Mouse Holes

Mouse holes come in many shapes and sizes. Mice can get through holes just over 1/4″ in diameter. I call any opening or space a mouse hole, simply because mice can come into or move around in your home because of the hole (or holes).

Entry Holes

These are holes that mice can use to get into the house in the first place. Mice do not normally make these holes, they just use them to access your home. The first thing to do if you find you have a mouse problem is to locate every single entry hole, and plug it up.

Entry holes can be cracks or spaces in the siding or floor boards, holes where pipes or utilities come through, attic vents with torn screens, or even just open windows or doors. In order to find mouse holes, You may have to crawl under the house or through the attic, move appliances and furniture, or crawl under the sink. Follow the path the mouse or mice made, and fill every hole thoroughly.

Pathway Holes

These are holes that the mice use to move around once inside your home. These holes can be existing, or mouse-made.

Pipes that lead between the walls are often hidden (such as pipes under a sink), and any space between the pipe and the wall is easy access for mice. Mice will often chew holes through baseboards, cabinets, any where it needs to make a path to move stealthily through the house.

Before you fill in the pathway holes, you will want to trap the mice and remove them. This process could take a while, but if you simply fill in these holes the mice will likely die inside your walls, because their entry holes are filled and they cannot get out of the house for food or water.
