Malathion I think that's what they sprayed for mosquitoes back in Arkansas. They do have alot of synthetics that work great on mites. Floramite and Avid work fantastic, but are kind of toxic if not used right. Here in Oregon,, if you have a trace of it in your herbs,, the state holds them back.
Spmetime around 1980, they malathion sprayed every square inch of California several times to combat the med fly invasion. Squadrons of helicopters flying over cities and fields.Sounds and images straight out of Apocalypse Now (and every other movie with an apocalypse in it.) They permanently destroyed most of the butterflies in the state, and several nice paint jobs on cars, but it seemed generally ineffective as an insecticide.
