Frequently Asked Questions

How does the ultrasonic system protect my vehicle's engine room?

RepellCar uses advanced 3rd Gen technology to emit variable high-frequency ultrasonic waves. Safe and silent to humans, these sound waves create an intensely irritating environment for mice and rats, driving them away from your engine. 

Will connecting RepellCar to my car's battery drain it?

No. The unit uses extremely low-power circuitry and features integrated low-voltage protection. If your car battery's charge drops below a safe limit, the device automatically pauses to ensure your battery never drains.

Can I power it without connecting to the vehicle's 12V lines?

Yes, completely. It features triple-power options, allowing you to run the device using 4x AA batteries or via a standard USB connection, making it perfect for stored cars and trailers.

Is this mouse repellent for car safe around family pets?

Yes. The ultrasonic frequencies are scientifically targeted at the hearing range of small wild rodents. It is completely safe, eco-friendly, clean, and silent to humans, dogs, and cats.

How long does the installation take?

Installation is quick and easy, taking under 5 minutes. Secure the compact unit inside your engine room using the included heavy-duty tie bands, choose your preferred power source, and turn it on.

Is the housing built to handle extreme engine bay heat?

Yes, absolutely. The casing is constructed from robust, water-resistant, and high-temp heat-retardant materials, engineered to handle intense under-hood environments and extreme climate conditions.

How do the flashing strobe lights help deter pests?

Mice and rats are highly sensitive to sudden, bright visual disruptions. The dual-color red and blue LED strobe lights flash intensely, destroying their sense of security and making nesting impossible.

What is the product warranty?

The product comes with a 1-year warranty. Returns and exchanges are supported within 30 days. Customers can feel secure using the product.
