Under Hood Rodent Repellent for Cars, 4 Pack Ultrasonic Strobe Deterrent

Product DescriptionHelp discourage unwanted rodent activity around your vehicles and covered storage areas with this 4-pack under-hood rodent repellent system.Mice, rats, and squirrels may enter parked vehicles in search of warmth, shelter, or nesting space. Once inside an engine compartment, they may leave nesting material, droppings, or chew around wires and other components. This electronic deterrent is designed to make these areas less comfortable for rodents without requiring bait, glue boards, or daily spraying.Multi-Sensory Deterrent SystemEach unit combines three programmed outputs:18–36kHz variable-frequency ultrasoundFlashing white LED strobe lightsIntermittent audible soundThe changing signals help create an unpredictable environment around the installation area. Performance may vary depending on rodent activity, vehicle design, competing food sources, nesting material, and product placement.Automatic Vehicle OperationThe built-in vibration sensor is designed for parked-vehicle use. When the device detects sustained vehicle vibration, it enters standby mode. After the vehicle is parked and vibration stops, the unit automatically resumes its programmed operating cycle.A red indicator shows the active working cycle, while a green indicator flashes during standby. The white LED lights operate in a programmed flashing pattern during the active cycle.Three Power Supply MethodsChoose the most suitable power source for each location:4 AA BatteriesSuitable for quick installation without wiring.DC 5–12V Vehicle PowerConnect using the included DC cable for long-term under-hood use.USB 5V PowerUse the included USB cable with a compatible USB power source in garages, attics, warehouses, sheds, or other covered locations.AA batteries and USB wall adapters are not included.Designed for Multiple LocationsThe 4-pack can be divided between:CarsPickup trucksRVsGaragesAtticsShedsWarehousesBarnsCovered storage areasFor a standard vehicle engine compartment, begin with one properly positioned device. Larger, divided, or open spaces may require additional units.Installation InstructionsTurn off the vehicle and allow the engine compartment to cool.Remove visible nesting material, food residue, droppings, and other rodent attractants.Use the included zip ties to secure the device to a stable location.Keep the device away from the engine surface, exhaust components, radiators, belts, fans, and moving parts.Make sure the device and cables cannot become loose while driving.Select a suitable power supply and turn the unit on.Check the indicator lights regularly to confirm normal operation.Do not mount the device directly on a hot engine component. Do not expose it to rain, high-pressure washing, or direct water spray.SpecificationsQuantity: 4 UnitsUltrasonic Frequency: 18–36kHzPower Input: DC 5–12VWorking Current: 14 ± 2mAPower Consumption: Less Than 0.1WPower Options: 4 AA Batteries, DC Vehicle Power, or USB PowerOperating Temperature: -25°C to 65°CInstallation: Zip-Tie MountingWater Resistance: Not WaterproofPackage Includes4 Rodent Repellent DevicesUSB Power CablesDC 5–12V Vehicle Connection CablesInstallation Zip TiesUser InstructionsAA batteries and USB power adapters are not included.Important Use ExpectationsThis product is designed as a gradual deterrent rather than an instant rodent removal device. For better results, remove existing nests, clean remaining odors, eliminate nearby food sources, and operate the units consistently.Depending on the level of rodent activity and installation conditions, noticeable changes may require approximately 3–4 weeks. Reposition the device or add another unit if activity continues.Customer Questions and AnswersQ1: Does it automatically turn off while the vehicle is moving?A: Yes. The built-in vibration sensor detects vehicle movement and places the device into standby mode while driving. After the vehicle is parked and vibration stops, the device automatically resumes operation.Q2: What ultrasonic frequency does it use?A: The device operates with a variable ultrasonic frequency of 18–36kHz. The changing frequency is combined with flashing LED lights and intermittent sound.Q3: What power options are available?A: Each device can be powered by 4 AA batteries, the included DC 5–12V vehicle connection cable, or the included USB cable. AA batteries and USB wall adapters are not included.Q4: Are the USB and vehicle power cables included?A: Yes. USB power cables and DC 5–12V vehicle connection cables are included with the package.Q5: Can I install it directly on the engine?A: No. Do not install the device directly on the engine or other high-temperature components. Secure it to a stable location away from exhaust parts, radiators, belts, fans, and moving components.Q6: Is the device waterproof?A: No. The device is not waterproof. Keep it away from direct rain, engine washing, pressure washing, and other sources of water.Q7: Can it be used in a garage or attic?A: Yes. In addition to vehicle engine compartments, it can be used in garages, attics, sheds, warehouses, barns, RVs, and other dry, covered spaces with a suitable power source.Q8: Does it work on mice, rats, and squirrels?A: It is designed to help discourage mice, rats, squirrels, and similar rodents. Results can vary depending on the animal, activity level, food sources, nesting conditions, placement, and surrounding environment.Q9: How many devices should I use in one car?A: One properly positioned device is generally suitable for a standard engine compartment. Larger vehicles, divided spaces, or areas with heavy rodent activity may benefit from an additional unit.Q10: How long does it take to see results?A: Results are gradual and may require approximately 3–4 weeks of consistent use. Remove nests, food residue, droppings, and remaining odors before installation to improve the surrounding conditions.Q11: Is the strobe light adjustable?A: No. The white LED strobe follows a programmed flashing pattern during the active operating cycle and does not require manual adjustment.Q12: Can people hear the device?A: The ultrasonic output is above the normal hearing range of most adults, but the device also produces an intermittent audible sound. Some people or sensitive animals may notice the sound, so avoid placing it near bedrooms or pet resting areas.Q13: Will it drain the vehicle battery?A: The device uses less than 0.1W during operation. Actual battery impact depends on the vehicle, battery condition, connection method, and how long the vehicle remains parked. Check the vehicle battery regularly during extended storage.Q14: How long will AA batteries last?A: Battery life varies according to battery quality, temperature, operating conditions, and device activity. Check the indicator lights regularly and replace the batteries when the device no longer operates normally.Q15: Does it require professional installation?A: No. The device can be secured with the included zip ties. However, all cables and devices must be firmly mounted away from hot, sharp, or moving vehicle components.Q16: What should I do if the device does not turn on?A: Check the AA batteries or power connection first. Confirm the cable is securely connected, then press the power button to restart the device. Excessive movement while switching it on may temporarily activate the vibration standby function.
