Whenever I leave the window open with the screen, tiny gnats, or whatever they are called, go right thru the screen, and drive me nuts, Right now there are about 100 of them swarming around me. I have the smallest standard window screen I could find. This is the plastic type. I even put duct tape all the way around the screen frame to the window frame, so none of them can sneak in around any gaps. There are no holes in the screen. How can I stop this? I can not find any screen with smaller holes.
Thanks
Mark
