Pubic
Usually, pubic lice live on pubic hair in the genital area. If you look carefully, you may be able to see visible nits or crawling lice. Less commonly, they live on hair on other parts of your body. This may include legs, armpits, beard, eyebrows, eyelashes, or on your head.
The most common symptom of pubic lice is itchy red spots. The itching is caused by an allergy to the louse saliva or poo. It can take 1 to 3 weeks for itching to develop after the first infestation, and it'll usually be worse at night. Adult pubic lice are tiny – smaller than a match head.
If you have pubic lice (crabs), you may experience intense itching in your genital region. Pubic lice can spread to other areas with coarse body hair, including the: Legs. Chest.
Pubic lice are small, crab‑like insects that are grey or brown‑red. They live in pubic hair, but can be on other body parts with hair (like the chest, armpit, face, eyelashes). Crabs can live for up to 24 hours on bedding, towels, and clothes.
They hatch after 7-8 days. Over the next 13 to 17 days the larvae will change skin three times before reaching adulthood. Adult lice live for just under a month. Pubic lice can only survive and reproduce on people.
A lice-killing lotion containing 1% permethrin or a mousse containing pyrethrins and piperonyl butoxide can be used to treat pubic (“crab”) lice. These products are available over-the-counter without a prescription at a local drug store or pharmacy.
It should be explained that pubic lice infection does not go away on its own and needs therapy. It may be passed on to others if not treated adequately. In addition pubic lice infestation does not carry the risk of transmitting STIs or HIV from one person to another.
Animals cannot get or spread pubic lice. If left untreated, the affected area will continue to itch. Repeated scratching of the infested area can result in other serious skin infections.
You cannot get rid of pubic lice by washing or shaving, as the lice only need a minimal length of hair on which to lay their eggs. Therefore you do not need to shave your pubic hair. You can treat yourself at home with an insecticidal lotion or cream which is available over the counter from a pharmacy.
The lice cannot jump or fly, but can climb from one person to another. You can also catch the lice from clothes, bedding or towels used by someone with pubic lice, but this is rare.
A common misunderstanding is that infestation can be spread by sitting on a toilet seat. This isn't likely, since lice cannot survive away from a warm human body. Also, lice do not have feet designed to walk or hold onto smooth surfaces such as toilet seats.
Pubic lice (Pthirus pubis) have three stages: egg, nymph and adult. Eggs (nits) are laid on a hair shaft . Females will lay approximately 30 eggs during their 3–4 week life span. Eggs hatch after about a week and become nymphs, which look like smaller versions of the adults.
Are pubic lice dangerous? No, pubic lice won't cause serious health concerns. Usually, the main problems that the lice cause are itching and discomfort. You may get a bacterial infection if you end up scratching your skin a lot.
Usually, the symptoms of pubic lice start about 5 days after you get them. Some people never have symptoms, or they think the symptoms are caused by something else (like a rash). The most common symptom of pubic lice is intense itching in your pubic area.
Can head lice and nits live on pillows or sheets? Lice and nits can live on pillows and sheets. Lice glue their eggs to the hair strands of their host. However, if a piece of hair with an egg falls out while the lice host is sleeping, an egg could end up on pillows or sheets.
Applying topical creams or lotions containing permethrin (for example, Lyclear cream or Quellada lotion) to the whole body from neck to toes is the most commonly recommended treatment. You do not need to apply the cream to the hair on your head. See your doctor, pharmacist or sexual health centre for further advice.
You may see one or more lice or nits in your pubic hair. The nits look like tiny white dots attached to a hair. They look like dandruff. Dandruff, however, is easily brushed out of the hair.
Getting pubic lice doesn't mean you're dirty — it has nothing to do with hygiene or cleanliness. Anybody can get pubic lice if they have close, personal contact with someone who has them. About 3 million people in the U.S. get pubic lice every year.
Adult lice are gray-brown and about 1.1–1.8 millimeters long. A person may be able to see them with the naked eye. The eggs and immature lice are smaller, however, and they may not be visible without a magnifying glass.
Can head lice live on pillows or sheets? Head lice cannot live for long on pillows or sheets. It is possible for a live louse that has come off a person's head to crawl onto another human host who also puts their head on the same pillows or sheets.
As with furniture and carpets, adult lice typically live for around 2 days on pillows and sheets without human contact. Nits will not hatch and will die within a week. People should machine wash any pillows or sheets someone with lice has used in hot water of more than 130°F (54.4°C) .
About 3.3 million years ago, lice found on gorillas began to infest humans, Reed said. That they took up residence in the pubic region may have coincided with humans' loss of hair on the rest of their bodies and the lack of any other suitable niche, he said.
