In my neighborhood we have these truck that come around from time to time and spray a mist as they drive by. I assume it is some sort of pesticide to control mosquitoes or something. Anyway it came by at about 9pm and a few moments after I opened my door without thinking, it was open for just a few seconds before I shut it. At 11pm about two hours after the truck came by I took the trash cans out to for pick up in the morning. Could I have breathed some of the stuff in this way? Would two hours have been enough for it to dissipate?
