The problem wasn't them spraying the mosquito killer, it was doing it during the day. They had sprayed many times before and since without any problems but they always spray at night.Sorry, the angry wasn't for you. What makes me angry is the county assuming that spraying a pesticide is a good idea.
Don't be surprised if they are spraying for mosquitoes where you live too. If they stopped doing it, there would be an uproar over the mosquito explosion.
