Stop mice, rats, and squirrels from chewing through expensive underhood wiring. AutexRat delivers 24/7 continuous defense with 3rd Gen ultrasonic waves and dual-color flashing strobe lights to keep your engine room pest-free.










Mice and rats love chewing modern soy-based wiring insulation. AutexRat emits high-frequency ultrasonic waves that completely irritate and deter pests, forcing them out of your vehicle's engine bay before they chew through critical electronics.
Never worry about defense gaps. Power AutexRat your way: connect directly to your car's 12V adapter line, run it via standard USB, or power it with four AA batteries for long-term garaged vehicle protection.


Engine compartments represent an incredibly harsh climate. AutexRat is built with durable, premium materials that protect its advanced digital circuitry from moisture, dust, intense under-hood heat, and cold temperatures.



The AutexRat 3rd Gen system is a major technological leap forward in vehicle preservation. By combining dynamic, high-frequency ultrasonic waves with highly disruptive flashing visual alarms, it efficiently breaks the nesting patterns of destructive pests before they damage engine room wiring looms.

Never lose protection. Run your device on your vehicle's 12V adapter, plug it into a standard USB charger, or power it with four AA batteries for long-term garage storage.

Measuring only 12 × 8 × 3 cm, its miniature footprint fits securely inside any tight engine bay space without obstructing moving automotive mechanisms.

An eco-friendly, clean, and completely non-hazardous solution. Ditch messy traps, toxic chemical sprays, and poisonous baits that put your pets and children at risk.


Rodents are nocturnal pests highly sensitive to flashing lights. The high-intensity red and blue strobe lights disrupt their night vision, making nesting impossible.

No guessing games. Monitor your device status with ease. The integrated digital screen clearly displays active frequencies, current power options, and system health.

No wire-cutting or professional mechanics needed. Mount securely using the included zip ties to keep your factory engine warranty fully intact.









We are fully dedicated to protecting your vehicle's critical electronics. Our responsive automotive support specialists are standing by 24/7 to help you with installation, setup, or technical power questions.
Everything You Need to Know About Underhood Rodent Defense






Rats chewed through the main wiring loom of my truck twice, costing me thousands. Since installing AutexRat six months ago, my engine bay is completely pristine—not a single dropping or mark. The 12V connection was incredibly simple to run!

I store my convertible in a detached garage for the winter and always worried about mice. I use the AA battery power option on my AutexRat repeller, and it keeps the car 100% rodent-free. Absolute peace of mind!

The build quality of this repellent unit is fantastic. It easily handles under-hood heat, and the digital status screen gives me confidence it is working. Far superior to cheap battery-powered pest sounders that die in days.
