Upgraded Ultrasonic Rodent Repellent for Car Engines 2 Packs Plug-in & Battery Operated Rat Repellent for Car Under Hood Mouse Deterrent Keep Mice Rats from Automobile Attic Garage Ba

• Keep Rodents Away from Vehicle Wiring: Help keep mice, rats, squirrels, and chipmunks away from your car or truck engine compartment before nesting and chewing around wiring harnesses, hoses, and insulation can lead to costly damage. This under hood rodent repeller works as a practical mouse deterrent for car engine compartments and truck engine bays, helping discourage rodent activity around vulnerable components when vehicles sit overnight or for several days
• Automatic Standby While Driving: Drive without having to switch the device on and off every time you use your vehicle. Built-in vibration sensing detects engine operation and automatically places the vehicle rodent deterrent into standby mode while driving. Once the vehicle is parked and vibration stops, deterrence automatically resumes after approximately 120 seconds, so the unit can return to operation without manual restarting
• Dual-Action Under-Hood Deterrence: Help make the engine compartment less inviting to rodents with 1836 kHz high-frequency sound and flashing lights working together. This ultrasonic rodent repeller combines sound and visual stimulation around the engine bay to help discourage mice, rats, squirrels, chipmunks, and other small rodents from lingering near vehicle wiring and other under-hood areas
• 3 Power Options for Flexible Installation: Power this car rodent repeller with 4 AA batteries (not included) for cordless placement, a 512V USB power source for convenient external power, or connect it directly to a 12V vehicle battery for a more permanent under-hood setup. Three flexible power options make it easier to choose the setup that fits your car, truck, parking situation, and installation preference without relying on a single power method
• 2-Pack for Practical Placement: This 4 pack rodent repeller set lets you use multiple units under the hood of your vehicles and place additional units in garages, attics, basements, sheds, or storage areas where signs of rodent activity may appear. Included zip ties make mounting simple; install each unit in a dry, sheltered location away from direct water exposure and moving engine components
• Wide Temperature Range Operation: Functions reliably in demanding environments with an operating temperature range of -25C to +65C, ensuring consistent performance in both cold winter conditions and hot summer temperatures. The device features ultra-low power consumption of less than 0.1W to prevent battery drain during extended use

• What animals is this under-hood repeller designed to deter?

  It is designed to help discourage common rodents such as mice, rats, squirrels and chipmunks from exploring parked vehicles, engine bays and other suitable sheltered areas.

• Does the device work while I am driving?

  The built-in vibration sensing system detects vehicle movement and places the device into standby while driving. After the vehicle stops, it waits about 120 seconds before automatically reactivating the deterrent cycle.

• How does the rodent deterrent work?

  The device combines 18–36 kHz variable ultrasonic output with white flashing lights to provide two deterrent responses around the engine bay while the vehicle is parked.

• What power options can I use?

  Choose from three power options: 4×AA batteries, USB power with 5–12V input, or a 12V direct connection. AA batteries are not included.

• Where can I install the device?

  It can be used in cars, SUVs, trucks and RVs, as well as garages, attics, warehouses and indoor storage areas. For under-hood use, secure it in a clear location away from hot or moving engine components.
