I know this is a dumb question and I'm pretty confident the answer is a big NO! You northern guys may not know what these are or maybe its just a southern bug. Has anyone every treated homes for knats? They are so bad out here you can't even enjoy a beer on the deck with the grill fired up!! I've been told that mosquito treatments are pointless unless you get a good block of neighbors treating as well. I figure knats might be the same way.
