What Are Ultrasonic Pest Repellers?
Ultrasonic pest repellers are electronic devices that emit high frequency sounds to negatively affect (e.g. ward off, repel, harm, injure, kill, etc.) all kinds of pests such as rodents and insects.
These electronic devices are often plugged to an electrical outlet. They emit frequencies that can specifically affect their target pests. The frequencies being transmitted by these ultrasonic pest repellers are typically inaudible to humans and highly specific to their targets.

Repellents of different kinds have long been used to ward off pests. History books often cite people of the past (including the present) planting certain shrubs and trees such as citronella and lemongrass to keep mosquitos away.
Plant products such as garlic and chili have also been traditionally used to keep mice and rats away. These are examples of chemical repellents that ward off pests through sensory receptors, specifically their smell and taste.
Other pest repellers that are more commonly used these days include poison and chemical traps. These are also usually generally specific and are used to get rid of various pests, including rats, cockroaches, ants, etc.
In addition, while not as likely, if the pests gain immunity to these poisons that are used to kill them, it may aggravate the situation. This is because you will probably have to increase the poison dosage or use stronger or more severe methods to eliminate them.
Having said that, ultrasonic pest repellers differ from these, as they are electronically powered and affect their sense of hearing.
One way ultrasonic pest repellers stand out from chemical repellents is that they are often targeted at rodents. They also will not affect humans and other animals.
Cockroaches and rodents that lurk within crevices and many other locations are problematic, since it is very difficult to isolate where your problems are. As a result, it is difficult to get rid of them.

However, you can get rid of them easily with ultrasonic pest repellers. This is because you are not required to identify where they are and you may simply turn on the device to drive these pests away.

