If you have a mouse problem in your garage, it’s time to take action! While mice CAN cause damage to your property, did you know that there are natural ways to deter mice from making your garage their home?
Understanding mice behavior is essential when trying to repel them. Mice have a strong sense of smell and are repelled by certain scents as their survival instinct to avoid potential dangers kicks in.
In this article, we will focus on the 15 best scents that can help you keep your garage mouse-free, in an eco-friendly and humane way – let’s get to it!
- Use scents that are known to repel mice naturally, such as peppermint oil, clove oil, or black pepper to keep your garage mouse-free
- Identify potential entry points and address the issue to prevent future infestations
- Combine scent-based deterrents with other natural methods for a comprehensive garage mouse control strategy
Why Scents Help Deter Mice From Your Garage
How A Mouse’s Sense of Smell Works
Mice have an incredibly strong sense of smell, which they rely on to detect food and avoid predators. This makes their olfactory system a potential weak spot, where natural scents can be employed against them to help keep your garage mouse-free!
Interestingly enough, mice can ‘learn’ to avoid certain smells if they are exposed to them. Chapter two of the book Behavioral Genetics Of The Mouse found that mice exposed to certain smells over time learned to avoid them, especially if no reward (such as food) was given after smelling the odor.
With that in mind, it’s super important not only to use repellent scents, but also to avoid giving mice a free buffet in your garage!
15 Scents To Keep Mice Out Of Your Garage
When thinking about the best scents to keep mice away, consider their natural aversions to certain smells. For instance, ammonia is a smell that mice despise because it resembles the urine of predators.
On the other hand, something like cayenne pepper will irritate their senses, making them less likely to stick around that area.
Now, let’s check out 15 natural scents that will help keep out tiny rodent intruders.
Peppermint is a natural scent that mice hate. You can use peppermint oil or fresh peppermint leaves to keep mice away from their garage. Simply place a few drops of peppermint oil like MAJESTIC PURE Peppermint Essential Oil on cotton balls and place them in areas where mice are likely to enter, or plant peppermint around the perimeter of your garage.
Eucalyptus oil has a strong scent that mice find unpleasant, making it a great natural repellent. Use eucalyptus oil to repel mice by placing a few drops on cotton balls and placing them in areas where mice are likely to enter, or by using a diffuser to spread the scent throughout the garage.
Lavender is a natural scent that mice find repulsive. To use lavender to repel mice, try lavender oil or dried lavender. Place a few drops of lavender oil on cotton balls and place them in areas where mice are likely to enter or hang dried lavender around the perimeter of your garage.
Alternatively, use lavender sachets like Lavande Sur Terre French Lavender Sachets. Place these strategically around the garage to repel mice.
4. Cloves & Clove Oil
Clove oil has a strong, spicy scent that mice don’t like, making it a great natural repellent. Like other essential oils, use clove oil to repel mice by placing a few drops on cotton balls and placing them in areas where mice are likely to enter, or by mixing clove oil with water and spraying it around the garage.
Citronella oil is commonly used to repel mosquitoes, but it can also keep mice away from your garage. Place a few drops on cotton balls and place them in areas where mice are likely to enter or use a citronella candle in the garage to disperse the scent. TIKI Brand 28 Ounce Citronella Wax Candle works great at releasing the citrusy scent of citronella.
6. Cayenne Pepper
Mice don’t like the spicy scent of cayenne pepper, so sprinkle it around your garage to keep them away. Alternatively, try making a homemade spray by boiling cayenne powder with water and placing it in a spray bottle once it cools. Spray this around the outdoor perimeter of your garage.
7. Balsam Fir
Balsam fir oil has a fresh, woodsy scent that mice find unpleasant, making it a great natural repellent. Use this scent in a similar way to our other essential oils, by either soaking cotton balls or making a DIY spray.
Rosemary has a strong scent that mice don’t like. Use fresh or dried rosemary to repel them. Simply place a few sprigs of rosemary around the perimeter of your garage or in areas where mice are likely to enter.
Mice hate the strong scent of mint because it overwhelms their sense of smell, making it difficult to locate food or sense predators. Place a few drops of mint oil on cotton balls and place them in areas where mice are likely to enter, or plant mint around the perimeter of your garage.
