Chewed wiring under the hood is what you want to avoid, and this unit discourages squirrels, rats, mice and martens from the engine bay without killing or injuring them. It runs on the vehicle's own 12V power with nothing to recharge. Switch the engine off before connecting, and have a mechanic fit it if you are unsure.

This ultrasonic mouse repeller plugs two cables into the vehicle's electrical circuit (12V) and sweeps 12-45 kHz vibration through the engine bay. Rats and mice get the same treatment, so it serves as a rat repellent for car use and a mouse deterrent for car engines. At 4.58 ounces this ultrasonic rodent repeller tucks under the hood, and as an ultrasonic pest repeller it also covers moles and chipmunks.
