Key Facts

  • The #1 Best Overall mice repeller is the Neatmaster Ultrasonic Pest Repeller.
  • When you’re shopping for an ultrasonic mice repeller, consider the kind of infestation (mild or serious), location of infestation (indoors, outdoors, or automobile), features, and price.
  • Towards the end of this review, we explain why mice take up residence in homes and automobiles and provide lists of natural remedies and other methods of eradication.

Mice carry many dangerous diseases and can cause serious damage to your home or even your car. So, once it seems like you have an infestation, you must act fast. In fact, why wait? If you notice even one mouse, it’s time to take action before it becomes many mice.

Manufacturers of ultrasonic mice repellers make a lot of claims about these devices. They promise you can get rid of mice and prevent them from returning. Some even claim that one device can help to solve all your pest problems.

Are these claims true? How do ultrasonic mice repellers work? We took an in-depth look at these products and their many controversies. We also share some of the best models and their features so you can decide whether they’re right for you.

Do They Actually Work?

There are many controversies surrounding the use and effectiveness of ultrasonic mice repellers. Lab testing shows mixed results while manufacturers and many customers swear they work.

The technology behind the use of ultrasonic mice repellers has existed for quite some time. In fact, it dates back to the ancient Chinese. They used ultrasonic frequencies which are above the human hearing frequency, to keep rodents from crops and agricultural buildings.

Most ultrasonic mice repellers work this way. Humans can detect noise at frequencies around 20Hz to 20kHz. Mice, on the hand, can hear frequencies ranging from 1Hz to 100kHz. Ultrasonic mouse repellers emit sound at a frequency higher than 20kHz or lower than 20Hz. Mice can hear them, but humans cannot.

This sound that mice can hear causes confusion and disrupts their activities, such as nesting, breeding, and gathering food. The sound may also prevent them from communicating, since scientists believe that mice communicate at a frequency that is also higher than human hearing.

So, do these devices work or not? Well, many buyers swear they got results using them. That’s why we’ve decided that it’s up to you to research and determine whether to use them. The truth, however, remains that it’s best to arm yourself in whatever way possible when it comes to mice.

So, if that includes combining ultrasonic mice repellers with other forms of mice repellents, go ahead. The goal is to get rid of the mice permanently. Now that we have that out of the way, here are some top-rated ultrasonic mice repellers we found that you can try.

How to Choose the Best Ultrasonic Mice Repeller

Kind of Infestation

Is your infestation mild, or is it serious? Serious infestations call for more stringent measures that some ultrasonic mice repellers may not be able to handle. Our best overall repeller, however, has functions for serious infestations, so you can try that out.

Location of Infestation

Some ultrasonic mice repellers need a place to plug in, which might make them inefficient outdoors. You also won’t be able to use them in places without constant electricity and an outlet. That’s why we included the battery-powered options, which you can use anywhere to eliminate mice. Also, some mice repellers are designed to be used in automobiles.

Features

Some repellents come with features like light and the ability to vary the frequency you want to use. You can take a look at these to find which will work best for you. Some repellents also come with a standby function which is great for those looking to repel mice from their car.

Price

Mice cause a lot of damage, so it is important to get remedies that do not bleed you dry too. That’s why we have a “Best for Affordability” option. Most of the ultrasonic mice repellers in this list are also moderately priced.

Why Do Mice Enter Our Homes?

Mice come into homes for food, water, shelter, or warmth. Since these are undoubtedly available in your home, there’s a chance that mice will try to move in.

Natural Remedies for Mice

Most times, it takes using more than one method to get rid of mice. So, it doesn’t hurt to add a few natural home remedies while using an ultrasonic repeller. Here are some natural remedies that could also prove effective in getting rid of mice:

  • Onions: Mice do not like the strong smell emitted by onions. As a result, homeowners who do not mind the smell can use these to chase the mice away faster. Just cut and put them in spaces and holes that mice use. You should be ready to switch these out when they begin to rot.
  • Black Pepper: Black pepper uses the same smell concept to chase mice away. To use this, sprinkle them on pathways that mice use and in nests if possible. If you find suspicious cracks, you can also use these there. The choking smell will drive the mice away.
  • Essential Oils: People love to use essential oils to repel mice as they smell very pleasant to humans. Picture your home smelling like peppermint oil while keeping the mice away. It’s an attractive option. Other essential oils that also work include citronella oil, mint, and lemon oil. The smell, while nice for us, is too strong for mice who have a very keen sense of smell. This chases them away.

Other Mouse Control Options

For a serious infestation, experts advise using more than one control method to get the best results. So, if you’re trying to get rid of mice, here are some other effective ways:

Traps: Traps help you catch mice around your home so that you can get rid of them. Some of these kill the mice instantly, while others only trap them so you can get rid of them yourself. Examples of traps include snap traps, glue traps, and electric traps.

Poison: While poisoning mice using bait is effective, most homeowners avoid this method. This is because, with this, you have no control over where the mice die. It can be in hard to reach places where the smell can linger. It, however, does work and can effectively eradicate mice from your home.

Ultrasonic Mice Repellers: Do They Actually Work? FAQs (Frequently Asked Questions) 

Do ultrasonic rodent repellents actually work?

There are many conflicting studies where this is concerned. However, they all agree that mice can hear ultrasonic sounds, which is the concept of these repellents. We advise conducting personal research before using any product, including the ones in this review.

What is the most effective mouse deterrent?

There are many ways to deter mice from your home. They include using traps, poison, natural remedies, and ultrasonic repellers. Traps are really effective as they use bait to lure the mice and catch or kill them, thus efficiently reducing the population.

Do mice get used to ultrasonic pest repellers?

Mice can get used to an ultrasonic pest repeller if only one frequency is used. That is why the repellers on our list mostly use variable frequencies and sharp outbursts to prevent mice from getting familiar with the sound.

Is there a sound frequency that repels mice?

Mice are very sensitive to sound and can hear a wider range of frequencies than humans. They also hate the frequencies produced by ultrasonic mice repellers, although humans cannot hear these.

Do sonic waves work on mice?

Studies show conflicting results regarding the work of sonic waves on mice. This is why we advise that homeowners research before making a purchase. You can also combine more than one mouse repelling option to get rid of mice.
