They do it in cities across Florida all the time to kill mosquito’s.
More so in areas that have a load of standing water.
It is also the reason most places here have no lightning bugs.
The stuff they spray with now only makes the skeeters mad.
They’d probably be better off spraying Prozac so no one cares if they are bit or not.
I keep usually a couple thousand breeding pairs of mosquitoes going in water features, puddles, etc. Rarely get bitten and of course I have a million predators like dragon flies. I can sit on my deck protected by dragon flies.
