Why Peppermint Oil Repels Mice

Sense of Smell

Mice have a very strong sense of smell, which they rely on greatly due to their weak vision. As a result, they are extremely sensitive to scents in their surroundings, and certain smells can be incredibly overpowering for them.

Peppermint oil is one of these scents! Its strong smell is actually quite unpleasant for mice, making it an effective and natural way to repel them from your garage.


Peppermint oil contains a powerful ingredient called menthol, which research done at Cornell University suggests can overwhelm a mouse’s sense of smell. When you use peppermint oil in your garage, the menthol dominates their olfactory receptors, making it difficult for them to detect any other scents, like food, that might otherwise attract them.

Here’s a breakdown of peppermint oil’s repelling power:

5 Ways to Use Peppermint Oil for Mice Control

If you’re trying to use natural methods to repel mice, peppermint essential oil can be pretty handy! Especially in your garage. Let me share my experience with using this amazing oil to keep mice away.

Methods of Application

  1. Spray bottle: Simply mix two teaspoons of 100% peppermint oil (like this awesome 100% Pure and Natural Peppermint Oil from Brooklyn Botany) with one cup of water in a spray bottle. Spray around your garage and where you notice mice activity. The scent will deter them without harming them or affecting the environment!

  2. Cotton balls: Soak cotton balls in peppermint essential oil and place them strategically around your garage. Mice hate the scent and will avoid the area.

  4. Essential oil diffuser: Place an essential oil diffuser in your garage and add a few drops of peppermint oil. The scent will spread throughout the space, and it might make your garage smell nice too!

Success Rate

Peppermint oil can be an effective, natural repellant for mice due to their highly sensitive noses and acute sense of smell. When used correctly in your garage, it might keep mice away from specific spots. However, it may not guarantee complete eradication of these furry critters, so it is essential to be vigilant!


Let me share some considerations about using peppermint oil in your garage. Firstly, use a 100% Pure Peppermint Oil for maximum effectiveness.

Remember, the scent of peppermint oil also helps mask other smells that might attract mice, like food odors, so placement is essential! Think garbage cans, near refrigerators, and make sure to spray it wherever there is an opening or gap!


While peppermint oil can provide some relief from a mice problem, it is not foolproof. Here are a few limitations to keep in mind:

  • Peppermint oil might keep mice away from certain areas, but it may not completely eliminate them from your garage.
  • The scent may become less potent over time, so you need to replace the cotton balls or spritz more often.
  • This method could work less effectively when dealing with larger infestations.
  • Be cautious when using peppermint oil around pets, as its strong scent might overwhelm them.

Alternative Ways Of Using The Peppermint Scent To Repel Mice

There are other ways to use peppermint, without using peppermint oil only! Check out these ways below!

  1. Wintergreen Oil: Wintergreen oil has a strong scent that mice find unpleasant, making it an effective deterrent. To use wintergreen oil, soak cotton balls in the oil and place them in areas where mice are present, such as near baseboards or in cabinets. You may need to replace the cotton balls every few days as the scent wears off.
  2. Spearmint Oil: Like wintergreen oil, spearmint oil also has a strong scent that mice find unpleasant. To use spearmint oil, soak cotton balls in the oil and place them in areas where mice are present. You may need to replace the cotton balls every few days as the scent wears off.
  3. Altoids and Mint Candy: Altoids and other mint candies contain natural mint oils that mice find unpleasant. To use Altoids or other mint candies as a deterrent, crush them and sprinkle them in areas where mice are present, such as near baseboards or in cabinets. You may need to replace the crushed candy every few days as the scent wears off.
  4. Mint Mouthwash: Mint mouthwash can also be used as a mouse deterrent. Mix equal parts of peppermint mouthwash and water in a spray bottle and spray in areas where mice are present, such as near baseboards or in cabinets. You may need to reapply the spray every few days as the scent wears off.

It’s important to keep in mind that while these methods may help deter mice, they may not be effective for severe infestations. If you have a serious mouse problem, it’s always best to consult a professional pest control service.

Other Essential Oils That Will Keep Mice Away

Lavender oil is another fantastic option to deter mice! Just like peppermint oil, it has a strong scent that mice find unbearable. You can create a similar solution, mixing one part lavender oil with five parts water, and spray it around your garage. Tale as old as “thyme”?

Speaking of which, thyme oil can also help in repelling those pesky rodents. The strong scent of this essential oil overwhelms their sensitive olfactory systems, keeping them at bay. While using thyme oil, remember to dilute it just like the other oils mentioned. A little “thyme” and patience spent today will keep the mice away!

Another great option is lemongrass oil which possesses a fresh and citrusy aroma. This scent is something you might enjoy, but for mice, it’s a different story. By spraying a diluted solution of lemongrass oil around your garage, you will be telling those mice to “lemongrass” out of your home.

Pine and balsam fir oils are also effective. Mice dislike the scent of these crisp and refreshing oils. Mix a few drops of either pine or balsam fir oil with water and spray it on the areas you think mice might enter.

Looking for something more exotic? Well, bergamot oil might just be the answer! Featuring a unique citrus aroma, bergamot oil can be an effective mice deterrent. Give it a try by creating a solution of bergamot oil with water and spraying it around your garage.

Who doesn’t love the smell of eucalyptus oil? Well, mice, that’s who. This strong, refreshing scent is simply unbearable to their sensitive noses. Mixing a eucalyptus oil solution is a breeze, and once you’ve sprayed it around your garage, those little critters will be saying “eucalyp-NO thank you!”

