How PESTFree Works

The PESTFree motion sensor detects movement in the protected area. The sensor triggers a 10 second ultrasonic burst, which will repeat until the intruder leaves the protected area. A red light behind the lens indicates that the CatFree has been triggered.

Why PESTFree Works

Unlike many pest deterrents that operate continuosly, PESTFree waits for the animal to enter the protected area.

  • Internal sensor detects the crossing of a warm body (e.g. a cat, dog, rabbit or possum).
  • A powerful ultrasonic sound burst startles the animal.
  • The animal learns that he or she is causing the unpleasant occurence to happen every time the cat goes into the protected area and therefore stays away.
  • The animal avoids the protected area in the future.


PESTFree is made of weather-resistant materials and comes with a 2 year manufacturer warranty.

We have found this product to be good as it has stopped the cats from coming over and going to the toilet in our garden
The delivery was not left at our door and was difficult to find who to pick it up from

I think it would be neat if the unit gave a wee beep so I know there has actually been a cat or dog in the area. I have seen one cat in front of it today but the only one since I've owned it, like a month. The cat could have been deff but it dropped down and slowly sneaked away, I'm hoping the unit got it big time.
