How-to Keep Mice Out of Your Garage – 2019 Guide

Mice can be a real nuisance. They discreetly get into a space, and before you know it, you are faced with a full-scale infestation. There are many places that attract mice, but garages have to be an all-time favorite.

However, if mice are smart, we are smarter. There are several techniques that can keep those pesky mice out of your garage. 

In this article, you will find out exactly what these techniques are. So, get ready to rid your precious garage of mice. Let's get started! 

Why Do Mice Love to Live in the Garage?

Before we get into the "how", let's figure out the "why". In order to solve a problem, you must first ask yourself why it is happening. Once you can find out the root cause, solving the problem becomes much easier. In our case, the question is, why do mice love to live in garages? Let's find out why.


This is perhaps the main reason why mice love garages. Garages can double as a safe haven for mice and protect them from cold temperatures outside. While you might have a hard time visualizing your garage as a safe haven, for mice, it's the perfect place to settle in.


Yes! Another thing that mice like about your garage is the amount of shelter it provides. It keeps them safe from other predators. And let's admit it, garages are often cluttered. This clutter acts as a shield for mice, giving them more than enough places to hide. 

Ikea for Mice

Believe it or not, your garage is actually like Ikea for mice! They can find everything they need to build their cozy little homes on the premises of your garage. This includes cardboard, paper, and other such materials. 

How to Keep Mice Out of Your Garage

Now it's time to get down to business. In this section, we will list down a few steps you can take, which will help keep your garage free of those little critters. The things you need to do are not that difficult. The important part is that everything must be done thoroughly or else the uninvited guests will find a way back!

Clean Your Garage Thoroughly

This is the first thing that you need to do. Clean up the clutter and remove all unnecessary things. Be careful to remove everything and anything that could prove to be mouse-friendly. We do not need to give them any reason to stay. A clean space would mean that they have fewer spots for shelter and will probably find it hard to scavenge materials to build their homes. 

Another thing you want to clear out from your garage is food. This could include bird feed, dog food, etc. When you remove the food source, at least half of your problem will solve itself instantly. 

Close Any Access Holes

As mentioned before, mice are very pesky animals. They can fit into the smallest holes, ones you would think nothing of. However, for a mouse, that little hole is an entrance to a five-star hotel. So what you need to do is make sure to close all of these entrances. Some possible entrances could be access holes for vents or for plumbing. Air conditioner connections may also be vulnerable. Cracks in the flooring and the walls can also act as entryways for mice.

You want to make sure that all such holes are tightly sealed and do not have any gaps at all. You can use a vent guard for this purpose as they work really well. 

Fortify Your Garage Door

Alright, all possible entryways are sealed, but the mice still keep coming. Why? Well, they are probably just using the front door. Yes! It's as simple as that. If your garage door needs repairing or there is a gap between the door and the floor, that is an open invitation to the mice of the entire neighborhood. 

Make sure to check that your garage door closes completely and has no defects. Be sure to check the weather stripping as well because some troublesome mice may gnaw through it to make an entrance for themselves. 

Place Traps

Up until now, we have discussed how to keep the mice out. Now let's talk a little about how to deal with the mice that are already inside. These mice are particularly difficult to deal with because, by the time you notice, you are not alone. By then, these mice already know the ins and outs of the entire place. So the best plan of action for this situation is to set up mouse traps

Now, you could go for the newer electric traps that are fast and efficient, or you could use the traditional traps that snap. Either way, this is the easiest way to handle the situation. 

Use Mouse Deterrents

Mouse deterrents are a great way to deal with mice on the inside. They also help to keep the mice on the outside from getting inside. Ammonia is said to be a great mouse deterrent. A reason for that is it smells like the urine of another animal. This makes the mice wary, and as they are careful creatures, they instinctively avoid the place that smells like ammonia. 

Placing something that smells like another animal in the area could also do the trick. For example, if you have a pet, say a cat, then placing the cat litter in your garage will help, even more so if it is placed by the door.
