Don't let rats and mice chew through your expensive engine wiring. AutexRat provides non-stop, advanced 3rd Gen ultrasonic defense and smart flashing strobe alarms to keep pests out of your underhood areas 24/7.




Rats and squirrels chew modern soy-based wiring, leading to complete vehicle failures. AutexRat's 3rd Gen ultrasonic frequency intensely irritates pests' nervous systems, driving them away before they nest in your engine bay.
Secure your vehicle under any circumstances. AutexRat runs smoothly on your car's 12V adapter, a portable USB power bank, or 4 AA batteries—guaranteeing 24/7 underhood defense even when your engine is completely off.


Your car's engine bay experiences intense changes in climate. AutexRat is built with durable, heavy-duty weather-resistant housing that guards its advanced micro-circuits from intense engine heat, environmental moisture, and road dust.



"The AutexRat 3rd Gen repeller is a game-changer for engine maintenance. By seamlessly combining ultrasonic sensory irritation with powerful strobe visual alerts, it breaks the rodent nesting pattern before they chew through critical wiring components."
– Raymond Fletcher, Research Specialist

At just 12 × 8 × 3 cm, it fits comfortably into tight engine bays of compact cars, SUVs, high-end sedans, and heavy-duty work trucks.

Everything You Need to Know About Vehicle Engine Bay Protection






I live in a rural suburb and rats ruined my truck's wiring twice, causing thousands in damages. Since installing the AutexRat device six months ago, I haven't seen a single nesting sign or dropping in the engine bay. The 12V connection is brilliant!

I store my classic roadster in a shed for winter and mice used to be a massive headache. Now I just use AA battery power with this repellent, and the engine stays clean. Worth every penny of investment.

The product quality is superior. It easily handles under-hood heat and the digital interface keeps me updated on current modes. It is much more durable than cheap plastic options.
