Shaving your pubic hair, whilst it might make you feel better, does not get rid of the crabs but does remove their eggs. The crabs will cling on to you and crawl to other body hair. If you do decide to shave, do it a long while after you have applied the lotion.
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.
Shaving Will Not Get Rid of Lice.
The reason shaving will not work is because lice live on the base of the hair, and on the scalp. The nits are laid right at the base of the hair oftentimes against the scalp. Shaving will not get close enough to make an impact on the lice and nits.
Treatment for pubic lice
The main treatments for pubic lice are medicated creams or shampoos that kill the lice. You usually need to use the treatment on your whole body and leave it on for a few hours before washing it off. You'll need to repeat this again a week later to make sure all the lice have been killed.
They can also be spread through contact with the clothing and bedding of someone with crabs. 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.
Life Cycle:
Pubic lice (Pthirus pubis) have three stages: egg, nymph and adult.
Symptoms include itching in the genital area and visible nits (lice eggs) or crawling lice. How soon do symptoms appear after exposure? People do not usually get any symptoms until they have had pubic lice for about 5 days. Some people never get symptoms.
Pubic lice don't live on other animals such as cats or dogs. It's also possible for pubic lice to be spread through sharing clothes, towels and bedding.
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.
However, can shaving or waxing one's pubic hair treat an existing pubic-lice infestation? It might seem plausible, but the CDC, Planned Parenthood, and other health authorities don't recommend it. Pubic lice (and their eggs) are treated with a topical medication, and it might be necessary to apply it from neck to toe.
Benzyl alcohol lotion, 5% has been approved by the FDA for the treatment of head lice and is considered safe and effective when used as directed. It kills lice but it is not ovicidal. A second treatment is needed 7 days after the first treatment to kill any newly hatched lice before they can produce new eggs.
A lice-killing lotion containing 1% permethrin or a mousse containing pyrethrins and piperonyl butoxide can be used to treat pubic (“crab”) lice.
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.
Although pubic lice and nits can be large enough to be seen with the naked eye, a magnifying lens may be necessary to find lice or eggs.
The lice bites become crusty or filled with pus, or your skin has a bad smell.
Pubic lice can survive in bedding but not for very long.
Itchy pubic hair is common and is often easily treatable. Common causes include rash burn, contact dermatitis, jock itch, pubic lice, scabies, yeast infection, psoriasis, eczema, and folliculitis. See a healthcare provider if the itching is severe, painful, persistent, or worsening. American Academy of Dermatology.
Pubic lice affect men and women at all levels of society all over the world. Teens and people in their 20s are most often affected. But children and older adults can also get pubic lice. Some studies are showing pubic lice cases are decreasing because of genital hair removal techniques like waxing.
Common signs and symptoms of lice include: Intense itching on the scalp, body or in the genital area. A tickling feeling from movement of hair. The presence of lice on your scalp, body, clothing, or pubic or other body hair.
Pubic lice feed on your blood, and their bites can cause severe itching. Treatment includes applying over-the-counter creams and lotions that kill the parasites and their eggs.
Crabs can live for up to 24 hours on bedding, towels, and clothes. They feed on the blood of the infected person (by taking small bites that can cause itching).
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.
