While all the above methods can help secure your property, you can’t control your neighbours, of which, some will inevitably attract foxes. This is why it is useful to first try ultrasonic devices, before resorting to more expensive solutions.
Ultrasonic repellers work by emitting ultrasound, which is inaudible to humans, but unpleasant to foxes, causing them to leave the area. Ultrasound is preferred as it functions as a permanent deterrent to foxes and causes no inconvenience to humans.
Some models are fitted with a sensor and will only activate in the presence of a fox. This ensures that a fox will associate its presence with the noise. Our devices also emit at random-timing intervals in a wide range of frequencies, which ensures the fox doesn’t get used to the noise.
