How Do I Keep Mice Out Of My Garage?

People who live in houses built next to or close to fields or vegetation can understand how annoying it can be to find mice nesting in the corner of your garage. It is common for mice to barge onto your property, searching for food or shelter.

In Portland, temperature changes mean that your house may be pest-free during the summers. However, the winter is a mice-friendly season. They rush to garages for shelter from the cold breeze. This is the case for Old Garages that are not particularly used too often.

Which Things Attract Mice To Houses?

It has become somewhat of a tradition for rodents to lay grounds in inhabited houses. Their tiny and weak bodies find shelter in the houses we live in. By simply nesting in a house, mice are kept safe from snow, hail, rain, sleet, and even freezing conditions.

The cherry on top for mice is that we do not eat and end up being their food. For example, people who keep bird and grass seeds in their garages must have faced a mice problem at some point in life (if not multiple times).

Mice typically look for homes that do not have much activity. A rarely used garage is their favorite place. They lay nests there and breed. Once their pups are old enough, they move on to make their nests.

What Signs Indicate That I Have Mice In My Garage?

Mice have this habit of eating all the time whenever they are awake. One would find this surprising considering their size, but it is what they do.

  • Therefore, if you see droppings the size of rice grains and black or brown anywhere in your garage (or your home, for that matter), that is an obvious sign of a mice invasion.
  • Piles of droppings may be a common sight, but you can also see mice themselves. They tend to crawl along the walls and not in the middle of the room. Therefore, thoroughly scan the walls and corners if you suspect mice in your garage.
  • In addition, bird seeds, lawn seeds, or other edible items in your garage are consumed by mice. Therefore, you can find torn bags and scattered foodstuff in your garage in the presence of mice.

How Can I Prevent Mice From Entering My Garage?

The best way to avoid mice entering your garage is to make it as unappealing to them as possible. You can opt for the following measures to make your garage rodent-free:

  • Keep grass seeds, bird seeds, dog food, etc. in airtight containers
  • Keep things ordered and reduce clutter
  • Trashcans should be moved outside and sealed
  • Keep firewood outside away from your garage and house
  • Look out for any cuts or gaps that provide a passage into your garage.
  • Trim any extra tree branches that may be touching the roof of the garage

How Can I Prevent Mice From Entering My Garage?

Sealing off any passageways into your house is probably the most important thing in preventing mice from entering your home. Mice can squeeze through even the smallest of gaps. They can enter your home through holes as small as a dime!

Therefore, it is never wise to underestimate these clever little rodents. Even if you do not see mice in your house, it does not mean they’re not there. A single mouse can have about 25-60 offspring within a year.

How Can I Get Rid Of The Mice That Inhabit My House?

If you are looking to Eradicate a Mice Problem from your house on your own, there is a set of dos and don’ts you should keep in mind.


  1. Sealing gaps: Any small gaps and holes should be filled with caulk and steel wool.
  2. Cleaning the garage: Seeds and dog food were strewn here, and the perfect meal for mice was there. So, it would help if you prefer Cleaning Your Garage regularly.
  3. Organize your stuff: Prefer keeping items in containers and bins instead of carton boxes. Keep as much space open as possible. Lesser the occupied floor of the garage, the fewer hiding places.
  4. Trim back bushes and plants: If you keep the vegetation around your garage cut enough to prevent it from coming into contact with the house, there are fewer hiding spaces for mice.


  1. Creating high-pitched sounds: They have been proven to have no effect on mice treatment.
  2. Using essential oils and scents: The drive of eating the pile of birdseed in your garage can not be overcome by a small amount of peppermint oil.
  3. Relying on your cat: They might be able to catch mice, but they are no good as pest control.
  4. Using cayenne paper as a covering for garages: This “natural barrier” is useless against mice.
