Ultrasonic Pest Repellers Buying Guide

What Are Ultrasonic Pest Repellers?

How Do They Look?

Don’t let its name intimidate you.

Ultrasonic pest repellers are easy to use devices. You can plug it into any electrical outlet. They are seldom bigger than the size of your palm and come real handy and sleek these days.

They are portable in any part of the world. There is not much repair or maintenance involved. Its super low pricing goes well with replace once damaged scenario.

What Do They Do?

These devices emit sound of short wavelength and high ultrasonic frequency.

Technically, these are sound waves with a ultrasonic frequency higher than 20,000 Hz. Being too high in pitch it cannot be heard by humans.

Though, we don’t hear these sounds, the pests can hear them. It annoys them to come anywhere in the range.

The ultrasonic repellents can drive away mices, rats, other rodents, and even insects.

There is no harmful chemical involved.

Some frequency range can be heard by pets and even children. Nevertheless, no reputable brand and their products operate at such a risky range. Its efficacy proved during testing bulldozes the questions over its theoretical proof.

How it Was Created?

The concept of ultrasonic pest repellers dates back to thousands of years.

It was in ancient China, they used manually operated devices to emit repelling sounds. Such techniques worked best to drive away pests and bugs from their crops.

Through the years, we acquired more knowledge about sound waves.

We now have electrically powered devices that are capable of emitting sound waves of higher frequency range. Today, ultrasonic best pest repellers come under the broad category of electronic pest control. The sector is consistently undergoing huge advancements as of now.

With reputable brands entering this space, it has a lot of scope.

How Do Ultrasonic Repellers Work?

Evidently, ultrasonic repellers make use of audible sound to drive away pests. Indeed, it is inspired by the age old Chinese approach. By definition, ultrasound means sound frequencies beyond human hearing levels. It has been used in pest control for the last few decades. Its designs vary by signal intensity, pricing and frequency.

Though these sounds are inaudible to the human ears, they can annoy pests.

In its range, it keeps the pests away. A significant amount of testing has already been done in this space. The sounds in the specified frequency range have been proved to drive away household pests, especially rodents.

Contrary to the popular belief, ultrasound cannot be heard by birds.

The ranges that overlap with kids and pets hearing ranges are avoided by repellers. That’s the first step taken towards curbing the side effects. Moreover, there are no harmful chemicals involved.

All you need is the device and an electrical outlet to plug the device in.

Since, they don’t come with batteries, you need constant current supply.

Upon plugged into an electrical outlet, the device can emit high frequency sounds.

Some repellers allow controlling the range on frequencies.

The sound causes an audio genic seizure response. It results in convulsions, random running and possible cerebral death in pests. This is exactly why ultrasonic pest control repellers scores excellently in efficacy testing.

The theory behind ultrasonic devices is as simple as 1-2-3.

The confused rodent flees when disturbed by ultrasonic sound waves. They flee from breeding, gathering food and building nests. Because of the ease of use, these devices appeal to just about anybody. Together with traps and other methods they effectively eliminate the rodent infestation.

Ultrasonic Pest Repeller Side Effects

Humans cannot hear sounds emanating from ultrasonic devices.

Nevertheless, our furry friends are able to hear that. Dogs in particular, hear sounds at much higher frequencies than humans. Thus, they can pick such ultrasonic frequencies from pest repellers.

Your dog wouldn’t necessarily be bothered by it.

However, the ultrasonic sound can cause a bit of unease. It really depends on how suited your pooch is to its habitat.

Every dog responds to sounds differently.

From its bodily signs, you can understand whether it has heard the emanated sounds.

From whining to backing away to running down the lawn, the dog can respond in any way possible. The bodily signs also give you a clue on how much your pet agrees with this pest treatment. Most often than not, the dog is curious or not bothered with it at all.
Top brands produce pet friendly pest repellers only.

Moreover, ultrasound waves don’t annoy dogs like it does with pests.

The former logic applies well with cats, ferrets and cattle as well.

Unfortunately, smaller pets like hamsters, guinea pigs and other rodents are vulnerable. Check with your local veterinarian before getting the best ultrasonic pest repeller.

A great way to safeguard your vulnerable pets is by creating safe houses.

  • Considering ultrasonic sound doesn’t pass furniture or drapes, establish safe zone using them as building materials.
  • Try targeting pests based on region.
  • Limit targeting to attics, kitchens, sheds, basements and pantries.
  • Ensure as much area is covered to improve efficacy and curb side effects.

Some users wrongly complain repellers attract more pests. Some repellers take a few weeks before driving pets off your property. First they disturb pets and make them come out of their hiding spots. In following weeks, they make pets flee the place. Understand the nature of device prior to purchasing it.

How to Choose a Good Repeller?

There are a few factors you must consider when choosing the best ultrasonic pest repeller:

  • Range: Distance covered is the first factor you must consider when choosing ultrasonic repeller.
    It helps improve efficiency as well as saves money. Invest in a repeller that offers wide coverage.Most ultrasonic repellers cover 80 – 1200 square feet.There are some powerful units that have a whopping range of up to 5000 square feet.To improve range you can also opt for corded repellers. Nevertheless, plugins are perfect if you are required to cover smaller spaces.
  • Costs: Like in all products, pricing matters.
    For starters, ultrasonic repellers are inexpensive by default. There is no need to shell out too much cash.However, price varies with design, brand, size and range.Generally, plug-ins is affordable compared to corded repellers. For instance, most plug-ins can be brought for just $10. Brands sell them as a packet of 5 usually.Repellers with advanced features and additional options cost a bit more.
  • Safety: Ultrasonic repellers don’t contain harmful chemicals.
    Even, then there exists a safety checklist. Ensure that the frequencies are kid-friendly and pet-friendly.Plug-ins is comparatively safer, but they cover a small range.Observe the behavior of your pets and keep constant surveillance.Work on safe houses for domesticated rodents such as guinea pigs and rabbits.Always check out for warnings in the product manual. Never ever invest in low quality products. Some of the badly managed frequencies can even reach hearing range of few adults and children.


Summing it up, you need to choose the right ultrasonic pest repeller based on your needs.

  • Firstly factor in the type of settings you need to work with.

An indoor plugin will not work as effectively on the outdoors. Similarly, a corded outdoor repellent is little too excessive for indoors. Additionally, you need to factor in the range as well as the type of pests you are dealing with. It should solely be based on personal preferences.

  • If you have pets, frequency limits becomes your top priority.

Your lifestyle has a major say on what type of pest repellent you need. It has a say on whether you need one or not as well. If you have issues at cluttered areas, you need multiple pest repellers. Usually, the indoor plugin type repellers come in a pack of 4-6.

  • Prior to purchasing the ultrasonic repellers, understand its mechanism.

Learn about how various frequencies work and how it affects kids and pets. Some of the repellers have advanced options.

  • Learn every single option before starting to use the device.

  • Some of the devices may not start driving pests right away.

They might take several weeks before showing results. If you do not want it, choose a quicker alternative. The delay involved in some of the repellers is the reason why the efficacy is wrongly questioned. It reflects in the misinformed reviews stating that the repellers attract more pests. Hence it’s important you know how the mechanism works in your device.
