Ultrasonic Pest Repeller: Do They Really Work?

An Ultrasonic pest repeller is a great way to deter insects and animals with sound waves. Though sounds have been used for ages to repel animals over time, technology has improved a lot. These pest repeller devices are products of the latest technology with many contributions for repelling pests.

This guide covers all aspects of ultrasonic pest repeller or mosquito repeller with the basics, working principles, and consequences on pets. Above all, the tips given at the end of the article can increase the device's productivity and help get rid of insects maximally.  

What is an Ultrasonic Pest Repeller?

Ultrasonic pest repeller is a device that emits high-frequency sound waves to deter or kill insects like mosquitos, cockroaches, and other pests. The sound produced by this device is too high to be heard by human ears but can be detected by some types of pests. When annoying pests or mosquitoes get these vibrations, they are hampered and get away from that site.

Normally, ultrasonic pest repellers are handy with no extensive installation or wiring. All you need is to plug in the socket and let it deter nasty pests. At the same time, other devices have smart technology that doesn't require even a plug or socket. They are battery-operated or connected with Bluetooth or WiFi to enjoy a mosquito-free gathering in lawns or outdoors.

Ultrasonic pest repellers specifically target insects and animals such as:

  • Spiders
  • Cockroaches
  • Mosquitos
  • Bed bugs
  • Flies
  • Fleas and ticks
  • Rodents

How Does Ultrasonic Pest Repeller Work?

The ultrasonic pest repellers work on the principle of emitting short wavelengths and high-frequency sound waves to deter mosquitos and other pests. Different species of pets don’t like the sound and vibrations emitted by the device. Rather than put up with the annoying noises from the repeller, the pests and insects flee your home and garden and seek refuge in areas not covered by high-frequency sounds.  

A big Concern! Many homeowners get worried that the sounds of ultrasonic pest repellers can be damaging to their family and their pets. It is worth wondering as living in a disturbing or threatening space just to kill mosquitos is not a wise decision.

But, the good news is, ultrasonic sounds are beyond the hearing capacity of humans. Typically, a human ear can detect sounds ranging from 20 Hz to 20 kHz, while the frequency of ultrasonic pest repeller is higher than this range. So, you can feel confident about getting a device and keeping mosquitos at bay with its superpower.

Is Ultrasonic Pest Repeller Safe for Pets?

Similarly, pets are considered a part of the family and live in the same house; thus, their health must be valued, and you should not use anything damaging.

Some studies claim that pests are unaffected by ultrasonic pest repellers. Most ultrasonic pest repellers emit sounds above 20kHz, and the level of frequency your pet hears depends on the type of animal. For example, dogs, cats, rabbits, birds, and hamsters can hear different sounds and react differently.


Dogs can pick up sounds up to 40 kHz. Normally, they are least affected by the ultrasonic waves because ultrasonic devices are used for dog training, and they can hear them daily. So, generally, they don’t react to those sounds. On the other hand, some nervous dogs will be anxious or curious about the device.

Keep in mind, their reaction is not significant, and the device does not harm dogs. However, they may get stressed if spending a lot of time in the room where the ultrasonic pest repeller is turned on.


 Cats can hear sounds up to 60 kHz, so there is the possibility that your pet notices the vibrations. But there is nothing to worry about as it is not harmful most of the time.

Is Ultrasonic Pest Repeller Worth the Money?

Due to multiple benefits, investing in ultrasonic pest repellers is absolutely worth the money. The mosquitoes are a constant threat, and their population increases in no time. Above all, they carry infections of various diseases such as Malaria, Zika virus, West Nile virus, and many other diseases that may spread like epidemics.

Similarly, these devices do not contain chemicals or harmful gases and are safe around kids. Plus, there is no release of toxic substances in the surroundings, and the air remains purely breathable.

So, instead of bearing itchy bites and buzzing sounds of mosquitos, it is highly recommended to invest in ultrasonic pest repellers. They are not costly, and good ultrasonic devices cost a few hundred dollars.  

Expert Tips to Use Ultrasonic Pest Repeller

Here are some expert’s tips to help use ultrasonic pest repellers in a better way:

  • First, use the mosquito repeller in areas with a high population. For instance, if there are countless insects in a room or garage, use the device over there. In a room with mostly hard surfaces like a kitchen, ultrasound will bounce around, giving coverage to more space.
  • You can also use these devices in storage areas or pantries where mosquitoes hover over the food or stored items, resulting in contamination.
  • The ideal placement would be one that allows the sound waves to cross in front of an entranceway so, use it at the right place.
  • Ultrasonic sounds are more like light that cannot penetrate solid surfaces like walls, floors, ceilings, or travel around corners. Therefore, there will be a need for more than one device to be used simultaneously in different sections of the house.
  • Using smart ultrasonic pest repellers allows getting rid of mosquitoes outdoors in the garden or at a picnic spot. So, keep the device with you to be protected from insects whenever you plan to go out.
