Gardigo Marten defence ultrasonic function

Helps protect your house, garage, barn, and attic from martens. Simply plug the device into the socket, and the marten repellent is ready for use. The varying frequencies fill the environment, disturbing the sensitive hearing of the martens. The constant flashing of the LED light is also disruptive. After some time, this can become very uncomfortable for the martens, and they will begin to avoid the area more frequently. Please note: In cluttered attics or with insulation material, sound may not spread as effectively, which may result in a smaller effective range.
