Man, back in the 70s, we used to follow the mosquito spray truck on our bikes while they were fogging our neighborhood. Riding through the fog waving to our parents while they were sitting on the porch laughing.
Problem is, the mosquitos that survived the years of pesticide onslaught, now have immunity and pass the immunity to the larva. The stuff you would have to spray now to kill them would most likely diminish the human population. lol
