How do mice get into houses?

Mice can be very resourceful when it comes to finding shelter from the cold or predators. Mice have many predators (foxes, cats, wild dogs, raptors, snakes and some insects) and they will do everything they can to ensure their survival. All it takes is a hole the size of a quarter for a mouse to sneak into a house.

They can enter through sufficiently large spaces around the house

The space between the door and the floor can be large enough to allow a mouse to pass through, especially if no weatherstripping is installed. Check that it is properly so. Not only will you prevent small unwanted animals from entering your home, but you will also save on heating costs.

Poorly sealed windows can also be a common entry point for small mice, in addition to leading to potential heat and energy losses. Make sure your windows are well sealed.

Cracks and holes in the foundation can be large enough to let a mouse in. It is therefore important to seal them well. For holes around pipes, it is best to first fill them with steel wool before caulking them.

Dryer ventilation ducts, attic vents and the intersection between the roof and soffits can be used for mouse entry. Indeed, they can take advantage of the space thus created to sneak into the attic. Covering these spaces with a thin wire mesh can help prevent this problem.

What attracts mice

Without necessarily entering a house, mice can take refuge around a building where they can find suitable spaces. Objects and debris in the yard or garage can make mice want to nest there. If you have a pile of firewood, consider raising it about 30 cm above the ground.

Food waste also attracts mice who will want to look for food there. Make sure that the trash can or compost bin closes tightly. If you make your own compost, install a wire mesh between the soil and the bottom of the bin.

Leaking faucets, open drains and oozing pipes can also attract mice, who will then use them for water. So be sure to eliminate these potential water sources as much as possible, especially by repairing leaking faucets.

Finally, once inside, the mice will look for food sources. That's why it's essential to keep your kitchen clean and store dry food in airtight containers that are made of glass, plastic or metal.

What if the mice are already inside?

If you suspect that mice are already inside your home or have nested at one of the entry points mentioned, avoid blocking them! This could cause more harm than good, especially if the mice remain trapped inside.
