You might enjoy the refreshing scent of peppermint, but mice absolutely can’t stand it. A few drops of peppermint oil on cotton balls placed around your home can work wonders. Not only will your home smell minty fresh, but it will also be mouse-free. Make it a habit to replace the cotton balls every few days to maintain its effectiveness.

2. Mothballs: The Old-School Solution

Mothballs are an old-school but effective solution to keep mice away. Despite being primarily used to protect clothes from moths, the strong smell of naphthalene in mothballs is a powerful deterrent for mice. However, remember that mothballs are toxic and should be kept out of reach from children and pets.

3. Ammonia: The Pungent Mice Repellent

If you don’t mind a bit of a pungent smell, then ammonia can be an effective mice deterrent. Mice mistake the strong smell of ammonia for predator urine, which scares them away. However, like mothballs, ammonia can be hazardous if mishandled, so use it with caution.

4. Clove and Cayenne: A Spicy Solution

Who knew mice had such a dislike for spicy smells? Mixing cloves and cayenne pepper can create a powerful scent that can send mice packing. Sprinkle this spicy mixture around the areas where you’ve noticed mouse activity for best results.

5. Citrus Scents: The Fresh and Fruity Deterrent

If you’re looking for a more pleasant-smelling mouse deterrent, then citrus scents are your answer. Mice find the smell of citrus fruits like oranges and lemons very off-putting. You can use citrus essential oils or even the peels of these fruits to keep mice away.

6. Eucalyptus Oil: The Australian Answer

Another essential oil that mice detest is eucalyptus oil. It’s a natural and non-toxic way to deter these rodents. Moreover, the fresh and uplifting aroma of eucalyptus oil can also help to create a calming atmosphere in your home.

Bay leaves are commonly used in cooking for their unique flavor, but they can also serve as a natural mouse deterrent. Mice dislike the smell of bay leaves, so scattering a few around your home can keep them at bay. Plus, they’re safe to use around kids and pets.

Vinegar might not be the best smelling solution on this list, but it’s certainly effective. The strong, sharp smell of vinegar is very off-putting to mice. You can use it by soaking cotton balls in vinegar and placing them in areas where you’ve seen mouse activity.

9. Onion: The Eye-Watering Deterrent

Onions are another potent mouse deterrent. Their strong smell can keep mice away, but remember to replace the onions before they rot to avoid attracting other pests. Be careful if you have pets, as onions are toxic to some animals.

Garlic isn’t just for keeping vampires away; it’s also effective against mice. The strong smell of garlic is something that mice find unbearable. You can use garlic cloves, or if you want a less intense smell, garlic oil can also work.

11. Used Kitty Litter: The Fear-Inducing Fragrance

This one might sound odd, but it’s based on a simple premise: mice are afraid of cats. The smell of used kitty litter signals the presence of a cat and can act as an excellent deterrent. However, this method might not be the most pleasant smelling solution for humans.

12. Essential Oils Blend: The Customizable Repellent

Why stick to one scent when you can create a blend? Mixing different essential oils like lavender, peppermint, and citrus can create a unique aroma that’s pleasant for you but repelling for mice. Plus, it’s a great way to customize the scent of your home.

13. Camphor: The Strong-Scented Solution

Last but not least, camphor is another strong-smelling substance that can keep mice away. It’s often used in religious ceremonies and for medicinal purposes, but its strong aroma can also deter mice. However, like mothballs and ammonia, camphor should be used with caution as it can be toxic if ingested.

So, there you have it, 13 smells that can keep mice from entering your home. While these methods are effective, remember that the best way to deal with a mouse problem is to prevent it in the first place. Keep your home clean and seal any potential entry points to keep mice out. If the problem persists, don’t hesitate to seek professional help. Also, remember that not all methods will work equally well in all situations. It might take some trial and error, and a combination of different tactics, to find what works best for you. The key is to be persistent and patient. Good luck!
