How to Keep Mice Out in Winter
Why fall prep matters more than winter reaction.
Seal Before It Gets Cold
Mice can fit through gaps as small as a dime — checking the foundation, utility entry points, and door sweeps before winter is more effective than treating after they’re inside.
Remove Outdoor Shelter Near the House
Woodpiles and dense vegetation right against the foundation give mice a staging area before they find a way in.
If They’re Already In
Trapping addresses the current population, but without sealing entry points, new mice tend to replace the ones removed.