Hоw does rodent rереllеrѕ work?
While the frequency of the ultrasonic sound irritates and drives away the pests, it is basically undetectable by the human ear. For the pests though, these sounds can cause confusion and convulsions.
They may also suffer from an audiogenic seizure response, which have the following symptoms: non-directional running and/or convulsions. In fact, death is also possible due to cerebral hemorrhage.
Upon exposure, the pests will then usually leave the area to find a better and less threatening environment. This means that they will leave your home and breed, gather food and build nests elsewhere, thereby eliminating their presence in your home.
These are a popular alternative to traps and poison because their impact on humans is low and it is considered to be a more humane form of pest control.
Can You Use This For Your Car?
If you live in a wooded area with more trees and greenery, you may face problems with chipmunks, mice and rats that are trying to nest inside the crevices of your car.
For these situations, there are ultrasonic pest repellers that can be placed under your hood to keep them out.
Mode of Action
The use of sound to repel mice and rats depend on their physiology. Compared to humans, rodents have a much higher range when it comes to hearing sounds. Rodents actually have a hearing range comparable to that of bats.
Being ultrasonic, these electronic pest repellers often use frequencies higher than 2,000 Hz, significantly higher than what humans can call audible.
Just like how humans feel discomfort when exposed to high-pitched sounds, these ultrasonic frequencies make pests feel discomfort. It makes them seek out environments that are more tolerable.
In fact, people who are sensitive to high-pitched sounds can sometimes hear the ultrasonic pest repellers as a mild whining or white noise.
If left operating indefinitely, these repellents will be able to rid your home of pests and can potentially help prevent pests from coming into your home in the first place.
Dо Thеѕе Ultrаѕоniс Pest Rереllеntѕ Rеаllу Work?
As of now, the effectiveness of ultrasonic pest repellers are mixed. Most products do not claim 100% effectiveness on any pest.
But thankfully, most studies found a reduction of all pests.
In a test performed by Kansas State University in 2002, they found that the effectiveness varied between different pests after testing the device on various ones. In that study, the devices worked well at repelling crickets but did not work as well on cockroaches.
Ants and spiders were unaffected by the device. Ultimately, the pests that were initially affected by the noise soon became used to the sounds and ended up returning after a period of time.
The study also found that signal strength would diminish as it went further and would be blocked by walls and furniture. Conversely, the test showed promising results in a study by Victor Pest Control.
The product managed to successfully repel rodents from 13 of the 17 sites that were tested and the food consumption in the treated areas was lowered by 67%. Rodent activities were generally stopped in an average of six days.
In addition to the effectiveness, there were some safety concerns when it came to these devices.
Several users have noticed that these ultrasonic waves can weaken the clarity of telephone conversations, interfere with burglar alarm systems and cause muting in users’ hearing aids.
Another side effect is that the ultrasonic sounds can distress your pet rabbits and rodents, such as guinea pigs and hamsters. Other pets like dogs and cats can hear the sounds since they are within their ultrasonic range perceptions, but they do not seem to be bothered by the noise.
However, all of these side effects may vary from device to device and you may need to try your specific model before you know if these are concerns.
To increase the effectiveness of ultrasonic pest repellents, you may consider using traps concurrently. When the ultrasonic waves cause havoc amongst your pests, they are more likely to scurry into your traps.
This way, you will get rid of them by both driving them away and killing some of them. However, if you have concerns about the ethicality or safety of using traps, this may not be your best choice.
How to Choose the Best Ultrasonic Pest Repeller
As ultrasonic pest repellers are relatively new, there are quite a few options available. If you are looking for a new ultrasonic pest repeller, there are several things you should consider before selecting one.
- Repeller’s Lifespan
Based on how much you pay, you may get a pest repeller that could last longer. Disposable pest repellers will definitely last for less time than expensive models, which can sometimes last for years.
The disposable models will cost less but will also require frequent replacements, since they are generally more cheaply made.
Knowing how long you will need an ultrasonic pest repeller and how much money you are willing to spend on it can determine which kind of repeller you should purchase.
These ultrasonic pest repellers can vary in prices. The price can depend on the brand and the number of different pests it can repel. Expectedly, the more pests a device can repel, the more expensive it generally is.
Another factor that affects price is whether the device is plug-in or corded. Corded repellers are generally more expensive.
- Plug-in VS Corded Repellers
Plug-in repellers are mostly cheaper and are usually sold in packs of 4 to 5 repellers. These repellers commonly have less reach and require you to purchase more units to cover your entire house.
This is also due to the fact that sound does not travel through furniture and walls. As a result, you need to buy more units to make sure that every area is exposed to the ultrasonic waves to ensure effective pest elimination.
Corded repellers usually have a longer and wider range, but this reach comes with a higher price tag as well. These systems work much better and can normally cover about 5000 square feet. They do a good job in covering places like attic or basement areas with just a single unit.
Either option you choose, it comes down to the space that you are trying to cover. Plug-in repellers may also be better if you have pets. This is because you can choose which areas you would like to cover instead of a corded repeller that covers an entire area.
- What Kind of Pest Situation Are You Facing?
If you have widespread pest issues, consider buying more repellers to fill multiple rooms. If you have pests in one area in particular, consider a long-lasting model for that one space.
If you only have pests during a particular time or season, disposable, low-cost options will suit your needs better.
- Repeller’s Strength and Range
Every device has a varying level of ultrasonic waves. They can also vary in frequencies. The key is to find a suitable ultrasonic repeller that has an appropriate frequency. This frequency shouldn’t affect your beloved pets but will surely repel your pests.
Devices that have higher frequencies will effectively drive other pests away from your home without harming the pets.
When choosing these devices, you may want to consider the amount of noise it produces. While a human generally cannot hear the high-pitched noises, they might hear other noises that the device may produce.
For example, some devices generate clicking noises while some produce white noise. Children may also be more sensitive to these devices since their younger ears may be able to hear noises within these higher frequencies.
- Are They Safe for Pets?
You might wonder if these devices also affect your pets, since they affect pests who are also animals. Testing has found that dogs and cats are not generally affected by these sounds.
Dogs and cats are usually only affected by these sounds if they are extremely loud, as high frequencies do not really cause discomfort to animals, even if they can hear them.
Some manufacturers have tested these devices on dogs and they either responded by moving away from the source of the sound, moved towards it in curiosity, or remained indifferent to the sounds and stayed still.
While they have been proven to be safe for your cats and dogs, you should still exercise caution and observe your pets while you use them.
If you find that they are exemplifying signs of distress or discomfort, stop using them. Or use them only in areas where your dog does not frequent. You may also ask your vet if you have any questions.
Smaller, rodent-sized pets like hamsters, guinea pigs and even rabbits can be adversely affected by ultrasonic pest repellents. Tests have found that they show signs of distress and discomfort when exposed to the ultrasounds.
If you have any rodent-like pets, you might consider avoiding the use of ultrasonic pest repellers. Conversely, some ultrasonic pest repellers have frequencies that may be way higher than the ranges that can affect your pets but will also be able to affect the pests.
With close research, you may be able to find a compromise that will suit your needs without harming or distressing your pets.
