Step 3: Seal Entry Points
This is the single most effective strategy. Mice squeeze through holes the size of a dime, while rats fit through a gap the size of a quarter.
-
Inspect doors, windows, vents, and foundations.
-
Fill small cracks with steel wool and caulk.
-
Cover larger gaps with hardware cloth or sheet metal.
-
Install door sweeps and new weatherstripping.
Once rodents can’t enter, they can’t become a problem.
