubic lice may cause an eye infection (blepharitis) in young children, eyelashes should be viewed with a high-powered magnifying glass.
Adult lice may be easily identified under the microscope. Pubic lice are often referred to as "the crabs" because of their appearance.
Teenagers with pubic lice may need to be tested for other sexually transmitted infections (STIs).
