In this brief guide, we’ll teach you a thing or two about ultrasonic bed bug repellers, how to find the best unit for your home, and what the top ultrasonic bed bug repellers are on the market.

Pests are a source of incredible distress at home, at the office, and anywhere else they reside (virtually everywhere). Bed bugs are especially bothersome since they appear out of nowhere and are virtually impossible to get rid of. Be careful when dealing with bed bugs since their bites can lead to infections like impetigo, ecthyma, and lymphangitis.

If you’re reading this, you’re probably at your wits’ end on how to deal with bed bugs once and for all. You might have tried vacuuming, steam-cleaning, or using UV-C rays, but there’s one device you might not have heard of: ultrasonic bed bug repellers.

Ultrasonic Bed Bug Repellers – What To Look For?

Here’s a quick guide on what important features and specs to look for in the best ultrasonic bed bug repeller.


The strength of an ultrasonic bed bug repeller refers to the soundwaves it produces. Ultrasonic bed bug repellers typically produce between 25 kHz and 65 kHz, though it might prove more effective to find a model that produces a higher maximum frequency. Humans can hear up to 25 kHz, so even the weakest ultrasonic bed bug repeller should be inaudible.


Ultrasonic bed bug repellers have a finite range of between 1,000 and 6,500 square feet. Ideally, you’ll want to place at least one ultrasonic speaker in every room that’s infested with bed bugs or other pests. Just make sure that the device’s speaker can reach all four corners of the room.

 Number of devices per pack

Finding a multi-speaker pack will let you place a speaker in more than one room. The soundwaves produced by these devices cannot penetrate solid objects, so you’ll need more than one to provide enough coverage for an entire floor or home.

 Built-in Ionizer

Some of the fanciest ultrasonic speakers come with a built-in ionizer to slightly improve indoor air quality. However, the ionizing function can produce ozone, a lung irritant that can lead to respiratory problems when exposed to the molecule for lengthy periods and in large doses.

If you activate the ionizer feature, make sure no people or pets are present in the room and only come back after waiting a couple of hours for the ozone to dissipate.

What Are Ultrasonic Bed Bug Repellers?

An ultrasonic pest repeller is a device that emits noise constantly at a high frequency. These sounds are inaudible to human ears, but bed bugs are rodents supposedly can’t bear them. The purpose of the sound waves is to annoy and deter household pests from getting into your home.

How Does An Ultrasonic Repeller Work?

To use an ultrasonic bed bug repeller, all you need to do is plug it into a wall outlet. It’ll emit high-frequency noises upon starting up, which are inaudible to humans and large mammals. The wavelengths that the ultrasonic bed bug repeller produces will allegedly trigger a physiological response in pests known as audiogenic seizures.

The noise annoys household pests to the point that they’ll begin scattering in random directions. They can become disoriented and convulse, making it easier to remove them from our homes and offices. Most of the time, the pests will make a beeline straight out of the door to avoid the high-pitch noises, but based on some reports, certain pests can die from cerebral hemorrhaging from prolonged exposure.

Does Ultrasonic Bed Bug Repeller Works?

Sometimes. That’s probably not what you wanted to hear but please, bear with us.

Although sound has been the weapon of choice to deter pests in Ancient China, ultrasound bed bug repellers are a relatively new invention. However, studies on the subject matter date back to the 1980s.

A study conducted in 1984 was set out to see whether commercial ultrasonic devices had any effect on cockroach activity. It turned out that cockroaches preferred being in areas without ultrasonic frequencies.

In 1985, a group of researchers tried five different devices that emitted frequencies of between 20 and 70 kHz to gauge how effective they were in deterring mosquitoes. Not a single one of them succeeded.

As for bed bugs, those critters that are known for being borderline impossible to eliminate, a 2012 study concluded that bed bugs showed indifference to areas with and without ultrasonic speakers.

So, it’s clear that research has yet to come to a definitive conclusion as to whether ultrasonic repellers will work on pests, including bed bugs. However, technology has changed an incredible amount compared to eight years ago, so if you’re tried everything to no avail, it won’t hurt to give a modern ultrasonic bed bug repeller a try.


Do Ultrasonic Pest Repellers Affect Dogs?

Affect, yes. Harm, not at all. Dogs can hear up to 45 kHz, which is more than twice as acute as the average human’s hearing limit. Meanwhile, ultrasonic pest repellers can produce anywhere between 22 kHz and 65 kHz, so a dog can pick up the device’s mid-range output. Although these sounds are foreign to dogs and may cause alarm, they will not damage your pet’s hearing.

 Are Ultrasonic Pest Repellers Harmful To Humans?

Not even in the slightest. The average human’s hearing can pick up sounds of up to 20 kHz, but this figure goes down with age. However, children might be able to pick up the low-pitch frequencies of ultrasonic pest repellers, but it’s not much different from the sound that a TV makes when it turns on. The high-pitch squeaking will not damage you or your child’s hearing at all.

 How Long Does An Ultrasonic Pest Repeller Last?

The average lifespan range of an ultrasonic pest repeller is between three and five years. If you find the device to be effective in your home, consider swapping it out with a fresh device at the three-year mark.


So, do ultrasonic bed bug repellers actually work? You’ll have to look at every case to be certain. Although some studies deny the efficacy of ultrasonic speakers in deterring pests like mice and bed bugs, the limitless anecdotal evidence would tell us otherwise. If you’ve tried every other option to no avail, we highly recommend giving an ultrasonic bed bug repeller a shot.
