Holes insects fit through
Best window screen repair
The best window screen repair is a patch or a new spline that actually closes the hole mosquitoes and flies are using. Mosquito control indoors at night is often a ripped corner, not a lack of yard spray. Buy a repair kit for small holes and a respline if the gasket has failed around the frame. Do not put fiberglass screen on a crawl vent and expect it to stop a rat.

Best repair kit: Window screen repair kit. Match the screen you have. A patch that does not bond, or spline that is the wrong diameter, leaves a whistle and a mosquito slot. Reseat the frame so the sash still closes.

Window screen repair kit
Best repair kit — Match the screen you have. A patch that does not bond, or spline that is the wrong diameter, leaves a whistle and a mosquito slot. Reseat the frame so the sash still closes.
Hardware
1/4-inch galvanized hardware cloth
Best for animal vents — If the “screen” is on a gable vent and you have had mice, stop buying fiberglass. Cloth belongs there. Window kits belong on windows.
Check the screen you do not look at
Bathroom windows, basement hoppers, and the screen door that bounces off the closer are the usual failures. A perfect bedroom screen does not help if the kitchen door stays ajar. Repair the hole, then look at door closers. For mosquitoes, also dump water. A new screen in a yard full of buckets is half a plan.
Common questions
What is the best screen material for mosquitoes?
Intact fiberglass or aluminum window screen in a frame that seats. The mesh count matters less than a hole you can see. Repair the tear.
Can I screen a soffit with a window kit?
Not if rodents are the pressure. Use quarter-inch hardware cloth fastened at the edges. Window screen is for insects.
Do screen repairs replace repellent?
They replace repellent indoors at a torn window. Outdoors you still want an EPA-registered repellent in mosquito and tick habitat.
