Ultrasonic scavengers

What are ultrasonic repellents against pests?

The idea behind ultrasonic scavengers is that you make the environment as unpleasant as possible for unwanted guests. Foxes coming to eat your chickens, or cats doing their business in your vegetable garden... With the help of an ultrasonic repellent, you can easily stop this and make sure these intruders don't come back. 

Ultrasonic sounds are very high pitched sound tones. They are often inaudible to the human ear, unless you have really good hearing. Then you might just be able to hear the lowest ultrasonic sounds. The frequency range of the human ear decreases with age. So it is quite possible that children can hear the beeping of an ultrasonic repellent and adults cannot. 

You don't want to stay in a place where you hear an annoying beeping all the time. And that's how animals think too. An ultrasonic repellent produces high-pitched, beeping sounds that make foxes, martens, cats or even birds perceive your garden as an unpleasant place. 

It is important to buy the right ultrasonic repellent for the type of unwanted visitor in your garden or on your property. This is because the various devices are tailored to the animal's hearing. A cat has a different hearing range than a marten, and that of a bird is even different. 

The ultrasonic repellents change sound patterns to avoid habituating the unwanted guests to the sound. This ensures that the device remains effective.
