Rodent Repellent for Car Engines Ultrasonic, Indoor and Outdoor. Power by Car Battery or Wirelessly. Rat Squirrel Mouse Deterrent Mice Repellent for Cars RV. Rodent Repeller to Keep Rodents Out of Car

PROTECT YOUR CAR FROM RODENT DAMAGE. This easy to install under hood rodent repeller prevents rodents (rats, mice, squirrels, martens, chipmunks etc) and other pests from making nests in your car and chewing through the wires. It does this by emitting a combination of ultrasound and strobe lights which rodents hate. 4 reusable plastic ties are included so you can easily attach the device to your engine.
WON’T DRAIN CAR BATTERY. This electronic mouse repellent device is powered by your car battery via the included charging cable. If your vehicle battery drops below 9.2V, the device will automatically turn off to ensure your battery won’t die. Once the battery charge exceeds 9.2V again, the device will automatically turn back on.
USE ANYWHERE, NOT JUST YOUR CAR. Since the repeller can also be powered wirelessly via 3 AA rechargeable batteries (included) you can place it anywhere you want to deter rodents, e.g as a squirrel repellent for attic. When the batteries die you can recharge them with the included USB cable, or simply leave it plugged in to run it 24/7 without it ever dying. You also have the option of turning off the strobe lights, so you can use it at home in rooms where the lights would be annoying to see.
SAFE FOR PETS. INAUDIBLE TO HUMANS. Ultrasound is completely inaudible to humans meaning no annoying noise to bother you. Dogs and cats can hear it, but the volume is too low to cause them any bother at all. The best ultrasonic rodent repeller should be usable for all.
