Mice can multiply rapidly in your garage, with each litter ranging from five to twelve pups. It's essential to address the issue promptly to avoid property damage and health risks.

If you've noticed a mouse problem, it's time to eliminate them quickly and effectively. This prevents food contamination and the spread of diseases.

Whether they're nesting in the walls or hiding among the clutter, we've gathered practical strategies to deal with mice and prevent their return. If you've observed signs of mice in your garage, follow these six steps to keep your space free from these pests.

How to Eliminate Mice from Your Garage

You might unknowingly invite mice into your garage by creating an appealing environment filled with clutter and unsealed areas. Brett Bennett, a pest control expert, notes that garages often contain unsecured food and ample nesting materials in dark corners.

Start your pest control by addressing the reasons that attract mice to your garage.

1. Seal Food Sources

Mice are drawn to garages, especially when food is readily available. Ryan Farley, CEO of a pest control company, emphasizes the need to secure food sources like pet food and seeds.

Begin by sealing all food items in airtight containers, avoiding cardboard boxes that are easily chewed through. Regular cleaning can also help eliminate crumbs that attract mice.

Once food sources are removed, this may drive mice out, allowing you to seal entry points.

Water is another attraction for mice. Pest expert Georgios Likopoulos advises addressing any leaks and removing standing water to make your garage less inviting.

3. Declutter Your Space

Mice thrive where they can easily hide. Keeping your garage organized is crucial. Remove any items that might serve as hiding spots and ensure storage boxes are sealed and elevated.

Donnie Shelton, a pest control expert, suggests avoiding soft materials like newspapers or cardboard that mice can use for bedding. Consider garage shelving to keep floors clear.

4. Use Humane Traps

While making your garage unwelcoming is effective, using live traps can help catch mice. These traps allow for humane removal without harming the animals.

When using traps, place them in areas where you see signs of activity. The best baits include nuts, seeds, and sweets. After catching a mouse, release it far from your home to prevent return.

  • Position traps along walls where mice are most active, especially near gnaw marks or droppings.
  • Once a mouse is caught, release it at least a mile away to avoid its return.
  • Regularly clean and reset traps until you are certain no mice remain.

If relocating mice seems daunting, consider one-way doors that allow them to exit but not return. This strategy is effective if your garage is already unattractive to them.

5. Close Entry Points

After ensuring your garage is less appealing and using traps, inspect for entry points. Mice can fit through tiny gaps, so sealing these is essential.

Complete this step only when you're confident all mice are gone, to avoid trapping them inside. Use caulk for sealing and materials like steel wool around doors and pipes.

6. Use Deterrents

The final step in mouse-proofing your garage is to utilize deterrents that repel mice. They dislike scents like peppermint, cinnamon, and cloves.

Consider mopping the floors with cinnamon or soaking cotton balls in peppermint oil and placing them in potential nesting areas. Additionally, ultrasonic repellents can help drive mice away by emitting high-frequency sounds.


After removing mice, disinfect your garage to eliminate bacteria they may carry. Ongoing maintenance and organization are key to keeping your garage clean and clutter-free.

If the problem persists, consider reaching out to a pest control expert for tailored solutions and safe removal.
