Don't let rodents turn your car's wiring into a snack. AutexRat provides 24/7 advanced ultrasonic defense and strobe light deterrents to keep rats, mice, and squirrels out of your engine bay for good.




Rodents love chewing on modern soy-based wire insulation. AutexRat emits irritating high-frequency waves that make your engine bay the last place a rat wants to nest, saving you from expensive mechanical bills.
Whether your car is running or parked for the winter, AutexRat stays active. Choose from 12V vehicle power, USB, or AA batteries to ensure your underhood area is never left vulnerable to intruders.


Engine bays are harsh environments. AutexRat is built with high-grade, water-resistant materials designed to withstand engine heat, dust, and moisture, ensuring long-term protection in any climate.



"The AutexRat 3rd Gen system is a breakthrough in preventative vehicle maintenance. By combining ultrasonic frequencies with visual strobe deterrents, it effectively breaks the nesting cycle of rodents before they can cause catastrophic engine failure."
– Mark Stevens, Research Specialist


Flexible power options mean your vehicle is protected in any scenario, from daily commuters using 12V to seasonal cars in storage using batteries.

The compact 12 x 8 x 3 cm design ensures a perfect, discreet fit in everything from compact sedans and luxury cars to heavy-duty trucks.

A clean, eco-friendly alternative to messy traps or poisonous chemicals that can be dangerous to pets and the environment.


Rodents are nocturnal and sensitive to light. Our flashing Red and Blue LEDs create an environment where they simply cannot settle down.

Manage your protection with ease. The clear digital screen shows you exactly which mode is active and the current power status of the device.

No professional help needed. Mount it anywhere in the bay in minutes with no wire cutting required, maintaining your car's factory warranty.









We are dedicated to your vehicle's safety. Our US-based support team is available 24/7 to help with installation or performance questions, ensuring your engine remains a rodent-free zone.
Everything You Need to Know About Rodent Defense






I live in a rural area and rats ate through the main harness on my truck twice. Since installing AutexRat six months ago, I haven't seen a single dropping or chew mark. The 12V connection was super simple to set up.

I store my vintage convertible for the winter and was always worried about mice. I use the battery power option for AutexRat while it's in storage and it works perfectly. Peace of mind is worth every penny!

The build quality is impressive. It stands up to the heat of the engine bay and the digital display makes it easy to see that it's working. Much better than those cheap battery-only units that die in a week.
