What Are Ultrasonic Pest Repellers?

Ultrasonic pest repellers are devices that emit a consistent noise at a frequency which is too high for humans to hear. These sound waves are designed to distract, annoy, and deter common household pests such as cockroaches, spiders, grasshoppers, and rodents.

Take a look a the below video to get a sense of what these devices look and feel like out of the box.

How Do They Work?

Ultrasonic pest repelling devices require electricity to function. It is plugged into an outlet and starts to emit a high frequency that is difficult for humans and other larger animals to hear.

The sounds and wavelengths released by the repeller is designed to cause a physiological response in pests.

The full name for it is an audiogenic seizure response.  The noise disorients the pest to the point where they begin to run in random directions, become confused, convulse, and eventually die from cerebral hemorrhaging. 

Do Ultrasonic Pest Repellers Actually Work?


The use of ultrasound to deter pests is a relatively new idea, although sound itself has been used as far back as Ancient China. Rodents suffer from noticeable affects from the ultrasound, but some studies found that creatures like spiders and ants simply don't care.

Other studies have found that pest repellers may actually ATTRACT mosquitoes!


If you're someone who wants to avoid chemical forms of pest control, then investing in an ultrasonic pest repeller could be right for you to at least try.

There are many accounts of people finding success with pest repellers, so I would recommend at least attempting to use them if you want to avoid chemical treatments.

Rodents and other small animals with sensitive hearing hate the noise and it should drive them away.

If you're facing pest problems and this repeller fails to do its job, then we'd recommend reviewing our pest killing products section to review your options for your specific pest situation.

How to Buy a Good Ultrasonic Repeller

Because consumer focused ultrasonic pest repellers have only recently hit the market in the last decade or so, there quite a few options available.

But how can you tell if you've found a good one?

Strength and Range of Your Repeller

Different devices use varying levels of ultrasonic waves. How high or low the waves are is called the frequency. The key to finding a reliable ultrasonic repeller is using one which has a frequency that won't affect you and your pets, but will prevent pests from infesting.

Devices with higher frequencies are less likely to harm other animals in your home, but will annoy and stop creatures like rodents from entering. 

Longevity of Your Repeller

Disposable pest repellers will not last as long as a more expensive model, which could last for years. These disposable models are less expensive but require frequent replacements because of their cheap design.

However, it's easier to purchase enough to fill multiple rooms. People who know they have one area which attracts pests should invest in a long-lasting model. Individuals who would rather have all-around protection during a short period of time can buy low-cost alternative repellers.

How to Use One in Your Home?

Ultrasonic repellers are simple to use. An individual either plugs the device into an electrical outlet or switches it on. The repeller should be placed in a location where its noise will not be affected by walls and furniture.  Ultrasonic waves transmit at an extremely high frequency.

The waves can be stopped or suppressed by solid objects, which is why it's important to have the repeller facing an open area.

Can You Use a Repeller For You Car?

If you live in a wooded area with lots of trees and shrubbery, you might have a problem with chipmunks, mice, and rats trying to nest inside your car.

Some ultrasonic repellers are specially made to be placed under your hood to keep these rodents out . The Installation is slightly more technical, but nothing a normal car owner couldn't handle after reading through the directions.

Take a look at the below video for an example of a repeller being installed inside a car.

How to Protect Pets From Side Effects?

Many people are naturally worried about the safety of their pets when using an ultrasonic pest device.

Studies found that cats and dogs, although they can hear the waves, are unaffected by low exposure to them.

Rodents such as pet mice, hamsters, and rats should be kept away from rooms that use the device because they can hear the noise and will be disturbed.

The difference comes from the fact that dogs and cats can't hear as high of frequencies as many rodents.
