Natural mouse repellents

Quick facts about natural mice repellents

  • Peppermint oil may temporarily repel mice; it does not get rid of them permanently
  • Mothballs do not effectively repel mice; the amount needed could pose a risk to human health
  • Ultrasonic mouse repellents are not reliably effective
  • The most effective way to get rid of mice is through professional pest control

Natural ways to get rid of mice are everywhere online. From essential oils to mothballs, many people try home remedies to fix a rodent problem. But does peppermint oil repel mice? And if so, is it enough to resolve a full-blown infestation?

While some natural repellents might show short-term results, they often don’t tackle the root cause. It’s important to know which mouse repellents work, what’s a myth, and what could make the problem worse.

What are the risks of using natural mouse mice repellents?

Natural mouse repellents can sometimes work, but you shouldn’t depend on them. There are risks to consider with DIY solutions.

The more time wasted on attempting to get rid of mice with natural deterrents, the more time your mice have to breed and multiply. (A pair of mice can produce up to 2,000 offspring in a year.) The risk of food and water contamination also increases over time through increased exposure.

You need to know where to place your natural repellents for them to be the most effective. This is where having a basic knowledge of mouse behavior comes in handy. If you know where mice tend to commonly hide inside homes and what attracts them at night, you can better decide where to sprinkle your cayenne pepper or other natural ‘weapon’ of choice. Even if you achieve success and the mice leave, how do you know they will not return again?

Even after you repel mice, you need to prevent them from getting into your home again. Part of a permanent solution – natural, professional, or otherwise – must include the task of proofing your property against any further infestations.

 

There are many myths surrounding which DIY mouse control techniques work the best to help evict your unwanted house guest. But how do you get rid of mice effectively? If you have questions about mice or have an infestation, contact your local Ehrlich mice control technician and we’ll help get rid of them.

Natural mouse repellents

When you search for ways to get rid of mice, natural repellents often come up first. People try things like peppermint oil, dryer sheets, or even cat litter to make mice leave. These methods may have some short-term effect, but they rarely solve the problem for good. Mice are clever and will quickly adjust if they think the reward – food, warmth, shelter – is worth it.

Do mothballs keep mice away?

To put it simply: no. Mothballs are considered an efficient DIY mouse control method because they contain naphthalene. Naphthalene is a strong-smelling, solid white substance. When it is inhaled or ingested, it can cause blood cells to lose their ability to carry oxygen, which is why homeowners think mothballs are a great deterrent for mice.

However, the amount of naphthalene found in mothballs is small. It’s enough to deter moths and other insects, but for mice, it’s no problem.  There have been many cases where mice have walked over the mothballs, paying no attention to them whatsoever. The amount of naphthalene needed to deter mice would also be strong enough to pose a risk to humans.

What does peppermint oil do to mice?

The smell of peppermint oil disturbs mice and can help temporarily keep them away. Mice rely heavily on their keen sense of smell, and the strong scent of peppermint can be irritating and overwhelming to them.

Although peppermint oil can deter mice momentarily, it doesn't guarantee their removal. Mice are resilient creatures that can adapt to various scents, including those from unpleasant environments. While the oil may mask other odors, it is not a reliable solution for long-term pest control. For effective management, consider more comprehensive strategies.

Natural mouse repellents to avoid


Trying to fix a mouse problem with home remedies can do more harm than good. Some methods just don’t work, and others might even be risky to your health. Here are a few mouse repellents that you might want to skip.

Dryer Sheets

Some people believe that dryer sheets can keep mice away because of their smell. While the scent may annoy a mouse at first, it won’t stop them for long. Mice are determined and will return once the scent fades. This is not a reliable mouse prevention method.

 Ammonia

Ammonia smells like predator urine, which is why people think it will scare mice off. The truth is, using ammonia indoors can be harmful to both people and pets. And, as with other scents, mice can get used to it over time.

Cat Litter

Used cat litter is thought to scare mice because of the predator smell. But this can be messy and unsanitary. Plus, there’s no proof that it works. As with other remedies, mice may just learn to avoid the littered area rather than leave your home.

Ultrasonic rodent repeller

There are a handful of ultrasonic rodent repeller devices on the market. However, the truth is that none of these are very effective. One of the main issues when using an ultrasonic rodent repeller is the placement of the device. These repellers rely on electrical sockets to work. If there is no socket near where the rodent activity is in your home, the device will be completely ineffective. 

Mice are resilient, adaptable creatures. Much like naphthalene, the frequency of ultrasonic sound waves needed to successfully repel mice would be strong enough to cause damage and harm to humans and domestic animals as well.

Using an ultrasonic mouse repeller may work for a short period of time. That is, until the mouse learns to avoid the area affected by the ultrasonic sound waves, or simply adapts to the background noise.

DIY mouse prevention

There are some techniques you can use to secure your home and prevent any unwanted guest from making your property their home.

  • Repairs - Repair any damage, both exterior and interior. This will help prevent any mice from finding easy access to your home. 
  • Steel wool - Mice are known to be able to chew through almost anything, especially if they think food is on the other side. However, one thing they can’t chew through is steel wool. Fill any holes in your home with this material - gaps around air vents, holes in kitchen cupboards, etc.
  • Keep clean - Giving your house a good clean will help keep mice away. They have an amazing sense of smell so keeping food in airtight containers will make sure that these home-invading pests won’t follow the food scent to your home.

Ultrasonic rodent repellers release high-frequency sounds that mice find annoying, but they often don’t work well. Placement is key, and mice can adapt to the noise. For lasting results, it's better to rely on more comprehensive solutions.

Do mice hate peppermint? Does peppermint repel mice, or is it a myth? The truth is, the strong smell of peppermint oil can bother mice and possibly keep them away for a short time, but it doesn’t stop them forever. Mice can get used to the smell, especially if there’s food nearby. So while it might seem like peppermint oil keeps mice away, it’s not a long-term fix.
