Study was done at HARVARD about 10 years ago showing human head lice here in the US were no longer killed by our Pronto, Rid, etc. They'd developed immunity. Well, gee, I didn't need Harvard to tell me that (two kids through elementary school) I hear toothpaste does a pretty good job - is flouride a pesticide?
Toothpaste works? Not a problem for us anymore, but I'd sure like to pass the info on if it does????

Prolly works on the same basis as lime: no access to follicle on which to lay eggs, and no access to skin from which to suck blood. Minty fresh, too!
