When you suspect your crabs may have head lice, the first sign you will notice is intense itching and scratching. You may also notice nits on your hair. In severe cases, the itching can be so bad that it could cause secondary bacterial infections. You should immediately wash bedding, clothing, and towels in hot water.
Fortunately, there are several effective treatments for head lice. Some are over-the-counter and some are prescription-only. The main goal of these treatments is to kill lice and their eggs. However, some lice are resistant to these treatments, so be sure to talk to your doctor to find the best solution for you.
Over-the-counter head lice products contain compounds that kill crabs. Pyrethrum extracts and permethrin are common ingredients in such products. They are sold under brand names such as RID and Nix. Specially-formulated products for pregnant women are also available. Another option is to use a nit comb, which you can buy at a drug store.
You should also treat yourself and other members of your family with lice treatment. It is important to use a permethrin-containing product. You should not engage in sexual activity until after the treatment. You should also get a medical examination to rule out any STDs or other infections.
