Mice can be a bothersome pest in homes and businesses. They damage property, contaminate food, and spread diseases. Getting rid of mice can be a challenge, but using natural repellents like peppermint oil is an effective and safe method. Here’s a deep dive into using peppermint oil to deter and control mice.
What Is Peppermint Oil and How Does It Repel Mice?
Peppermint oil is extracted from the peppermint plant, a hybrid of water mint and spearmint. It has a strong, invigorating peppermint aroma and flavor.
The active ingredient in peppermint oil is menthol, which gives it its distinctive minty smell and taste. Menthol is a strong smelling compound that mice dislike.
When mice encounter the potent menthol scent of peppermint oil, it overwhelms their sensitive respiratory systems and drives them away. Mice also find the taste of menthol unpleasant. Peppermint oil is a natural, non-toxic way to repel mice and prevent infestations.
Benefits of Using Peppermint Oil Over Toxic Chemicals
There are many benefits to using peppermint oil instead of toxic rodenticides and pesticides:
- Non-toxic and safe for humans, pets, and the environment
- Natural and organic – extracted from plant materials
- Doesn’t kill mice but deters them from entering an area
- ** Pleasant smell** for humans compared to harsh chemicals
- Cost effective especially when diluted in water
- Easy to apply by spraying or wiping onto surfaces
Peppermint oil provides a safer alternative to dangerous poisons and traps. With some simple preparation, it can be an excellent part of an integrated pest management plan.
Preparing and Diluting Pure Peppermint Oil
100% pure peppermint essential oil is highly concentrated and should be diluted before use as a pest repellent. This helps the oil cover a larger area and saves money.
Follow these steps to easily dilute pure peppermint oil:
What You Need:
- Pure peppermint oil – food grade or therapeutic grade
- Water – distilled or boiled and cooled tap water
- Spray bottle, jar, or jug
- Measuring spoon, cup, or graduated cylinder
- Funnel (optional)
- Stirrer like a chopstick or spoon
Instructions:
- Measure out the amount of water needed into the container. A good starting ratio is 1 part peppermint oil to 3 parts water. For example, add 1 cup of water to a spray bottle.
- Using the measuring spoon, add 1-2 teaspoons of peppermint oil per cup of water, depending on strength desired.
- Insert the funnel into the mouth of the spray bottle or jar (optional). Carefully pour the oil into the container.
- Replace cap and seal tightly. Shake vigorously for 30 seconds to mix the water and oil together.
- Always shake well before each use to disperse the oil through the water.
- Label container with contents and date prepared. Store out of sunlight and extreme temperatures.
Tips:
- Use glass, stainless steel, or PET plastic containers – peppermint oil can degrade plastic.
- Start with a weaker dilution and increase strength if needed.
- Add a few drops of mild eco-friendly soap to help emulsify the oil.
- Refrigerate for an extra strong cooling minty blast!
Now the peppermint oil is ready to use to repel those pesky mice!
Where to Apply Peppermint Oil to Repel Mice
Strategic application is key when using peppermint oil for mice control. Concentrate on areas inside and out where mice enter, hide, and travel through your home or building.
Apply these solutions in and around these key areas:
Entry Points
- Along the outside foundation and walls
- Near doors and windows
- Under and around sinks and refrigerators
- Crack and holes in walls, floors, cabinets
Nesting Sites
- Attics and crawl spaces
- Inside cabinets and closets
- Garages and sheds
- Junk piles and clutter
Travel Routes
- Along countertops and baseboards
- Behind appliances and furniture
- Inside drawers and storage boxes
- Around pipes and wiring
Focus on sealing up cracks and holes with steel wool or caulk to block access. Then apply peppermint oil to repel mice away from entry hot spots.
5 Easy Methods to Use Peppermint Oil for Mice
There are several effective and easy ways to use peppermint oil concentrate or solution to prevent and get rid of mice at home.
1. Peppermint Spray
This is the most common method. Use a spray bottle to apply diluted peppermint oil along baseboards, countertops, shelves, and other surfaces. Spray around entry points and anywhere mice may travel. Reapply every few days.
2. Scented Cotton Balls
Soak cotton balls in diluted peppermint oil. Place them along shelves, in drawers, under sinks, inside wall voids, and anywhere else mice may hide. Replace once a week.
3. Repelling Sachets
Add peppermint oil to small sachets or packets. Hide them under and behind appliances and furniture. Can also place near pantry foods to repel mice.
4. Peppermint Soaked Rags
Wet rags, strips of cotton tee shirts, or cheesecloth with the diluted oil mixture. Stuff them into gaps and holes where mice may enter. Replace periodically.
