Vaseline (petroleum jelly) can help kill some adult lice and eggs by suffocating them, but it's messy, hard to wash out, and not a foolproof treatment as some eggs may still hatch, requiring diligent, repeated combing and potentially professional pediculicides. While some studies show it kills most lice, others suggest it's better to use doctor-recommended medicated shampoos for guaranteed effectiveness, especially with stubborn infestations, notes WebMD, the NIH, and the American Academy of Dermatology.
While Vaseline is one of the more effective home remedies, it's not foolproof. One study found petroleum jelly stops all but 6% of nits from hatching and can kill a lot of lice – but it won't stop the surviving lice from laying more eggs.
Use heat. Wash any items used or worn by the person in hot water, and dry them on high heat. Lice and nits die when exposed to temperatures higher than 130 F for more than 5 minutes.
Results indicated that only the application of petroleum jelly caused significant louse mortality but no treatment prevented lice from laying eggs. Most home remedy products did little to kill eggs, despite prolonged exposure.
The Ancient Egyptian
Remedies for the common person included eating a special meal mixture with warm water, and then vomiting it up. Others believed a recipe of spices mixed with vinegar rubbed on the scalp over a few days would suffocate them out. For royalty and priests, their heads were no exception.
Getting head lice isn't a sign of poor hygiene or unclean surroundings. Head lice prefer clean hair to attach and lay their eggs. Another common misconception is that head lice can jump or fly from one person to another. Head lice only crawl, most often leading to transmission through direct head-to-head contact.
Head lice infestation is most often caused by direct contact with these insects. Head lice are a tan or gray insect about the size of a sesame seed. The female louse sticks each egg to the base of a hair shaft less than 1/8 inch (3 millimeters) from the scalp.
Smothering agents
Some people use household products to keep head lice from getting air. These products include mayonnaise, margarine or butter, or petroleum jelly. People put a lot of the product on the hair, cover the head with a shower cap and leave it on overnight.
Lice dislike the smell of many things, but the thing they hate most is peppermint. So, before you send your kid off to hang out with other kids, spray them with a peppermint spray. It's the same concept as using a mosquito or bug spray in the summer months, except the scent is less offensive.
These tiny insects infested clothing, irritated skin and caused 'trench fever' and typhus. Men in the trenches killed lice by 'chatting' - crushing them between finger nails - or burning them out with cigarette ends and candles.
Common black bugs found in hair besides lice include fleas, bed bugs, gnats, and other small flying insects. Each has distinct characteristics and requires different treatment approaches.
Yes, head lice can briefly live and crawl onto pillows, but they can't survive long (usually 1-2 days) without a human host for blood meals, and nits won't hatch without scalp warmth, making pillows a low risk for infestation, but washing bedding in hot water is recommended to kill any stragglers.
As far as DIY hair treatments go, Vaseline isn't too bad. There are no known side effects of using Vaseline for your hair. But it's a greasy substance, so it may cause your hair to feel heavier and oiler. If you use Vaseline on your scalp, it can cause build-up.
Some of the less riskier attempts have included using cooking oil, mayonnaise, Vasoline jelly, Vicks Vaporub and vinegar. Unfortunately, research has shown that these lice can survive quite well covered with these products, even when left on overnight. Regular shampooing won't work either.
Head lice eggs (aka nits) are coated in a special protective, waxy coating that functions as a waterproofing agent. So if you apply Listerine to your head, it may loosen up the glue that binds nits to your strands of hair a little, but not enough. And it certainly won't kill them.
(Phthiraptera: Pediculidae), on feeding success, longevity and numbers of eggs laid were investigated using an artificial blood-feeding system in the laboratory. No significant differences were found between lice fed on different human blood types for any of the parameters tested.
Smothering agents: There are several common home products that may kill lice by depriving them of air and smothering them. These products include petroleum jelly (Vaseline), olive oil, butter, or mayonnaise. Any of these products may be applied to the scalp and hair, covered with a shower cap, and left on overnight.
How do you get head lice? Head lice usually spread from person to person by direct contact. But they may also spread by sharing items that touch your head (like combs, brushes and hats). Lice are most common in kids ages 3 to 12, as they're usually in frequent, close contact with each other.
Retreat according to over-the-counter treatment directions (usually 7-10 days). The treatment will not kill the nits, only the live lice, that is why you need to comb through hair every day.
Common symptoms of lice include:
Peppermint. Multiple studies show that peppermint is one of the most effective lice deterrents. Head lice hate the smell of mint, but fortunately, most humans love it! This is why we use peppermint in some of our products such as My Mint Spray.
Adult lice can only live a day or so without blood for feeding and nymphs can only live for a few hours without feeding. Nits will generally die within a week away from the host and cannot hatch at temperature lower than that close to the human scalp.
Getting head lice is not related to cleanliness of you or your environment. Although not as common, head lice may spread by: Wearing clothing, such as hats, scarves, coats, sports uniforms, or hair ribbons worn by an infested person. Using infested combs, brushes, or towels.
