What Are Ultrasonic Pest Repellers?

Simply put, ultrasonic pest repellers are devices that can injure or kill pests by releasing high-frequency sounds. These high-pitched sounds or vibrations interfere with the pests so much that it drives them away or kills them.

Are Ultrasonic Pest Repellers Effective?

To this day, there is no definitive answer to ultrasonic pest repeller effectiveness with disputes from testing labs and the US Federal Trade Commission (FTC). Many individuals also question their effectiveness since these devices are not yet backed up by the US Environmental Protection Agency (EPA), an agency concerned with human and environmental protection.

However, the fact that these devices are still in the market means they help in controlling pests, and buyers purchase them for a reason. Many online buyers can attest to these devices’ effectiveness when they leave 5-star reviews on the shops’ sites they bought from.

There is still more to learn about these devices, and you can read more about how ultrasonic pest repellers work on different sources online.

How Does It Work?

Ultrasonic pest repellers cause a physiological response in terms of s seizures in pests. This is caused by short wavelength and high-frequency sounds that go at an average of 65,000 Hz that can cause cerebral hemorrhage after convulsions. This high range of sound is inaudible to the human ear that can only hear up to 20,000 Hz but can be heard by pests.

With the repeller, the pests’ cycle is disrupted – they won’t be able to gather food, create their den, or continue breeding. They will also fail to communicate with the other pests. Taking these essential survival needs away will make the pests run out of the home, away from the sound.

How to Use Them?

Utilizing sound to deter pests has already started since 1948, and devices have only been developed and improved since then.

The device just needs to be plugged into an electric outlet. Some are even battery-operated. This is so it can be used in an outside setting such as the fields or gardens. With the LED light indicating that it’s on, the repeller will start to emit sounds that can’t be heard by human ears but are troublesome to pests.

What Pests Can Ultrasonic Pest Repellers Deal With?

There are many pests these devices claim to deter, such as:

Rats and Mice

Rats and mice can carry many diseases while they linger on the countertops and other sections. Hantavirus, salmonella, and leptospirosis are only some of them. Simply touching this pest’s droppings, urine, or breeding site is dangerous.


Spiders are not known for transmitting infectious diseases, but some carry toxic venoms that cause neurotoxicity and systemic illnesses.


This pest is known for bringing many diseases with them – diarrhea, cholera, even leprosy, and typhoid fever – the list goes on. With their many numbers and fast-breeding, cockroaches have been man’s great foe in combating many illnesses.


Ants are often a symbol of perseverance, but they can also carry bacteria and fungi. Especially if they manage to get to your food, ants can transmit diseases like salmonella, strep, and E.coli.


At the same level as cockroaches, flies are not only irritating but also dangerous. As they love to touch the dirtiest of places, flies can cause anthrax, cholera, tuberculosis, and many other diseases and infections. Flies love to disrupt your life especially when you are chilling on your composite deck from untradeck.


Dengue and malaria are diseases that are not easy to deal with. Zika virus, Yellow Fever, West Nile virus, and other vicious illnesses are carried by these small killers as well.

Fleas and Ticks

Typhus and plague can be transmitted by fleas, aside from the Bartonella infection. These external parasites can move from your pets and cling to you.

Bed Bugs

Although bed bugs are not known spreaders of diseases, they still cause skin irritation and difficulty sleeping.
