"We are the first group to collect lice samples from a large number of populations across the U.S.," said Dr. Kyong Yoon, a researcher at Southern Illinois University at Edwardsville, in a press release. "What we found was that 104 out of the 109 lice populations we tested had high levels of gene mutations, which have been linked to resistance to pyrethroids."
Pyrethoids are a type of insecticide used for mosquitoes and other insects that contain permethrin, the active ingredient in over-the-counter lice treatment products.
Yoon collected lice from 30 states, analyzing them for knock-down resistance, or kdr, mutations. Kdr mutations cause changes that desensitize insects' nervous system to pyrethroid-based insecticides.
The vast bulk of states -- 25, including Florida, Texas and California -- had lice with all three of the genetic mutations associated with kdr. Of the other five Yoon gathered lice in, New York, New Jersey, New Mexico and Oregon had lice populations with one, two or all three of the mutations, and lice in Michigan were could still be killed with pyrethroids.

Here in NM we train plague fleas to kill mutant lice... had to do something once they outlawed cockfighting.

There’s always kerosene...
Kerosene and vegetable oil blend.

Awesome!
OK. I’ll say it.
They come here as an act of love.
Just reading this is making me itch.
Exactly.
Spot on. Old remedies are still the best. Eats straight through the buggers though it’s not the best smelling of stuff.
I never had to get treated with it, but I remember my uncle talking about my cousin getting that treatment. Curious if the vegetable was even needed though.
Sometimes I hate my hair but not enough to burn it down!!!
Besides, these are mostly coming from the invaders from the Third World Countries, who only want to share the love, Jebbie tells us about (along with whooping cough, measles, polio and drug resistant TB!)
Diesel fuel works......................
Boric acid, diatomaceous earth, and Vic’s vaporub.
The pesticides kill you before they’ll kill any insect.
My best result comes from cheap hairspray. Shellack the kid’s hair with it (like use the full can), leave it on for an hour or two and shampoo out. I figure it traps the adults and suffocates bugs and eggs at the same time. It has worked three times for me with girls whose hair was waist-length and thick. The hairspray is maybe a couple dollars a can, or less on sale. The cheaper and stickier the better.