Vinegar has a strong, pungent scent that mice find unpleasant, making it an ideal mouse-repellent. Use vinegar to repel mice by mixing equal parts vinegar and water in a spray bottle and spraying it around the garage.
The sweet smell of cinnamon may be pleasant to us, but mice find it too overpowering. Use cinnamon sticks or powder for this method. Simply place cinnamon sticks around the perimeter of your garage or in areas where mice are likely to enter, or sprinkle cinnamon powder around the garage. Try McCormick Cinnamon Sticks for this method!
Catnip is part of the mint family and has a similar affect on mice. Growing catnip around the perimeter of the garage is one option. Or, use catnip essential oil and dab it on some cotton balls.
Garlic is a versatile culinary ingredient, and also an excellent way to repel mice naturally! The strong, pungent scent overwhelms a mouse’s olfactory system, making it difficult for them to find food, mates, or to sense predators.
To use garlic to repel mice from the garage, make a DIY spray. Place a few cloves of crushed garlic in a pot of boiling water. Reduce and let simmer for 10 minutes. Let the mixture cool and strain it into a spray bottle.
Crushing the garlic is key – this releases the strong scent we’re so familiar with. Just planting garlic or placing cloves around the garage won’t cut it.
Onion and garlic go hand-in-hand. They both produce a strong scent when crushed. This is actually a defense mechanism to avoid being eaten by herbivores! Lucky for us, onions also repel mice.
You can create a DIY spray similar to garlic by boiling water, adding onion slices, and letting it simmer for about 10-20 minutes. Allow the mixture to cool, strain it, and add it to a spray bottle.
Pro tip: Combine sliced onion and crushed garlic into the same mixture for an extra powerful scent deterrent!
15. Bay Leaves
Bay leaves have a strong, spicy scent that mice don’t like. Try placing bay leaves in a sachet filled with rocks (to weigh it down) and placing the sachets around the outside of the garage or in the interior in dark cozy corners where mice are likely to lurk.
Most Common Signs Of A Mice In Your Garage
Detecting a mice infestation early on is vital in order to prevent them from spreading and causing damage in your garage. Look for these key signs:
- Droppings: Mouse droppings are small, dark, and often found clustered in specific areas.
- Rustling sounds: Mice are nocturnal creatures, so you may hear rustling or scratching noises at night.
- Squeaking: Listen for high-pitched squeaks that indicate mice communicating with each other.
- Gnaw marks: These can be found on wood, cables, or other materials that mice like to chew on.
- Nests: Small, shredded materials in hidden and cozy places are signs of nesting.
Keeping your garage tidy and well-maintained plays a key role in preventing rodent issues. When searching for ways to keep mice out, it’s crucial to learn about their behavior patterns and preferences.
Identifying Mouse Entry Points Around Your Garage
When it comes to preventing mice from infiltrating your garage, the first crucial step is identifying entry points. Mice are notorious for squeezing through the tiniest of holes and gaps to access warm shelters like your garage. By taking preventive measures, you can have the upper hand against these pesky rodents!
Inspect The Garage
For starters, inspect your garage thoroughly. Be on the lookout for potential entryways, such as holes in the walls, gaps around doors, or even openings near utility pipes. Remember, mice are capable of squeezing through openings as small as a quarter of an inch.
If it’s hard to find these entry points, try looking during nighttime when garage lights are switched on – this will make any openings more evident as light escapes from the inside.
Once you have located all possible entry points, it’s time for some exclusion strategies. Sealing these gaps and holes is an effective way to prevent mice from gaining access to your garage.
Here are some tools and materials to use to seal gaps and holes in the garage:
- Hardware cloth – this is great for larger gaps and holes in the garage. Be sure to get 1/4-inch or smaller. Otherwise, mice will be able to squeeze through it!
- Weather stripping – add weather stripping to garage doors to remove small openings at the bottom that mice may be sneaking through.
- Steel wool – an excellent tool for smaller gaps and holes.
- Copper mesh – another great option for small gaps and cracks.
