I remember, when I was a little kid back in the middle to late 1960's, running through the clouds of mosquito pesticide when the spray truck would go through my neighborhood. Back then, the clouds of pesticide the trucks produced were much larger and more opaque then they are now.
Myself, and kids throughout the neighborhood, would follow the truck around and run in and out of the cloud of mist the truck produced.
Once in a while I've wondered if that exposure to pesticide ever caused me any kind of problems.
I worked 4 years of mosquito abatement in the western suburbs in the '80's. I had to be licensed by the state to mix and handle malathion. It was stupid easy to get a license, but still. I handled it a lot and I ain't dead. Breathing in chemical vapor (especially as a child) is never a good idea though, and we had to shut down or leave our route if we got followed by the neighborhood kids.
Adult mosquitos are the hardest to kill, so that night spraying crap is only marginally effective. It serves as much as a placebo effect. We had a lab crew that maintained about 30 traps all over our region. Every day they'd swap them out, sort the insects by gender and species, and count them. That and weather determined whether we'd go out at night. Most of our work was during the day spraying for larva. That stage of the insect is easiest to kill. We mostly used a type of biodegradable oil that formed a thin layer on the surface of the water. Mosquito larva breath air through their ass (not really, but close...). They can't breath through the oil so they die. Other thing we used was BT. That was more for some big propeller driven spray rigs we had on 1 ton trucks that we used in the Forest Preserves. We also had several aquariums where we bred a type of fish that lives exclusively on mosquito larva. Those went to golf courses and cemetaries and places that had ornamental ponds.
Old tires. Fuckin' mosquito LOVES to breed in old tires. Bad mosquitos too...the kind that transmit encephalitis. I spent a lot of time spraying big collections of old tires.
yer mosquito is a great food source for a number of critturs. Annoying it may be, but it fills it's hole in the ecosystem
