If you’re tired of unwanted mice invading your home, your spice cabinet (or veggie drawer) may have just the answer for you!

Mice, like humans, have a strong sense of smell and taste, which is why spicy and pungent substances can be effective at keeping them away. While the actual strength of the scent can highly vary – strong aromas can be effective at masking scents that would otherwise attract mice, causing them to naturally stay away!

The capsaicin found in hot peppers (and piperine in black peppers) is known to be irritating to rodents (as an added bonus), so incorporating pepper repellent into your pest management strategy can be both an eco-friendly and effective solution! Alongside pepper, there are also other potent ingredients that can be used to create alternative repellents for a comprehensive approach to a mouse-free home, naturally 🙂

Now that you have an idea of how pepper can help you in your battle against mice, let’s dive into the specifics of making your own, using it correctly, and exploring other spicy options for mouse control.

All it takes is a little creativity and some spicy knowledge to make your home a mouse-free zone!

Key Takeaways:

  • Pepper can be an eco-friendly and effective solution for repelling mice due to the irritating effects of capsaicin.
  • It’s strong scent can block the smell of other attractants, naturally causing mice to steer clear of your area.
  • Effects can widely vary – if you have too many attractants (holes in the side of your house, tall grass, food lying around,) pepper won’t work by itself to get rid of mice.

Homemade Mouse Repellent Spray

In order to create your own homemade pepper repellent to keep mice away, you’ll first gather the following ingredients:

  • Dish soap: Used to make the spray stick to surfaces for long-lasting effect.
  • Spray bottle: For convenient application.
  • Hot peppers: To create the strong, repelling scent.
  • Cheesecloth: To strain the liquid before pouring it into the spray bottle.

Remember, your goal is to create a spicy, natural repellent that sends mice scurrying! You can substitute any of the peppers below while making sure to wear gloves while handling:

Peter Pepper10,000–23,000

In case you’re wondering, black pepper falls somewhere around the level of an Anaheim pepper but it’s not a chili pepper so it isn’t measured in SHU.


Step 1: Select several potent peppers like jalapeños or cayenne, and grind them into pepper flakes for a spicy base. Alternatively, you may use a few tablespoons of powdered cayenne pepper or ground black pepper. The more fiery the peppers, the more effective the repellent will be against mice!

Step 2: Mix the crushed pepper flakes with about 2 cups of water. If you’re using powdered pepper, aim for a ratio of one tablespoon of pepper to one cup of water.

Step 3: Bring the mixture to a gentle simmer on the stove, letting it cook for 20 minutes. This helps to release the essential oils from the peppers into the water, augmenting the potency of your repellent.

Step 4: Allow the mixture to cool completely. Once cooled, strain the solution through a cheesecloth or fine sieve to remove any large particles that could block your spray bottle.

Step 5: Add in a few drops of biodegradable dish soap to the strained solution. The soap acts as a surfactant, helping the pepper solution adhere to surfaces better, increasing its longevity. Ensure to mix the soap in while the solution is cool.


Once you’ve prepared your new pepper repellent, it’s time to put it to use:

Step 6: Pour the strained liquid into a spray bottle. This makes it easy to apply the mixture to targeted areas where mice tend to congregate or may enter your home.

Step 7: Spray the affected areas with the pepper repellent. Using gloves, focus on areas where you’ve noticed mouse activity or entry points. Be sure to reapply the spray every few days or after heavy rain to maintain its effectiveness.

Remember, the key to success in keeping mice away is using a potent spicy spray to irritate their sensitive noses and drive them away from your home.

Also, consider that there are other spicy substances you can use in your spray as well like, cayenne pepper, black pepper, hot sauce, paprika, or chili powder!

Other Natural Mouse Repellents

You know what they say, the zestier the flavor, the spicier the deterrent! While making pepper repellent is a hot choice for repelling mice, there are also other natural alternatives that you can consider for a mouse-free home.

