Highlights
- 【Physical Rodent Repellent& Pest Deterrent】This rodent repellent for car engines uses variable frequency ultrasonic and LED strobe lights to effectively repel mice, rats, squirrels and other rodents away from your car. Usage: If the device works in TEST mode, its strobe lights and speaker are functional, it will operate correctly in Ultra mode
- 【Intelligent Vibration Sensor】When the ultrasonic rodent repeller detects that the car has started, it automatically stops working to save battery power. Conversely, when the car is turned off and no vibration is detected, the ultrasonic rodent repeller reactivates immediately, ensuring continuous protection for your vehicle
- 【Friendly to Humans and Pets】This ultrasonic rodent repellent is non-toxic, harmless, and chemical-free. The car engine mouse deterrent emits high-frequency sound waves ranging from 25kHz to 55kHz, which specifically target rodents' auditory and nervous systems. As these frequencies are beyond human and pet hearing ranges, the mice repellent indoor device works silently and safely around households
- 【Safe and Effective】This rat repellent for car combines ultrasonic and strobe lights, which can simultaneously or alternately generate variable-frequency ultrasonic and strobe lights to stimulate the nervous system and auditory system of rodents, disrupting their preferred dark, quiet environments and causing discomfort that drives them away from your vehicle
- 【Multi-Purpose Use】This rodent repellent for cars can withstand extreme temperatures and harsh weather conditions, providing reliable long-term protection. Not only is it designed for placement under your car’s hood, but it can also be installed in warehouses, attics, garages, basements, storage rooms, and various other locations to effectively deter rodents.

Detailed Review
The WAYSLA Ultrasonic Rodent Repeller 2-Pack offers a physical, chemical-free defense system designed to keep mice, rats, squirrels, and other pests away from engine bays. For vehicle owners dealing with unwanted visitors under the hood, these compact units disrupt the dark, quiet environments that pests prefer.
Each device pairs variable-frequency ultrasonic sound waves ranging from 25kHz to 55kHz with bright LED strobe lights. These alternating stimuli target the nervous and auditory systems of rodents without using toxic chemicals. Because these frequencies fall outside the normal hearing ranges of humans and household pets, the devices operate safely and silently inside garages, basements, attics, or storage rooms.
Power management is handled through an integrated vibration sensor. When you start your engine, the repeller senses the vibration and turns off to preserve vehicle battery power. Once you park and the vehicle is turned off, the sensor detects the lack of movement and immediately reactivates protection.
While built to withstand extreme temperatures and harsh weather conditions under the hood, the product data does not specify exact power wiring requirements or battery sizes. Buyers should note that setup relies on the included cable ties to secure each unit in place.
Verdict: The WAYSLA 2-Pack is a practical, non-toxic deterrent for drivers and homeowners looking to guard engine compartments, garages, or storage areas from nesting rodents without using chemical poisons.
