What Sound Frequency Repels Rodents?

An ultrasonic rodent repellent is an ultrasonic device that emits high-frequency sound waves to deter rodent infestations.

The high-pitched sound emitted from this ultrasonic rodent device causes auditory stress in rats and other animals.

It is a hand-sized device that is commercially available in two forms.

One form is battery-operated, and the other type is plug and play, which you have to plug into a power source directly.

The battery-operated ultrasonic repellents are portable as you can use them outdoors.

On the contrary, plug-type ultrasonic rodent devices are best to use indoors since they can be turned on all the time while consuming very low energy.

The high-frequency noise of these ultrasonic sound repellents is a major driving force to counter a rodent problem.

Generally, the ultrasonic waves are emitted continuously while changing the intensity.

How Does Ultrasonic Rodent Deterrent Work?

The ultrasonic rodent repellent works by utilizing the sound energy of ultrasonic frequency sound waves to deter rodents.

The sound frequencies of ultrasonic rodent repellents cause immense irritation to these nocturnal creatures, and thus, they are forced to leave the premises.

You only have to plug this device into a power outlet, and it will start emitting ultrasonic sounds continuously while changing the intensity levels.

As per manufacturers, the intensity levels fluctuate so that the pesky pests do not get used to only one range of ultrasound. The device takes a meager amount of electricity to operate.

Therefore, to determine and expect results per your requirement, you will have to keep the device operational, and within a matter of a few days, you will see a significant decrease in rodent activity.

These ultrasonic rodent devices work on the deterrence principle of keeping mice, a rat, and other rodents away from your property using high frequencies of sound.

What Attracts Rats to Your House?

The rats, mice, and other rodents are attracted to your house majorly in search of food.

Open garbage cans and pet food are also great sources of food for these rats and mice.

A dirty living environment and unclean kitchenware are also major reasons that attract a rat to your house.

The openings in a wall outlet are more than enough for a rat to infiltrate your property.

Uncovered garbage cans and feces of your pets like cats can attract a rat in a blink of an eye because the sense of smell of rats is enormous.

Why Are Rats Considered Harmful?

Rats are one of the most harmful rodent creatures on this planet.

Rats play a significant part in food contamination. According to the research-based analysis of the World Health Organization, rats contaminate food annually that can feed 200 million people.

Furthermore, the list of diseases caused by rats is also very long.

Some of these diseases which have caused devastation to humans are the plague, the hantavirus, Tularemia, and Salmonella.

Usually, a rat transmits these deadly diseases via contaminated food or by biting.

As per statistics, more than 45,000 people are bitten every year by rats.

Therefore, we cannot undermine the impact of this rodent problem.

What sounds do mice hate?

Mice have very sensitive ears and can hear ultrasound of high-intensity wavelengths.

They hate the sound of ultrasonic rodent repellent devices, which is usually in the range of 32 kHz to 62 kHz.

The sound of these ultrasonic rodent repellers may it extremely irritating for these filthy creatures.

Resultantly, they will vacate the premises immediately where this ultrasound instrument is installed.

Another important reason mice hate the sound of an ultrasonic rodent repellent device is that it continuously changes the intensity.

Thus, these creatures are irritated up to a maximum extent.

What is the Intensity of Ultrasonic Sound Waves?

The noise intensity of these ultrasonic sounds ranges from 32 kHz to 62 kHz. However, it may go up to 100 kHz for some devices.

The intensity level of sounds of this ultrasonic rodent repeller has been standardized by keeping in consideration the hearing range of humans.

Rodents can hear the noise of high-intensity, while human hearing cannot exceed 20 kHz. Therefore, these ultrasonic rodent repellers are safe to use as per Environment Protection Agency.

The range of these ultrasonic devices is up to 200 square feet. However, these sounds cannot cross the walls and will bounce off them.

On the other hand, it can ward off rodent pets, and thus, you should not use these instruments if you have any rodents as a pet.

What Frequency Do Rodents Not Like?

Rodents do not like any noise greater than 30 kHz. Sound greater than this intensity will irritate these pesky creatures.

These high-intensity waves cause irritation because rodents have sensate ears.

Does High Frequency Repel Rodents?

Yes, it repels rodents effectively.
The high intensity will cause immense stress and irritation to these creatures. Ultimately, the only way left for them will be to vacate the premises.
