Mice have an incredible sense of smell, which they use to find food, navigate, and even communicate. But this superpower can also be their downfall. Certain scents are so offensive to mice that they’ll steer clear, making them a valuable tool in your pest control arsenal.
Here at Rentokil, we’ve been battling mice for a century, so we know a thing or two about what makes them tick (and what makes them flee!). Here are some of the scents that mice find most repulsive:
1. Peppermint: The refreshing aroma of peppermint might be a delight to humans, but mice find it overpowering and unpleasant. Planting peppermint around your home or using peppermint oil in diffusers can help deter these furry intruders.

2. Cinnamon: This warm spice evokes images of cosy winter nights, but mice find its strong scent anything but comforting. Sprinkle cinnamon powder in areas where you’ve seen mouse activity or use cinnamon oil to create a natural repellent.

3. Vinegar: The pungent aroma of vinegar is a powerful deterrent for mice. Soak cotton balls in white vinegar and place them in areas where mice are likely to travel.

4. Cloves: The strong, spicy scent of cloves is another olfactory offender for mice. Place whole cloves or clove oil near entry points and areas where you’ve noticed signs of activity.

5. Bay Leaves: While bay leaves add a subtle flavour to our cooking, mice find their aroma overwhelming. Scatter bay leaves in cupboards, drawers, and other potential hiding spots.

6. Ammonia: The strong, pungent smell of ammonia is highly offensive to mice. However, use caution when handling ammonia, as it can be irritating to humans as well. Soak rags in a solution of ammonia and water and place them in areas where mice frequent.

7. Cayenne Pepper: The fiery heat of cayenne pepper is not just unpleasant for humans; mice also find its intense aroma unbearable. Sprinkle cayenne pepper in areas where mice are likely to travel.

8. Used Coffee Grounds: While we might enjoy the aroma of freshly brewed coffee, mice find the smell of used coffee grounds repulsive. Scatter used coffee grounds around the perimeter of your home or near entry points.

9. Mothballs: The strong, pungent smell of mothballs is a well-known deterrent for moths and other insects, and it also works on mice. However, use mothballs with caution, as they can be toxic to humans and pets if ingested.

10. Dryer Sheets: The fresh scent of dryer sheets might be appealing to us, but mice find it overwhelming. Place dryer sheets in areas where mice are likely to nest or travel.

Beyond Scents: A Comprehensive Approach to Mouse Control
While these scents can help deter mice, they are not a substitute for a comprehensive pest control strategy. To effectively control mice, it’s important to:
- Seal entry points: Mice can squeeze through tiny openings, so seal any cracks or gaps in your home’s walls, doors and windows.
- Eliminate food sources: Keep food stored in airtight containers and clean up spills and crumbs promptly.
- Remove clutter: Mice love to hide in cluttered areas, so keep your home clean and tidy.
