If you become infected with crab lice, you will want to treat the condition right away. Leaving crab lice untreated will allow the crab lice to multiply, possibly causing re-infection and/or the infection of those closest to you. Here is a look at the steps you will need to take to treat crab lice.
Two to three days before treatment, you will need to wash bedding, clothing, linens, and other washable items that the infested person has used. You will need to use the hot water cycle on the wash, making sure that the water gets to at least 130 degrees Fahrenheit during the cycle. Dry the clothes on the hot cycle of the dryer for at least 20 minutes.
Dry clean any clothing that cannot be washed in hot water.
Wash. You will need to thoroughly wash all infested areas (Remember, crab lice can live on armpit hair, facial hair, and leg hair, as well as on pubic hair). Pat dry with a towel.
Saturate the hair with lice medication. Read the manufacturer’s instructions as to how long you need to leave the medication on for. In general, permethrin and pyrethrin medications need to be left on for 10 minutes, while Lindane should be left on for 4. Rinse off with water and pat dry with a new, clean towel.
After treatment, you will need to remove nits. Most crab lice treatments will not kill the nits. Nits can be removed with the fingernails or a special nit comb.
Dress in clean underwear and clothing.
You will want to inform any sexual partners that they are at a risk of infection. They may want to do a crab lice treatment as a precaution against infection, as well as wash any potentially contaminated clothing, bedding, and other linens
Avoid sexual contact until both partners have been treated and the infestation of crab lice has been cured. Multiple treatments may be needed to completely eradicate the infestation
Retreat as needed. It takes 7-10 days for any nits to hatch, at which point the new adults will need to be treated to prevent further infestation.
Large items that cannot be washed should be placed into a plastic bag and tightly sealed. The bag should then be stored for at least 2 weeks. Adult crab lice cannot live without a host for longer than 2 days, and the additional time will kill off any new crab lice that might hatch from already laid nits.
If you continue to see crab lice, you may need to consult your doctor for assistance and treatment.
Crab lice treatment near the eyes
If there is an infestation of crab lice on the eyebrows or eyelashes, do not use chemical crab lice treatments, as these could cause irritation and damage to the eyes. If only a few nits are seen, you can try removing them with your fingernails or a nit comb. If this is unsuccessful at eliminating the infestation, you will need to make an appointment with your doctor. A treatment of prescription ophthalmic-grade petrolatum will usually prove effective. All other crab lice treatment of the environment should be followed as well.