5. Mix with Other Dry Items
Add several drops of peppermint oil to materials like steel wool, nuts shells, or sand. Mice dislike the sharp texture and smell. Use this mix to fill holes and deter nesting.
Always monitor areas for signs of mice after applying. Look for new droppings, chew marks, tracks, grease marks along walls, and live mice. Refill, re-spray, or reapply as needed.
Tips for Using Peppermint Oil to Repel Mice
Here are some useful tips and precautions when using peppermint oil for controlling mice:
- Test for oil staining before widespread use. Apply a few drops on a small hidden area and check back after a few hours.
- Avoid getting pure peppermint oil on surfaces like wood, plastic, and leather which may be damaged.
- Never spray peppermint oil directly onto mice or nests with young mice. This can be inhumane.
- Use the lowest concentration needed to repel mice. Start with a 10% solution and increase up to 50% if required.
- Open windows or use fans when applying larger amounts to avoid overwhelming odors. The smell dissipates quickly.
- Reapply peppermint oil every 2-7 days since the scent fades over time. More frequent applications may be needed.
- Combine peppermint oil with other deterrents like equipment that emits high frequency sounds.
- Always clean up any food spills, crumbs, and trash. Removing food sources helps repellents be more effective.
- Inspect for and seal cracks, holes, and gaps where mice enter. This keeps new mice from easily gaining access.
With smart application and monitoring, peppermint oil can drive mice away from structures effectively and safely.
Will Mice Eventually Get Used to the Smell?
An important question about using peppermint oil is whether mice will eventually become accustomed or desensitized to the minty smell after prolonged exposure.
There is conflicting evidence about this:
- Some studies have shown that mice and other rodents can adapt to certain odors and scents over time. Their olfactory nerves may become less sensitive after repeated exposure.
- Anecdotal reports however indicate that mice don’t seem to develop a tolerance or become used to the strong smell of peppermint oil, even with long term use.
To ensure peppermint oil remains effective for mice control, it’s smart to:
- Use higher potency oil and change up concentrations
- Rotate between different essential oil scents
- Combine with other deterrent methods
- Reapply frequently and to new locations
- Clean up other attractants like crumbs and clutter
Routinely using peppermint oil along with good sanitation practices will provide the best defense against persistent mice.
Are Mice Harmed by Peppermint Oil?
An important concern when using peppermint oil is whether it can humanely repel mice without harming them.
Here are some considerations about peppermint oil safety for mice:
- Peppermint oil is non-toxic to mice when used correctly at proper dilutions. Ingesting large amounts of concentrated oil could be harmful.
- The strong menthol odor causes temporary respiratory distress but does not injure mice when applied in open areas.
- Avoid over-saturating confined spaces like walls with peppermint spray, as this could be dangerous.
- Never spray pure peppermint oil directly onto mice or trap them in enclosed spaces with high concentrations.
- Monitor areas after application and provide escape routes. Look for signs of distress like mice clustering in corners.
- Read product labels and follow all instructions for dilutions and safe usage around pets and humans.
When used properly, peppermint oil can humanely and effectively deter mice from an area without inflicting harm. Combining it with sealing up entry points guides mice to leave while preventing new ones from entering a home or building.

Planting Peppermint Plants to Repel Mice Naturally
In addition to using the oil, consider planting peppermint plants around your home’s exterior. Mice tend to avoid areas with growing mint.
Plant peppermint in garden beds, window boxes, or pots near potential entry points like foundation vents, crawl space entrances, and gaps around pipes. The roots release natural menthol as they grow.
Choose compact peppermint varieties like ‘Minymint’. Keep the plants pruned to encourage fuller growth. The smell from fresh mint growing near doors, vents, or openings can deter mice from approaching.
Crush fresh leaves often to release more menthol fragrance. Prune mint regularly so it doesn’t spread out of control. Planting peppermint is a natural, decorative way to deter mice.
Tips for Maintaining an Effective Peppermint Oil Mouse Repellent Strategy
Here are some useful tips for keeping your peppermint oil mouse control plan effective long-term:
- Check areas frequently for signs of mice and reapply or respray as needed
- Alternate between different essential oil blends to prevent mice adapting
- Combine peppermint oil with electronic repellents and natural deterrents
- Seal up cracks, holes, and entry points after repelling mice to prevent newcomers
- Identify and remove food sources and clutter that attract mice
- Maintain tidiness, frequent trash removal, and regular cleaning in problem areas
- Consider adopting a cat – mice are instinctively afraid of feline predators
- Replace weather stripping around doors and windows if worn out or ripped
- Keep repellent containers sealed tight and out of direct sun to prevent oil fading
- Replenish cotton balls, pouches, and rags placed in enclosed areas
