The device uses variable-frequency ultrasound from 18–36 kHz, designed to repel martens, mice, rats and other rodents.
Two flashing LED diodes support the repellent effect and indicate that the repeller is operating.
The repeller can be powered by a car battery, four AA batteries or via a USB cable. Thanks to the mounting brackets, it can be easily secured in the engine compartment or on a wall.
The GreenBlue ultrasonic repeller is a practical solution for protecting the engine compartment and other areas from damage caused by rodents and martens. The device emits a variable-frequency ultrasonic signal designed to repel pests without killing them.
Its compact design allows for easy installation under a car bonnet, on a garage wall, in a gazebo or in other suitable areas. The flashing LED diodes enhance the deterrent effect and make it easier to check that the device is operating.
