Keep mice and other rodents away from the car or home with this ultrasonic deterrent. Using flashing lights and ultrasonic frequencies that are nearly imperceptible to the human ear, this ultrasonic mouse repellent for cars can be used in a variety of indoor locations. Place it under the hood of the car, in closets, or in sheds and garages. It provides coverage for up to 484 square feet, and the frequencies change to help prevent rodents from growing accustomed to the sound. This repeller can be powered three different ways, by adding 4 Aa batteries (not included), plugging it into a Usb port (only when used indoors, Usb wall adapter is not included), or by connecting it to the car battery. Plus, the device features a vibration sensor that only allows the unit to operate when the car is stationary. It includes 4 zip ties to easily keep the repeller secure.
