Pubic lice, also called crabs, are small but visible insects that inhabit genital area. These lice differ from those found in head and body.
These lice have bodies similar to that of tiny crabs, hence the name crabs. They are usually transmitted through sexual contact. However, they can also spread by sharing contaminated clothing, bed linens or towels.
If you observe pubic lice in children’s eyebrows or eyelashes, you may suspect cases of sexual abuse. Pubic lice survives on your blood and sucks the blood out by biting your skin.
These bites can result in severe itching. Various nonprescription creams and lotions to kill the parasites and their eggs are available in the market.
The most common symptom of having pubic lice is severe itching in your genital area. As the lice can infest other parts like legs, chest, armpits, beard, eyelashes or eyebrows, it can also cause irritation and itching on these affected areas too.
