How to keep mice out of garage?


Mice can be a nuisance when they invade your garage. Not only do they cause damage to stored items, but they can also pose health risks through their droppings and urine. If you’re wondering how to keep mice out of your garage, there are several effective methods you can employ. By following these steps, you can ensure a mouse-free environment and protect your belongings.

Seal Entry Points

Inspect and Seal Cracks and Holes: Mice can squeeze through even the tiniest openings, so it’s crucial to inspect your garage for any cracks or holes. Use caulk or expanding foam to seal these entry points, paying close attention to areas around windows, doors, and utility lines.

Install Weatherstripping: Weatherstripping is an effective way to seal gaps around garage doors. Ensure that the weatherstripping is in good condition and replace it if necessary. This will prevent mice from entering through the gaps.

Keep the Garage Clean

Remove Food Sources: Mice are attracted to food, so it’s important to remove any potential food sources from your garage. Store pet food, birdseed, and other edible items in airtight containers made of metal or thick plastic. Avoid leaving any food debris or crumbs on the floor.

Declutter and Organize: A cluttered garage provides mice with numerous hiding spots. Keep your garage organized by storing items in plastic bins or metal cabinets. This will make it harder for mice to find shelter and establish nests.

Eliminate Nesting Areas

Trim Vegetation: Trim any vegetation, such as bushes or tree branches, that come into contact with your garage. Mice can use these as pathways to access your garage. By keeping vegetation away from the building, you create a barrier that deters mice from entering.

Remove Clutter and Debris: Mice are attracted to clutter and debris as they provide ideal nesting materials. Regularly clean your garage, removing any unnecessary items, piles of paper, or cardboard boxes. This will eliminate potential nesting areas and discourage mice from settling in.

Use Deterrents

Ultrasonic Repellents: Ultrasonic devices emit high-frequency sounds that are unpleasant for mice. Place these devices strategically in your garage to deter mice from entering. However, keep in mind that these devices may not be effective in large open spaces or if there are obstacles that block the sound waves.

Mothballs and Peppermint Oil: Mice dislike the smell of mothballs and peppermint oil. Place mothballs or cotton balls soaked in peppermint oil in areas where mice are likely to enter. However, be cautious when using these methods, as they may be harmful to pets and children if ingested.


Keeping mice out of your garage requires a combination of sealing entry points, maintaining cleanliness, eliminating nesting areas, and using deterrents. By implementing these measures, you can significantly reduce the chances of mice infesting your garage and protect your belongings from damage.
