Have the bugs found the tear in your window or door screen? Thwart their entrance until you make a permanent fix by covering the hole with duct tape.
You notice a small hole has been poked in your window or door screen. If the hole is no more than about 1/4 inch (6 millimeters) in diameter, you can block the bugs and keep the hole from getting bigger by dabbing on a bit of clear nail polish.
Don’t invite the bugs in for a bite; use a small square of pantyhose to temporarily patch that hole in your window screen. You can secure the patch by simply applying some rubber cement around the hole before pressing the patch in place. When you’re ready to fix the hole with a piece of screening, peel off the nylon and the glue. If you want the patch to last a bit longer, sew it onto the screen with thread.
