Crab lice, also known as pubic lice, are a type of external parasite that infests human pubic hair, causing discomfort, itching, and embarrassment. Understanding the facts about crab lice is essential for effective removal and prevention of future infestations. In this article, we will delve into 12 crucial facts about crab lice, providing you with the knowledge needed to tackle this pesky problem.
Introduction to Crab Lice
Crab lice are tiny, flat, and oval-shaped insects that feed on human blood. They are usually found in the pubic area but can also infest other areas with coarse hair, such as the armpits, beard, and eyebrows. Crab lice are highly contagious and can be spread through direct contact with an infected person, sharing of personal items, or contact with contaminated bedding or towels. It is essential to take prompt action when dealing with crab lice to prevent further infestation and alleviate symptoms.

The life cycle of crab lice consists of three stages: egg, nymph, and adult. Eggs are usually laid on the hair shaft and take about 6-10 days to hatch. The nymph stage lasts around 2-3 weeks, during which the lice molt several times before reaching adulthood. Adult crab lice can live for up to 30 days, feeding on human blood and causing discomfort. Understanding the life cycle of crab lice is crucial for effective removal and prevention of future infestations.

Prescription treatments such as ivermectin or spinosad may be necessary for more severe infestations or in cases where over-the-counter medications are not effective.
Environmental Cleaning
Environmental cleaning is crucial in preventing re-infestation of crab lice. It is essential to wash and dry clothing, bedding, and towels in hot water, and to dry-clean or seal in a plastic bag any items that cannot be washed. Vacuuming carpets and upholstered furniture can also help remove any lice or eggs that may have fallen off the infested person.
Here are some additional tips for treating and removing crab lice:
- Use a fine-tooth comb or a specialized lice comb to remove lice and eggs from the hair.
- Wash the infested area with soap and water, and dry thoroughly.