Finally, lemon oil is another effective essential oil to repel mice. Its fresh and zesty aroma, while pleasant to you, is a big “nope” for mice. Create a lemon oil solution and spray it around your garage to help keep those furry intruders away.

Alternative Natural Repellents

Herbs and Spices

Cayenne pepper, cloves, cinnamon, and rosemary can also be used as natural repellents to deter mice from your garage. These spices are a powerful aroma-posse that mice aren’t fond of. Place these spices in small jars with holes in the lids or sprinkle them around entry points, cupboards, and nesting areas, giving mice a clear message – this garage is off-limits!


One more ingredient from your kitchen that could double up as a mouse deterrent is vinegar. Its strong smell is a turn-off for mice, who’d rather stay away from such pungent places! To use vinegar as a repellent in your garage:

  1. Mix equal parts of water and vinegar in a spray bottle.
  2. Spray the solution along walls, entry points, and other mouse-targeted spots in your garage.

You’ll not only keep mice at bay but also keep your garage spick and span, thanks to vinegar’s cleaning properties!

Dryer Sheets

Dryer sheets are another effective, yet unconventional method to repel mice. These sheets release a scent that is pleasant to us but irritating to our little unwanted visitors. Here’s a trick: to cover a larger area, tear the sheets into smaller pieces and place them in different spots around the garage. Make sure to replace the sheets once the fragrance fades away.

Tea Bags

Not just for sipping anymore! Used tea bags can serve as a natural deterrent against mice. Brew a strong cup of mint tea, and simply place the used tea bags in your garage. Mice aren’t fans of minty scents, and their presence will steep-away the invaders. You can also try other fragrant tea varieties like rosemary or lavender, as these scents are disliked by mice too.

And hey – they even make peppermint tea bags like these 100 Pack of Organic Peppermint Tea Bags – definitely worth a shot!

Aluminum Foil and Steel Wool Keep Mice Away

If you’re finding yourself in constant battles with mice in your garage. Peppermint oil can be a great natural solution to keep these pesky critters away.

But wait, before we dive deep into the world of peppermint oil, did you know that aluminum foil and steel wool can also play a role in keeping mice at bay? A great combination, isn’t it?

To double up on your mouse-prevention efforts, combine peppermint oil with good old aluminum foil and steel wool. Here’s why they’re helpful:

  • Mice have trouble gnawing through these materials, making it difficult for them to enter your garage.
  • Filling gaps and crevices with aluminum foil or steel wool blocks their entry points, further keeping them away.
  • The shiny, crinkly sound of aluminum foil can also be a deterrent for the sensitive ears of mice.

Plants Can Also Keep Mice Away

Along with the peppermint oil you might have just started using in your garage, let me tell you about a more natural alternative! Did you know that you can also use peppermint plants and other plants to repel mice? Yes, you heard it right! But what else keeps mice away? Well, let’s find out with some natural and scientifically backed options!

  • Peppermint plants not only release a fresh scent across your garage but deter mice from entering. They don’t really like the minty-fresh smell!

  • Planting citronella around your garage will provide another layer of mice-repellent scent. Just think of it as taking a more aromatic approach to pest control!

Fun fact: I once planted citronella in strategic spots, and my garage has been rodent-free ever since. So, believe me when I say it works!

  • Lavender is not only a magnificent, fragrant plant, but it too can keep mice at bay. The plant’s essential oil, present in the leaves, creates an odor barrier that mice simply dislike!

So why do these plants work, scientifically? It’s all about their essential oils! These natural oils contain compounds that evoke a strong sense of smell. For mice, whose sense of smell is much stronger than ours, these plants release overpowering aromas, deterring them from hanging around. It’s nature’s way of saying, “Not so fast, little intruders!

Remember, keeping mice away is all about maintaining an environment they won’t want to be in. So, be it peppermint oil, citronella, lavender, or other aromatic plants, you can trust in the power of their scents to keep your garage rodent-free. Set the right mood for your garage, and those mice will scurry away faster than you can say, “mouse-be-gone!


It’s clear that peppermint oil can be an ally in your battle against mice in your garage. Not only is it a natural and eco-friendly option, but it also boasts a pleasant scent.

You might wonder, why is peppermint oil so effective against mice? It’s because they have a highly sensitive sense of smell and find the strong aroma overwhelming. This makes it a great deterrent for them when placed around your garage.

Now, you must be curious how to use peppermint oil in your garage. Here’s an easy method:

  • Soak cotton balls in 100% peppermint oil
  • Strategically place them around the garage, focusing on areas prone to mouse activity

Another option is creating a spray by combining two teaspoons of peppermint oil with one cup of water. Spray it around the garage, paying special attention to potential entry points.

But, keep in mind that relying solely on peppermint oil might not completely eradicate your mouse problem. It’s still essential to take other preventive measures, such as:

  1. Sealing potential entry points
  2. Keeping your garage clean and clutter-free
  3. Storing food in airtight containers

By incorporating peppermint oil along with these measures, you can better protect your garage and keep those pesky rodents at bay. Honestly, who doesn’t want a mouse-free garage?!

So give it a try! Keep those unwanted guests away using peppermint oil, and enjoy the peace of mind in knowing you’re using a natural, eco-friendly solution tailored to your needs. Happy mouse repelling!
