1) What is ultrasonic sound?
The outdoor garden units have a PIR (Passive Infra Red) sensor installed. These are activated by the movement of body heat, which in turn triggers a 5 second ultrasonic burst – a noise that the pest will find unpleasant, which will repeat until the animal leaves the protected area. This noise is inaudible to humans and harmless to all species.
2) Why does it only affect the targeted pest?
Each type of unit is set at a different ultrasonic sound level, and as certain animals have different levels of hearing, this ultrasonic sound can be tailored to the species of pest the unit aims to deter.
3) How long do Ultrasonic repellent take to work?
As Ultrasonic deterrents are humane, they do not work instantly, It should take about 2 to 4 weeks before the full deterrent effect is achieved.
This varying degree of effect time is caused by the animals attitudes! Although they all find the sound irritating, some may be more inquisitive and investigate where the sound is coming from. Meanwhile, some cats are stubborn.
5) Ultrasonic animal repeller work in all weathers!
Ultrasonic animal repeller are also superior because they work in all weather conditions, and can be used over long periods to prevent new pests entering your property.