- Expanding foam – use this on cracks to seal the up tight.
- Caulk – Use caulk to seal in steel wool and copper mesh. Use it to seal any gaps around windows as well.
Why Mice Are Attracted To Garages
So why do mice come to your garage in the first place? Primarily, they seek food, shelter, and breeding grounds.
Here are some common reasons why mice are attracted to the garage:
|Food sources||Mice are attracted to garages that have food sources such as pet food, birdseed, or garbage. These items provide a reliable food source for mice.|
|Shelter||Mice are attracted to garages that provide shelter from the elements. Garages that are cluttered or have openings provide a safe haven for mice to nest.|
|Water sources||Mice require water to survive, and garages that have standing water, leaky pipes, or condensation provide a reliable water source for mice.|
|Warmth||Mice are attracted to warm areas, and garages that are heated or have warm equipment provide an ideal environment for mice to thrive.|
|Clutter||Garages that are cluttered provide ample hiding places for mice to nest and avoid predators.|
|Openings||Garages that have openings such as gaps in doors, windows, or walls provide easy access for mice to enter and exit.|
|Neglect||Garages that are neglected or infrequently used are more likely to have mice since they are less likely to be cleaned or maintained.|
|Nesting materials||Garages that have materials such as cardboard, paper, or fabrics provide nesting materials for mice to build their nests.|
|Scent||Mice have a strong sense of smell and are attracted to the scent of other mice or their droppings. Garages that have had mice in the past may attract new mice due to the scent.|
|Climate||Certain climates are more conducive to mice, and garages in these areas may be more likely to have mice. For example, garages in humid or wet climates may have more mice due to the abundance of water.|
Why Mice In Your Garage Is A Problem
Mice are notorious for damaging property in a multitude of ways. They love to chew on stuff, and this means they’ll gnaw on your insulation and wiring. Damage to wires can lead to electrical malfunctions or even dangerous fires!
Additionally, these tiny critters are capable of causing structural damage to your home by chewing through walls or doors, creating holes and potential entry points for other pests.
Additional Natural Mouse Repellent Solutions For Your Garage
Having a cat or dog in the home can help deter mice, as these pets are natural predators of rodents. Just the scent of a cat, for example, can keep mice away by making them believe a predator is nearby. Your furry friend may even catch a few uninvited guests for you!
Sealing Entry Points
Keeping mice out starts with proper sealing of entry points in your garage. Mice are excellent climbers and can slip through the smallest of spaces.
To ensure their unwelcome visits come to an end, make sure to seal all gaps, cracks, and holes in your garage. This will not only provide a barrier for rodents but also help keep other unwanted invaders like insects out.
Maintaining Cleanliness and Order
Mice are attracted to clutter, debris, and easily accessible food sources. By keeping your garage clean and removing potential nesting areas, you can discourage mice from making it their home.
Some tips to maintain cleanliness and order include:
- Store food items in airtight containers
- Keep trash cans sealed and take out the trash regularly
- Remove any piles of debris, like leaves or wood
Remember, a clean garage is not only visually appealing but also less attractive to rodents.
Use of Traps
While avoiding poison bait is essential for keeping pets and other non-target animals safe, you can opt for other types of traps such as snap traps or live traps. These methods are more humane, effective, and safe. Be sure to follow the trap instructions carefully and check them regularly.
Light and Sound
Mice tend to avoid bright lights and sudden, loud noises as these conditions make them feel exposed and vulnerable. Consider installing motion-activated lights in your garage or setting up a noise-emitting device that can scare them away. This non-invasive approach can help discourage these little mammals from getting too comfortable in your space.
Deterring mice from your garage can be achieved by addressing their basic needs: shelter, food, and safety. By implementing these natural mouse-repellent methods, you’ll be well on your way to keeping your garage mouse-free, in harmony with both nature and your pets.
Professional Pest Control
While not necessarily a ‘natural’ remedy to keeping mice away, a professional pest control service can help when other methods don’t seem to be working. Pest pros can identify how mice are getting into the garage and seal off entry points to prevent future infestations.
Consider using our nationwide pest control finder to connect with a local pest professional that aligns with your preferred repellent methods!
