Moth Feathers
Just curious, where do you live? You must live in a really tropical area to have city-wide sprayings for mosquitos. xD I know only one other place that does it, New Orleans, and that's because they're a swamp.
If my research on mosquito chemicals is correct, the type of chemical they spray from planes is designed to kill adult mosquitoes is harmless to vertebrates and actually dissipates from the air/everywhere from hours to a couple of days, depending on what exact chemical is used. So I wouldn't freak out too much, perhaps just wash it with soap and water. Really there's not too much concern.
I live in south-central Florida. There are rivers and wetlands all around up (and we live on a river).

Any chemicals? Vinegar? Or just hot, hot water?
