The ultrasonic sound waves emitted by the Ultrasonic Rodent Repeller – Dual create stress and intense discomfort in the auditory systems of rodents, making the protected area uninhabitable for them. The Mono, Dual, and Quadro models are manufactured based on German designs and represent a new-generation, high-technology solution for rodent control.
The device is completely harmless to humans and other animals, operating without odor, contamination, or toxic substances. Ultrasonic Rodent Repellers are widely used in modern countries including the United States, Germany, France, Bulgaria, Italy, and Hungary, and in some countries their use is mandatory.
The Ultrasonic Rodent Repeller – Dual emits continuously varying ultrasonic frequencies that cannot be heard by the human ear, effectively driving rats and mice away from the protected area.
If required, additional outputs can be taken from the GFS Dual model to protect blind spots. During the first 10 days of use, an increase in rodent activity may be observed. This indicates that the device is functioning effectively by forcing rodents out of their nesting areas. In some cases, complete evacuation of the area may take 4–5 weeks.
The specified coverage areas represent the maximum effective range under ideal conditions. The device includes test buttons that lower the sound pressure to the human audible range, allowing operational testing.
