Step 1: Inspect Your Garage


The first step to keeping mice out of your garage is to inspect it thoroughly. Check the exterior of your garage for any holes or cracks that mice can use to gain entry. Look for gaps around windows, doors, and vents, and seal them with weatherstripping or caulking. If you have a garage door, make sure the seal is tight and there are no gaps at the bottom.


Inside your garage, check for any signs of mice, such as droppings or gnawed cardboard boxes. If you see any evidence of mice, it’s time to take action.


Step 2: Declutter Your Garage


Mice love to hide in clutter, so the next step is to declutter your garage. Go through your garage and get rid of anything you no longer need or use. Use plastic storage bins with tightly sealed lids to store items you want to keep. Avoid using cardboard boxes as they can easily be chewed through by mice.


Step 3: Seal Off Entry Points


Sealing off entry points is crucial to keeping mice out of your garage. Start by sealing any holes or cracks you found in step one. Use steel wool to fill small holes, and use caulk or expanding foam for larger gaps. If you have a garage door, consider installing a door sweep to seal off the gap at the bottom.


Step 4: Use Mouse Repellents


There are several mouse repellents you can use to keep mice out of your garage. Peppermint oil is a natural mouse repellent that you can use by soaking cotton balls in the oil and placing them around your garage. Another option is to use ultrasonic repellents that emit high-frequency sounds that mice can’t stand. You can also use commercial mouse repellent sprays or granules.


Step 5: Set Traps


Traps are an effective way to catch mice that have already made their way into your garage. There are several types of traps you can use, including snap traps, glue traps, and live traps. Snap traps are the most common and effective type of trap. They work by using a spring-loaded bar to snap shut on the mouse when it takes the bait. Glue traps work by trapping the mouse on a sticky surface, and live traps allow you to catch the mouse and release it outside.


Step 6: Keep Your Garage Clean


Keeping your garage clean is crucial to preventing mice from returning. Sweep your garage floor regularly and remove any debris or spills. Avoid leaving pet food or water bowls in your garage, and make sure your garbage cans have tight-fitting lids.


Step 7: Regularly Inspect Your Garage


Regularly inspecting your garage is essential to keeping mice out. Check for any new holes or cracks that mice may have created, and make sure your traps are still working. If you see any evidence of mice, take action immediately.




Keeping mice out of your garage requires a combination of preventive measures, mouse repellents, and traps. Inspect your garage thoroughly, declutter it, seal off entry points, and use mouse repellents. Set traps to catch any mice that have already made their way into your garage, and keep your garage clean. Regularly inspect your garage for any new signs of mice and take action immediately if you