Peppermint oil is my FAVORITE natural repellent. Specifically because I can get a preformulated spray in the form of Mighty Mint’s Rodent Repellent which contains peppermint oil as it’s main active ingredient. Peppermint oil is one of the most effective natural mouse repellents due to its pungent aroma.

Garlic is a powerful repellent not only for vampires but also for pesky mice due to its strong smell. You can crush some cloves and place them strategically around your home or even create a potent spray from minced garlic and water. The odor will have them running for the hills in no time!

Another stinky repellent is onions. Get ready to shed a tear or two, as these tear-jerkers have the potential to make mice scurry away. Place a fresh-cut onion in areas where mice are typically present and replace it regularly since moldy onions are hardly what you want either.

It might be paws-itively weird, but used kitty litter can be an effective solution to bid farewell to your uninvited guests. Sprinkling it around the house will give mice the impression that a fierce feline friend is lurking nearby, encouraging them to search for safer grounds. Who knew those furry felons could be so valuable in the battle against mice?

Here’s a quick summary of some other popular DIY mouse deterrents:

  • Garlic: Crush or mince and place around your home, or create a spray from minced garlic and water.
  • Onions: Slice and place in areas where mice are present, replace regularly to maintain potency.
  • Used kitty litter: Sprinkle it around your house to give off the impression of feline presence.

Increasing The Effectiveness Of Your DIY Pepper Mouse Repellent

Sealing Mouse Entry Points

Seal up gaps and holes both inside and outside your home to keep mice out. Mice are sneaky little creatures that can squeeze through even the tiniest of openings (as small as 1/4in!)

For small holes, use steel wool—an oldie but a goodie. Apply caulk around the steel wool to hold it in place, or try using spray foam if you’re feeling extra crafty. Why steel wool, you ask? Well, it’s because mice can’t chew through it!

For larger holes, use materials such as lath screen or lath metal, cement, hardware cloth, or metal sheeting. You can also use spray foam because while mice CAN chew through it, they would literally have to eat so much of it that they won’t want to.

Maintaining Cleanliness

A clean home is a happy home, especially when it comes to keeping mice away. Keep your kitchen spotless by regularly wiping down surfaces, storing all food in airtight containers, and sweeping up crumbs.

Don’t forget about the clutter! Mice love hiding in piles of stuff, so make sure you keep your living spaces clutter-free. The more clutter around, the more it’s like a VIP lounge for mice.

Food Storage

Proper food storage is critical in preventing a mice party in your home. Store all food, including pet food, in airtight containers made of sturdy materials like glass or metal. No more munching on your cereal late at night, little rodents!

Pro tip: Keep your garden tidy and free from any rotting fruit or vegetables – a little-known fact is that these attract mice like it’s their favorite restaurant.

That’s All We’ve Got!

Making your own pepper repellent to keep mice away can be an effective natural method for homeowners looking to repel these pesky rodents!

Cayenne pepper and black pepper are key ingredients as mice absolutely hate the powerful spiciness they contain. You can create a pepper repellent by mixing cayenne pepper with water, which will become a potent deterrent.

To use the pepper mouse repellent, simply spray the mixture around your house, focusing on potential entry points and areas where you’ve noticed mouse activity. Remember, persistence is key when using natural methods, so the process may need to be repeated regularly for the best results.

Now, you might wonder, why does this spicy spray work? The answer lies in the science behind it. Mice have highly sensitive noses and are easily repelled by strong odors, such as the spicy scent of cayenne pepper. This sensitivity makes pepper a powerful tool in keeping mice away.

But don’t forget, there are other ways to repel mice with spicy sprays too! For instance, you could create a mixture using other hot peppers or spices, like chili powder or crushed red pepper flakes. The key is to experiment with different combinations and find the one that works best for you and your specific situation.

Using the power of spicy peppers, you’ll give these rodents a reason to avoid your cozy abode. So, grab your cayenne pepper and a spray bottle, and show those mice who’s boss!
