Can Dogs Hear Ultrasonic Pest Repellers?

Many people don’t know that dogs have an incredible hearing range. Dogs can hear anywhere from 67 to 45,000 hertz. In addition, ultrasonic pest devices can release sounds up to 65,000 Hz. This means that some dogs can listen to them if they have a stable hearing range.

What Frequency Is Harmful To A Dog’s Ear?

Frequencies starting at 25,000 Hz can irritate your dog’s ears. However, if the frequency goes higher than that, it can cause irreversible harm. As you may know, dogs have better hearing abilities compared to humans, so if you can withstand hearing the sound, so can your dog. However, it is good to keep in mind that loud sounds can irritate or scare your pet.

How Can I Know If My Dog Hears An Ultrasonic Pest Repeller?

As you can see, there is a good chance that your dog can hear an ultrasonic pest repeller. Dogs are sensitive to different sounds (it does not matter if they are low or high pitched). Furthermore, they tend to show signs that can tell you if they hear a sound or find a sound annoying. Those signs can be portrayed with body language or behavior.

Although most ultrasonic pest repeller brands claim that they sell pet-friendly devices, you should avoid making your pet uncomfortable, distressed, or scared. Instead, the sellers of these devices recommend placing them in strategic places where sound can travel from one place to another around your house.

How Do Ultrasonic Pest Repellers Work?

When ultrasonic pest repellers are plugged in, they emanate high-frequency sounds that humans cannot hear. But some organisms, such as mosquitoes, bugs, fleas, cockroaches, spiders, rodents, and other animals, can hear them because they have a higher auditory ability. Consequently, these devices repel those animals. There are many people who use these pest repellers when there are pests throughout their homes.

The time can vary according to your situation. For instance, if your house infestation stops within two to three months, it would not be necessary to have one that lasts longer. On the other hand, some consumers might want the device to last longer, and two to three months would not be enough.
