While heat does kill lice on clothes, you don't need to boil the items to get rid of lice on clothes. Simply washing the items in hot water and drying them at a high temperature should get rid of the critters.
Either washing done with a water temperature of at least 50 degrees C or drying is necessary to kill head lice and nits.
Getting rid of body lice
Lice and eggs in clothing will die if the clothes are not used. All stages that are not in contact with the body, except the eggs, will die within 1-2 days at ambient temperature.
Washing, soaking, or drying items at a temperature greater than 130°F can kill both head lice and nits. Dry cleaning also kills head lice and nits. Only items that have been in contact with the head of the infested person in the 48 hours before treatment should be considered for cleaning.
After each treatment, checking the hair and combing with a nit comb to remove nits and lice every 2–3 days may decrease the chance of self–reinfestation. Continue to check for 2–3 weeks to be sure all lice and nits are gone.
Ivermectin (Sklice).
This lotion kills most head lice, even just-hatched lice, with just one use. You don't need to comb out lice eggs (nits). Children ages 6 months and older can use this product.
Repeat treatment every day or every other day for 2 weeks. Some lice eggs (nits) survive head lice treatments. The only way to be sure that lice won't come back is to pick out all nits. Nits left on the hair can hatch and cause a new case of head lice.
There are recent studies that show that treatment of lice with heat can be quite effective in killing head lice. Products such as Lousebuster are very effective but even a home hairdryer can successfully treat lice.
The risk of getting infested by a louse that has fallen onto a carpet or furniture is very small. Head lice survive less than 1–2 days if they fall off a person and cannot feed; nits cannot hatch and usually die within a week if they are not kept at the same temperature as that found close to the scalp.
Adult lice can't live longer than 24 hours or so on nonhuman surfaces like carpets, hardwood floors, clothing, furniture, sports helmets, headphones, or hair accessories. However, if you have identified lice in your home, isolate and wash those items and areas within at least 72 hours.
Wash items on a hot water cycle and dry on high heat for at least twenty minutes. The heated wash and dry will remove and kill any lice left. Carpets, mattresses, and flooring can simply be vacuumed and cleaned with everyday cleaning products.
There is no need for special chemicals or detergents to kill the lice. You don't need any unusual equipment or special training. The primary weapon against these bugs is… heat.
Vinegar contains properties that kill and get rid of nits and lice. This mixture should be applied directly to the whole scalp. Mix 1 cup of vinegar with 1 cup of warm water. Next, distribute this mixture onto the scalp and cover your hair with a hair cap.
Just like with mattresses, lice can only live on any bedding—whether it's sheets, pillows, or comforters—for 1-2 days. Without a human scalp as a source for food (blood) for longer than 1-2 days, lice cannot survive.
As head lice can live on pillows, you'll need to clean them. Adult lice can only survive for two days without a host. However, they can still lay eggs. If the infected person has had a lice treatment and then picks up stray lice from their pillow, the lice infestation cycle can start all over again.
Clean all hair items by soaking in a lice treatment product for 10 minutes or cleaning with hot, soapy, or boiling water for 5 minutes. Never share towels, bedding, clothing, hats, and headgear. thoroughly. Insecticide sprays are not recommended because this will expose household members to unnecessary pesticides.
It's rare for head lice infestations to spread through the common use of furniture or carpets, but it's a good idea to do some post-infestation housework. Toss pillows and mattress pads in the washing machine, and use the hand tools on your vacuum cleaner to thoroughly clean mattresses, furniture, and car seats.
Hairspray makes it harder for the louse to grab hold. The smell of hairspray and the use of solvents (sad but true) in them can also deter creepy crawlies from finding their way in. Not to mention that if you're tying longer hair back, you've got a double whammy.
Typically, 10–15 head lice are found. The number of lice often depends on personal hygiene, for example, how often the person bathes, shampoos, or changes and washes his/her clothing.
Do not use a conditioner. It can keep the lice medicine from working. Rinse well with warm water and towel dry. Do not use the towel again until it has been laundered.
Tea tree oil appears to be able to kill some live lice (at least when used in conjunction with lavender oil), however we know that over-the-counter lice treatments are far more effective at killing live lice and getting rid of the eggs once an infestation has occurred.
Use fingers to separate hair and create a part. The part should allow you to clearly see the person's scalp. Look for lice crawling on the scalp where the hair is parted or on the hair shaft. The lice will be dark in color and the size of a poppyseed.
Environmentally relevant levels of pyrethroids—the class of pesticide that includes Permethrin—are also common in some household insecticide products. This means that adding lice shampoo, even the amount directed, to the level of pyrethroids already in a home can overexpose children to the pesticide.
Generally, if no live crawling insects are seen three weeks after the treatment, it's safe to assume that they are gone. Nits would have hatched by that time if they were alive. Nits and their shells may remain in the hair for some time but won't be viable.
Parents must be careful not to overuse a prescription drug for treating lice infestations because too much could cause neurological damage, the Food and Drug Administration said yesterday. The drug, lindane, is safe when used as directed, the FDA said.
