Make A Payment

Mice in your garage may seem like a minor nuisance, but the reality is far more concerning.

These small invaders can cause significant damage to your property, contaminate stored items, and even pose health risks to your family.

Keeping mice out of your garage is critical, especially in California, where mild winters and ample food sources make homes particularly vulnerable to infestations.

This guide will help you understand why mice are drawn to your garage, how to prevent mice from entering, and when to seek professional pest control services.

Why Do Mice Invade Garages?

Why Do Mice Invade Garages

Mice are opportunistic creatures that are constantly seeking food, shelter, and warmth. Garages are often ideal for them because they provide:

  • Easy Access: Small cracks, holes, or gaps in garage doors and walls are perfect entry points.
  • Storage Areas: Garages often contain boxes, tools, or holiday decorations that offer hidden nesting spots.
  • Food Sources: Pet food, birdseed, or garbage stored in garages can attract hungry rodents.
  • Warmth: California’s cooler months (even in mild regions) drive mice indoors for warmth and safety.

Understanding why mice are attracted to your garage is the first step toward keeping them out. Now let’s see how you can keep Mice out of your Garage.

10 Ways to Keep Mice Out of Your Garage

1. Seal Entry Points

Mice can squeeze through openings as small as a dime. Inspect your garage for gaps around doors, windows, vents, and the foundation. Use silicone caulk, steel wool, or expanding foam to block any openings.

  • Pro Tip: Pay special attention to where your garage door meets the ground. Consider installing a garage door sweep or weatherstripping to close the gap.

2. Declutter and Organize

Mice love clutter because it provides excellent hiding and nesting spots. Decluttering your garage makes it less inviting to rodents. Store items in sealed plastic bins instead of cardboard boxes, which mice can chew through.

  • Quick Tip: Create clear zones in your garage so that you can easily inspect for any signs of mouse activity.

3. Properly Store Food

If you keep pet food, birdseed, or pantry items in your garage, store them in airtight, chew-proof containers. Avoid leaving food out overnight, as even crumbs can attract mice.

4. Install Mouse-Proof Vents

Garages with vents are particularly vulnerable. Install vent covers made of fine mesh to keep mice from sneaking inside.

5. Keep the Garage Door Closed

Mice are quick and opportunistic. Leaving your garage door open, even for a short period, can invite them in. Make a habit of closing the door as soon as you’re done using it.

6. Use Natural Repellents

Certain smells repel mice, such as peppermint oil, cayenne pepper, and cloves. Soak cotton balls in peppermint oil and place them in corners or near potential entry points.

  • Bonus Tip: Replace the cotton balls regularly to maintain their effectiveness.

7. Install Traps

If you’ve already noticed signs of mice, set up traps in your garage. Snap traps, electric traps, or humane traps can help eliminate any existing rodents.

  • Safety Note: Place traps in areas where pets and children cannot access them.

8. Maintain Landscaping

Overgrown bushes, plants, or woodpiles near your garage can serve as hiding spots for mice. Trim vegetation and store firewood at least 20 feet away from your garage to reduce the risk.

9. Clean Regularly

Regularly sweeping and cleaning your garage removes crumbs, nesting materials, and other attractants. Focus on corners, underneath shelves, and areas behind stored items.

10. Use Ultrasonic Deterrents

Ultrasonic devices emit high-frequency sounds that repel rodents. These gadgets are easy to plug in and can be a helpful addition to other preventative measures.

Signs You May Have Mice in Your Garage

Signs You May Have Mice in Your Garage

To effectively keep mice out, it’s crucial to know when you already have an infestation. Look out for these common signs of mice in your garage:

  • Droppings: Small, black pellet-shaped droppings near food sources or in corners.
  • Chewed Items: Damaged boxes, wires, or furniture.
  • Nest Materials: Shredded paper, fabric, or insulation.
  • Noises: Scratching or scurrying sounds, especially at night.
  • Odor: A distinct, musky smell often accompanies a rodent infestation.

If you notice any of these signs, act quickly to prevent the problem from worsening.

Why DIY May Not Be Enough

While DIY prevention methods can be effective, a significant infestation often requires professional intervention. Mice reproduce rapidly, and a single overlooked nest can lead to dozens of mice in no time. A licensed pest control service will:

  • Conduct a thorough inspection of your garage and home.
  • Identify and seal all entry points.
  • Use professional-grade traps and treatments to eliminate infestations.
  • Provide long-term solutions to keep mice out.
