Noticing an unexpected itch in your pubic area can be worrying. If the irritation persists, you might start to wonder if something more than just dry skin is causing it. One common possibility is an infestation of pubic lice, often referred to as “crabs.” Knowing what to look for is the first step toward addressing the issue.
Pubic lice are tiny insects that live in coarse body hair, most commonly in the pubic region. They are a type of parasite, meaning they survive by feeding on human blood. While the thought can be unsettling, it’s a very treatable condition, and identifying it early can help you find relief quickly.
Identifying Pubic Lice and Their Eggs
So, what exactly are you looking for? Adult pubic lice are incredibly small, about the size of a pinhead (1-2 millimeters). They are tan or grayish-white in color, but they can appear darker after feeding. Their bodies are broad and crab-like, which is where their nickname comes from. You might spot them moving, but they often stay still, holding tightly onto the hair shaft.
You are more likely to see their eggs, called nits. Nits are tiny, oval-shaped, and yellowish-white. They are firmly attached to the base of pubic hairs and can be difficult to remove. You may also notice small, dark blue or black spots on your skin or underwear; this is louse droppings. Another sign is the appearance of small, blue-gray spots on the skin where the lice have been feeding.
Common Signs of an Infestation
Often, the symptoms will alert you before you see the lice themselves. The most common sign is intense itching in the pubic area, which is caused by an allergic reaction to the louse bites. This itching usually starts about five days after the initial infestation. You might also experience inflammation or small red bumps from scratching, which can sometimes lead to a secondary bacterial infection if the skin is broken.
How to Check for Pubic Lice
If you suspect you have pubic lice, a simple visual inspection can help confirm it. Use a bright light and a magnifying glass to examine the hair at the base of the skin. Look for moving lice and the small, cemented nits attached to the hair shafts. Remember, nits will not flick away like lint or dandruff; they are glued on.
Finding Effective Treatment and Relief
The good news is that pubic lice are easily treated with over-the-counter or prescription medications. These usually come in the form of a lotion or shampoo containing permethrin or pyrethrin. It is crucial to follow the package directions exactly and to treat all affected areas. Because lice can live for a short time on clothing and bedding, you should also wash all clothes, towels, and bed linens in hot water and dry them on a high heat cycle to prevent re-infestation.
Noticing signs of pubic lice can be embarrassing, but it’s a very common issue that has nothing to do with personal hygiene. These parasites are spread through close physical contact. By accurately identifying the problem, you can take the right steps to treat it effectively and get back to feeling comfortable.
