Myth Busting Natural Mice Repellents

Table of Contents

Mice repellents are used to keep mice away. Some people use sprays, traps, and chemical mouse killers. However, there are compelling and natural ways to repel mice as a mouse repellent.

Many people believe natural mouse repellent is a myth and doesn’t work. Ultrasonic sounds use a sound frequency that hurts mice ears, and mothballs have been known to rid mice. Yet, scents such as peppermint oil and cayenne pepper are smells that mice hate.

But, does natural mouse repellent work effectively?

Are There Natural Mouse Repellents That Work?

The short answer to whether natural mouse repellents work or not is yes. You can do many things as a homeowner to repel mice in the most humane way possible. Whether you’re trying to prevent mice from appearing, or you are trying to get rid of mice that already exist.

The damage that mice or rats cause can be costly to repair and cause significant health issues. Some natural repellents that will work for mice and rodents are:

  • Peppermint oil, cayenne pepper, and cloves
  • Ultrasonic sound
  • Mothballs
  • Ammonia
  • Kitty Litter or owning a cat
  • Aluminum foil

A sure-fire way to repel mice is to keep preventative methods in place, such as keeping your home tidy, sealing holes, and maintaining house repairs. While natural repellents will work, some tactics have an expiry date on how long they’ll last. For example, ultrasonic sound may be more appropriate to repel rather than rid.

Will Mothballs Keep Mice Away?

Yes, mothballs will keep mice away due to the pesticide ingredients known as naphthalene or paradichlorobenzene, which are toxic fumes released into the air. While mothballs are an effective method to stuff into mouse holes or other cracks along a foundation, it’s best to put them outside.

Since mothballs give off a fume, you may become nauseous, dizzy, and get a headache, among other health-related symptoms, if exposed to the ingredients for long periods. You can place mothballs in areas such as:

  • Closed dresser drawers
  • Closed containers
  • Inside clothes pockets
  • Cracks or holes of the house outside
  • Any tightly contained area

If you place mothballs outside, ensure that you are not placing them in soil or water as the fumes will contaminate these exterior places.

Can You Use Peppermint Oil to Repel Mice?

Mice are repelled by many scents, including peppermint, cinnamon, vinegar, and ammonia. However, some of these scents are poisonous to house pets, so keep that in mind when using scent-deterrent sprays and repellents.

If you do not have pets, you can use peppermint oil or mint leaves almost anywhere with anything such as:

  • Cotton balls
  • Essential oils (drops on the ground along baseboards)
  • Peppermint spray (diluted with water)
  • Diffusers

Most scent-repellents work to prevent mice from coming into your home; however, there is not enough evidence stating peppermint oil and other scents get rid of a mouse infestation.

Do Ultrasonic Rodent Repellers Work?

If you’re looking for an immediate fix to rid your home of mice, ultrasonic repellents work – but only for a short time. Mice use scent-tracking for survival. They will travel as far as twenty feet to get food, bedding, and other items for their nests.

While the ultrasonic device may work for the first month, mice are very resilient and get used to the sound over time. The best thing you can do with an ultrasonic rodent repeller is to wait a week, then use other natural methods (mentioned) for preventative measures.

How to Repel Mice

While you can use mothballs, peppermint oil, and ultrasonic devices to rid your home of mice, the trick is to prevent the infestation before it happens. Mice reside in walls and can cause lots of damage to your home.

Tips to prevent and rid your home of mice include the following:

Keep Your Property in Good Repair

Check that your property has no small holes, cracks, or foundational damage along the exterior of your house. It is also good to keep pipes tight and check for leaks or clogged drains, as mice and rodents like to hide in moist areas.

Other things to keep in mind are:

  • Repair window screens or sills
  • Keep chimney vents closed
  • Install door sweeps on exterior entrances
  • Fix any pipe damage

Seal Small Holes

Any holes located outside need to be covered with scented cotton balls or mothballs that serve to repair any crack or damage. Gaps and holes are mainly found in:

  • Attics or basements
  • Between wall and floor junctures
  • Inside corners of your closets
  • Kitchen cabinets
  • Behind stoves, fridges, and other large appliances
  • Pipes
  • Electrical, plumbing, or gas lines
  • Around windows and doors
  • Within the foundation of your home
  • On the roof

Keep Things Clean and Tidy

One of the main things you can do to rid mice and as a preventive measure is to keep your interior and exterior tidy. Mice travel short distances for their resources for survival, so the cleaner your place, the fewer chances for their survival.

Ensure that you:

  • Sweep, mop, and vacuum regularly
  • Store firewood at least twenty feet away from your house
  • Clean up all garbage, food, and recycling products covered and neat outside
  • Always sweep after meals
  • Clean with bleach or ammonia once or twice a week

What to Do If You’re Still Having Issues With Mice

While there are only so many techniques you can do to keep your home a mouse-free zone, it’s not always possible to rid them entirely after an infestation has started. In cases where you find you’re still having issues with mice and rodents, you can call exterminators to rid your property of these damage-causing pests.
