What are skin crabs?

"Skin crabs" is a colloquial term often used to refer to pubic lice, scientifically known as Pthirus pubis. These tiny parasitic insects infest coarse body hair, particularly in the pubic region, but can also be found in other areas like the armpits or facial hair. They are typically transmitted through close physical contact, including sexual activity, and can cause itching and irritation. Treatment usually involves topical insecticides or over-the-counter remedies.
