Kerosene for Lice: Risks, Myths, and Safer Modern Alternatives

Searches for “kerosene for lice” still appear today, largely because it was a so-called “go-to” remedy for earlier generations. While kerosene was once used to suffocate lice, modern understanding makes one thing clear: the serious risks of fire, chemical burns, and systemic poisoning far outweigh any perceived benefit.

CRITICAL SAFETY WARNING: Kerosene is a highly flammable petroleum fuel. Applying it to the human body is dangerous and can result in chemical burns, permanent scarring, respiratory injury, or fire. Kerosene should never be used to treat lice.

The “Mechanical Kill” Misunderstanding

Kerosene did not work historically because of any special chemical action against lice. It worked only because of its viscosity. Like heavy oils, it blocked the lice’s spiracles (breathing openings), causing death by suffocation.

Today, as drugstore shampoos lose effectiveness against pesticide-resistant “super lice,” some people look back to kerosene out of frustration. What’s often missed is that modern, non-toxic physical suffocants now exist—and they achieve the same mechanical effect without the danger.

Kerosene vs. Safer 2026 Alternatives

Method How It Works Safety Profile
Kerosene Suffocation via fuel coating Extremely Dangerous
Dimethicone Physical silicone coating Excellent
Coconut + Neem Oil Asphyxiation + growth disruption Excellent

Better Alternatives That Actually Work

1. Dimethicone (The Modern Physical Standard)

Dimethicone is a non-toxic, silicone-based compound that works mechanically—not chemically. It coats lice and blocks their ability to regulate moisture, leading to death by suffocation. Because it is not a pesticide, lice cannot develop resistance to it.

2. The Salt & Apple Cider Vinegar Dehydration Method

A combination of warm apple cider vinegar and sea salt helps dissolve the glue that binds eggs to hair while dehydrating live lice. This addresses both adult lice and the egg stage—something kerosene never reliably achieved.

3. Precision Metal Nit Combing

In 2026, micro-grooved metal nit combs remain the most reliable tool for breaking the lice lifecycle. Daily combing for 7 consecutive days ensures that newly hatched nymphs are removed before they can mature and reproduce.

If Kerosene Has Already Been Applied

  • Wash the scalp immediately with warm water and a grease-cutting soap.
  • Move the person to fresh air.
  • Do not use a hair dryer or expose the area to heat or sparks.
  • Contact Poison Control if kerosene was swallowed or if skin irritation is severe.

Persistent lice is very hard to get rid of and some over-the-shelf products don't actually work. I remembered the elderly people talking about using kerosene for hair lice. I googled it and it said to use white kerosene (lamp oil). I filled up a spray bottle with white kerosene and sprayed my hair, being careful not to get any in my eyes. I left it on for 2 hours, then put on eye googles so none got into my eyes in the shower. I used shampoo to wash it off. Then I used a fine-tooth lice comb to remove lice. This worked more effectively than anything else. I started on Friday night and by Monday morning, I was free of lice. Thanks kerosene!

Growing up in India, whenever I had lice my mom applied kerosene and it worked well. Kerosene also helps any pain in the leg and knees. I always used to massag my grandma's legs with kerosene. It works.

We used kerosene to treat head lice when we were kids and never experienced any undesirable side effects. Sure, it smelled bad and the skin felt a little warm but you get used to it. It killed the lice AND EGGS with one treatment. We used cotton wool balls dosed in kerosene and wiped the hair, covering everything. Wrapped the hair in an old towel. We would stay like that for a few hours, then washed it off.

The hair grew strong, thick and shiny so I don't call that a bad deal. We were a large family and everyone got treated. It works. This is a remedy my great-grandmother passed on -- and say what you will about old wives tales, they often got things right!

My mum tried a modern treatment once, didn't kill the eggs and the lice returned with a vengeance. One other thing, rinse with diluted vinegar to help remove the eggs.

For those suffering from head lice, as well as many other tiny parasites that live in the hair and on the skin, do not be afraid of using kerosene! It is an old remedy that works and does not harm the skin or hair. It will even help cure at least some skin problems. The only problem is that it smells bad. It is a product of petroleum, just as is vasoline. Even diesel fuel is a good remedy since it is very closely related to kerosene; the only difference being the temperature used to distill the petroleum to produce the kerosene or diesel. In fact, my Dad told me that his father used to give him and his siblings a teaspoon of kerosene mixed with sugar for colds! Yes, taken internally! I tried two tablespoons once when having digestion problems and it took care of the problem! Having said all that, kerosene/diesel is not something to be taken for any and all illnesses. It is good for killing parasites, including on your pets. Try it.

Kerosene and other should never be taken internally. It's extremelly toxic just like gas or diesel. Do not try this remedy. It's also highly flammable, so I wouldn't use it on the skin either (it is also toxic that way through absorption).

There are lots of remedies for colds and other ailments on this site that are safe to be tried, but not this one.

I live in a 55+ community. An old WW2 vet (in his 90's) told me that when he was in Germany after the war, him and his friends would make homemade booze and that they added a touch of diesel fuel into the final product for TASTE!

That sounds like a very crazy and dangerous idea. I doubt the Germans added diesel to booze. That can literally kill you.

The Kerosene was indeed used medicinally in the past for various ailments....so was Turpentine, which I still use today. It works for cleansing the body, food poisoning, and the good ol' seasonal deworming routine. I also mix it it in with coconut oil and it's the goto for skin bites, bee stings, rashes, head lice, etc....the kids ask for it. The biggest problem is finding the pure products as you don't want to purchase from Home Depot. I get Georgia Pine on Amazon....read the reviews...as I'm not alone!

Just thought I'd tell you that my grandmother who was born in 1916 always told me about the time they got lice right after they had got married...and bought a used mattress after sleeping on the floor for months. They lived in rural Texas..and there was no running to a market in a wagon to get treatments...even had they the money during the depression. They certainly couldn't afford to throw away an infested mattress. They treated the mattress, bedding, AND themselves with kerosene (which they used for bedbugs in bedding when she was a child) and that took care of the problem, except for their eyelashes, which they picked off for awhile. I was always shocked when she told me about it...visualizing they soaked the mattress. She finally explained to me that they dipped a rag into kerosene and scrubbed the daylights out of it. As a result of her experience she always told me to drag out our mattresses and bedding into the sun to bake each side at least every spring, which I did faithfully till I couldn't drag a mattress outside anymore.

Don't use it unless you are desperate but it definitely works in one application. I had long hair and got lice on a trip to India. There were no shampoos for it where I was, local people were just shaving their heads to deal with it. I was determined not to return home with lice (and to keep my hair), so I got talked into washing my hair in kerosene. Be Careful to keep it off your skin, it got on my sunburn --- ouch!

I said not to use it unless you have to because it's bad for your hair.. I had to have my hairdresser put on all kinds of special conditioners to get my hair back to normal.
