How to keep wasps away
Seal cracks in your home.
This can prevent wasps that have nests near your home from actually getting in. Look for cracks near the edges of your siding, where power lines enter your house, or holes in window screens.
Then use an appropriate sealant-usually caulk for cracks near the siding or where power lines enter and patches for screens-to seal the holes. If you find a wasps nest in one of the cracks or holes you're sealing, don't just seal it in.
