Bothered by These Suckers? Please Don’t Spray

I’ve read the statistics. I know bumblebee populations have declined by 90% and up to a third of firefly species may risk extinction.
That’s why I grow milkweed and pollinator plants and leave leaf litter for firefly larva. But am I making a difference? Do I see more monarchs? Mason bees? Moths?
The only insect I can vouch for is the mosquito. Populations appear to be flourishing, judging by yard signs, flyers and billboards promoting mosquito spray services.
From my side of the fence, the problem is this: If someone sprays a fine mist of pesticides at the shady, flower-free areas where mosquitoes rest, it won’t just kill mosquitoes.
“It can impact bees, butterflies, moths, caterpillars and insects that birds depend on as a food,” says David Mizejewski, a naturalist with the National Wildlife Federation.
The risks for pollinators can be obscured by the fact that backyard sprays commonly contain synthetic pyrethroids and insecticides that are related to natural pyrethrins found in chrysanthemum flowers. While chemically similar, synthetic pyrethroids are not eco-friendly or plant-based. They are broad-spectrum nerve toxins that the EPA says are “acutely toxic to bees and other insects.”
