Ultrasonic Pest Repellers
Ultrasonic pest repellers use high-frequency sound waves designed to discourage pests from occupying an area. These sound frequencies are typically unpleasant to pests such as rodents and some insects, while remaining unobtrusive in everyday environments.
Ultrasonic repellers are commonly used for ongoing, preventative pest control in homes, roof spaces, garages, and commercial settings. They operate continuously once powered and require minimal maintenance, making them a convenient option for long-term pest deterrence.

Customer Reviews About Audible & Ultrasonic Pest Repellers
Our fig tree was getting attacked by birds after one day the figs were saved. The rabbit and the rats also moved home. Should be called the eradicator
Appears to be working ok
So far so good, it's only been a few weeks but no scuttling in the walls or roof. Ask me again after 12 months use.
Really good! We’re on a dairy farm and last year had over 400 ducks on the effluent pond and surrounding area. This year, with using the cannon, the ducks take off straight away once it starts going and we have on average 40 ducks hanging around. Very happy 😊
I’m impressed with this product in one week time no more rat noises from the ceiling and food poison not touched so they run far, very happy with this purchase. Had 2 cats and 2 dogs they have no issues since this product is on either. Good investment.
My new Pestrol Rodent Free device is doing its job. My upstairs has not seen hair or antenna of a pest since its arrival. A second is definitely on the agenda as soon as the budget permits.
This is a great product. We had a problem with neighbours cats visiting and causing havoc in our garden. Got two of these, one for the front and inside the garden. So far no cats for the last two weeks.
Does what it says on the pack! As I stood in the shed trying to figure out where to put it, the resident rat made a run for it and didn't come back. I only got 4 months battery life with a high quality lithium battery though
