So, the realistic answer is “No, you can't drown lice.” The best treatment for lice is to get them picked out by a professional – Lice Geeks, for example – using the right comb. Even over-the-counter shampoos and products aren't as effective as a well-trained professional wielding the proper comb.
Why can't you drown them by taking a long bath or going for a swim? Lice have evolved with humans, and we have always put our heads in water. They are designed to resist it. The louse shuts itself down, it is called sham death, and when you take it out of the water it recovers within five minutes.
Permethrin lotion, 1%;
Permethrin lotion 1% is approved by the FDA for the treatment of head lice. Permethrin is safe and effective when used as directed. Permethrin kills live lice but not unhatched eggs. Permethrin may continue to kill newly hatched lice for several days after treatment.
Lice are also tenacious and can't be killed with a hot shower or strong shampoo. If you find evidence of lice treat all members of the household. Also, wash linens and towels on a hot setting of the washing machine.
Can swimming spread lice? Data show that head lice can survive under water for several hours but are unlikely to be spread by the water in a swimming pool. Head lice have been seen to hold tightly to human hair and not let go when submerged under water. Chlorine levels found in pool water do not kill head lice.
Washing, soaking, or drying items at a temperature greater than 130°F can kill both head lice and nits.
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.
Lice and nits can't survive the high heat. It's true that lice and nits can't survive temperatures above 113°F (45°C). This makes them susceptible to any heat source, such as a hairdryer or the plates of a hair straightener.
Dehydration: Applying hot air with a special machine operated by a professional can cause dehydration, possibly killing the eggs and lice. Household cleaning: Lice usually can't live more than a day without feeding off a human scalp, and the eggs can't survive if they aren't incubated at the temperature in the scalp.
Either washing done with a water temperature of at least 50 degrees C or drying is necessary to kill head lice and nits.
They found vinegar was actually the least effective treatment method for getting rid of lice or suppressing the hatching of nits. Vinegar wasn't the only home remedy that didn't do well. No home treatment prevented lice from laying eggs. Even with prolonged exposure, most home remedies were unable to kill nits.
Can vinegar kill lice eggs? Vinegar is one of the classic home remedies for lice. However, if you are trying to find out how to get rid of nits using vinegar, you should know that using vinegar to kill nits or lice eggs is totally ineffective. Vinegar has no negative effect on the lice eggs.
If you try to drown lice, you would need to keep them submerged for more than 8 straight hours in order to ensure they have indeed drowned. No coming up for air. Adult lice can “hold their breath” for up to 8 hours – they close their air holes and stay where they are until they can breathe again.
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.
Lice and nits can be removed by wet combing. You should try this method first. You can buy a special fine-toothed comb (detection comb) online or from pharmacies to remove head lice and nits.
If you begin to find that the nits are further away from the scalp, they may not be viable. Using a magnifying lens will make it easier to search for nits close to the scalp. You'll want to make sure that there are no clusters of nits close to your child's scalp for at least two weeks before you are in the clear.
The conditioner does not kill lice but stuns them for about 20 minutes enabling easier removal. The long toothed metal comb will remove nits and the stunned head lice. Wipe the comb on a white tissue and check for any lice or nits. Keep combing until no more appear on the tissue.
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.
Hair gels, hairspray, oils or other non-medicated hair products including dandruff shampoo will not kill lice or prevent eggs from hatching or sticking to the hair.
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.
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.
Petroleum jelly (Vaseline).
The thick jelly supposedly suffocates lice by clogging their breathing holes. For best results, coat the hair and scalp, cover it overnight with a shower cap, and wash out the next morning. Comb for nits. Repeat the treatment one week later.
Avoid sleeping in the same bed as the person with an active lice infestation. Avoid sitting where the person with lice has sat in the past two days. Wash linens and clothing in hot water and dry on high heat. Place stuffed animals, pillows and items that cannot be washed into an airtight bag for two weeks.
First, wash the hair with a regular shampoo. Then, towel dry it before using the anti-lice creme. Do not use a conditioner or creme rinse after shampooing. Reason: It will interfere with Nix.
