The Big Cheese Battery Powered Ultrasonic Mouse Repellent

Ultrasonic protection for out of reach areas providing continuous protection of areas without mains electricity that are vulnerable to infestation by mice. The welfare-friendly deterrent produces sound waves that are inaudible to humans and non-rodent pets, including cats and dogs, but are disturbing to mice. Use one Battery Powered Mouse Repellent unit for each treatment area. For larger or irregular shaped treatment areas more than one unit may be required. Features a low battery indicator and uses 3 x AA batteries (not included)
