What's Going On
Mosquitoes don't need a large opening — small frame gaps let them through. Airflow leaks often mean insect leaks.
What to Check First
- Look for visible light around window edges.
- Check if the existing screen is loose or sagging.
- Run your hand along the frame to feel airflow.
Quick Fixes
- Add or replace a magnetic mesh screen.
- Apply temporary foam strips to close small gaps.
- Use frame clips to secure sagging mesh.
