Seal All Holes for Rodent Control
There is a simple but astonishing fact that mice can squeeze through a hole the size of a nickel, so you need to carefully inspect your home’s interior and exterior walls as well as the foundation for holes. Large holes or cracks should be repaired; small ones can be filled with steel wool or copper scouring pads. Secure the plug to the sides of the hole so the mice cannot pull it out. A more advanced solution is using metal mesh to secure all possible penetration points, thus keeping mice away.
