The Bottom Line
Keeping mice out isn’t necessarily about finding one magical repellent or household trick.
It’s about making your home harder to enter and less rewarding once they get inside.
Seal possible entry points, protect food, reduce clutter, keep garbage contained, and investigate signs of activity early.
And if the problem continues, don’t hesitate to seek professional help. A proper inspection can often reveal problems that aren’t obvious from inside the living areas of your home.
The best mouse-control strategy is prevention: block the door, remove the buffet, and eliminate the hiding places.
