The Vermatik is an ultrasonic and electromagnetic repeller for rats and mice, covering an area of up to 60 sq meters. The ultrasonic and electromagnetic waves are unsettling for rodents, over time they will keep away from the area where the repeller is installed. The repeller also repels insects such as cockroaches and spiders. The frequency of the ultrasonic waves is automatically varied to ensure rats and mice are repelled.
The repellers ultrasonic waves are emitted in a range that will not affect cats and dogs, however it shouldn't be used if you have guinea pigs, mice, hamsters or gerbils as pets.
