I grew up in Florida. In the summer the mosquito fogger truck would come down the street every night while we were still out playing kickball or something. We used to just stand there and get enveloped in the fog. Some nights the mosquito dusting plane would fly over dropping dust. We used to run up under the overhang of the porch til it passed over and then resume playing. As far as I know most of usdusd are still around to talk about it. :-)
The fogger trucks still run periodically in the evenings, at least here in Jax. Since there are no notices or warnings I assume it won’t kill us. I see no evidence it harms anything but the mosquitos. No shortage of other bugs or frogs etc.
