Animal Remover’s Tips to Keep Mice Out of Your Garage

Mice don’t need a lot of space to enter your home. An adolescent mouse can squeeze into a hole the size of a dime. It’s no wonder these creatures can get into very small spaces, get cozy, and live comfortably in your home without you ever knowing it. Today’s blog from Animal Remover explains how to keep mice out of your garage.

Why Do Mice Go in Garages?

Mice seek shelter to get out of the cold, find food sources, and hide from potential predators. They’re looking for the perfect combination of temperature, light, space, and humidity. Your garage may provide the parameters that mice prefer.

Secure or Remove Food Sources

Another factor you have to consider is the availability of food sources. People often feed their pets in the garage. That means there’s pet food or bird seed available for mice to eat. Those are attractive to the mice due to their incredible sense of smell. Animal Remover recommends keeping pet food sealed in sturdy containers or inside the house. Clean up any seed or food that falls on the floor. Put away leftover food after your pet is done eating. If you do store pet food in the garage, use metal or heavy-duty plastic containers to keep out vermin, pests, and animals.

Look for Entry Points

Before inspecting your garage for entry points, close your garage door. Then look at the weatherstripping where the garage door meets the concrete. Stand inside of the door and look down the entire length of it. If you see sunlight coming from underneath the door, you’ve got damaged weatherstripping. Mice can enter from that point. Even at just ⅜ inch high, a mouse can squeeze into the gap.

Now go to the outside of the garage door and look for gaps along the sides and top of the door. The most common spot for mice to enter is through the bottom at the corner, where vinyl weatherstripping meets the garage door. The vinyl weatherstripping may not be long enough to go all the way down to the concrete. It creates a gap, not only along the ground but also against the door where mice can squeeze into the garage.

Clean Every Season

Definitely clean your garage every so often, at least once a season. Cleaning the garage may seem like a “spring cleaning” thing, but really you need to take a look at least once every three months. Look under shelving, move all storage containers, and sweep out any dirt, dust, and debris. The reason is that mice will see the undisturbed debris and think it’s a safe place to hide because no one looks under there for a long time.

Animal Remover suggests you look for mouse droppings as you clean up. Also look for leaks in any pipes because that provides a regular water source for mice. Cleaning is 90 percent of the problem when it comes to mice. So long as the garage stays clean, you’ll mitigate most of your mice problems. 

Check Near Warm Places

Dryer vents, water heaters, and furnaces are all warm places that mice might live near. Look for any gaps around your dryer vent or dryer vent duct. Look for mouse droppings near your furnace and water heater as you clean up the utility room attached to your garage. Any electrical appliances may give off heat, even a standalone freezer. The Animal Remover team will look for mouse droppings near sources of warmth to find any signs of mice.

Solve the Entry Point Problem

Solving entry point problems depends on where the entry points are located. If you have a gap or unsealed dryer vent, you’ll have to use caulking to seal smaller gaps between the vent and the house. Or you could install a new dryer vent altogether.

For garage doors, you can install a new length of weatherstripping along the bottom if a gap exists there. Weatherstripping of this type is found at your local hardware store.

Vinyl weatherstripping along the sides of the garage doors requires a special kit, which Animal Remover techs can install for you. We use Excluder Professional Grade Garage Door Weatherstrip Shields. Each pack comes with two shields, and they are adhesive-backed metal barriers specifically designed to keep mice out of your garage. They’re metal, which means rodents can’t chew through them.
