Chewed wiresdestroyyour car's engine.

Rats, mice, and squirrels see your warm engine as a nesting ground. Once inside, they shred expensive wiring harnesses and insulation, leaving you with thousands in repair bills and a vehicle that won't start when you need it most.

Repair Cost

The average cost to replace a main wiring harness destroyed by rodents in modern vehicles.

Vehicle Owners

Experience rodent-related damage to their cars, especially during colder months across the US.

24/7+

Active Protection

Yet most owners rely on smelly sprays that wash away or traps that require constant cleanup.

Expensive Repairs

Rodents love soy-based wire insulation, turning your car into an expensive snack.

Fire Hazards

Nests built near hot engine components are a leading cause of vehicle engine fires.

Ineffective Sprays

Mothballs and peppermint oils are messy, smell bad, and rodents quickly get used to them.

The Advanced Deterrent

Protection
withoutchemicals

AutexRat uses 3rd Gen ultrasonic frequencies and high-intensity strobe lights to create an environment rodents hate, keeping your engine bay clear 24/7.

Old Methods

Smelly Repellents

Peppermint oils and mothballs that make your cabin smell worse than the rodents.

Short-lived results

Sprays wash off or evaporate in days, leaving your engine vulnerable again.

Dangerous Traps

Traditional snap traps are messy, inhumane, and hard to set in tight engine spaces.

Basic Ultrasonics

Single-frequency devices that rodents eventually ignore after a few days.

"After squirrels chewed through the wiring on my SUV twice, costing me ,500, I installed the AutexRat. It's been 6 months and not a single rodent has come near my engine. The strobe lights really do the trick."

Mark Johnson

SUV Owner • Florida

"I'm a mechanic in Texas and I recommend these to all my customers. Most of the 'repellents' out there are junk, but the 3rd gen ultrasonic frequency in AutexRat actually works. It's easy to wire into the battery."

David Martinez

Lead Mechanic • Texas

"Perfect for my classic car in Ohio that sits in the garage for months. I use the battery option so I don't have to mess with the original wiring. The digital display makes it easy to check the power level at a glance."

No. The AutexRat features an ultra-low power consumption chip. The built-in vibration sensor turns the device off when you start your car and back on once it's been stationary, ensuring your battery stays charged.

Yes! The ultrasonic frequencies are targeted at rodents like rats and squirrels. While pets may hear a faint sound if they are right next to the engine, it is completely harmless and non-toxic to them.

When using 4 high-quality lithium AA batteries, the device provides continuous protection for up to 60 days in wireless mode. For permanent protection, we recommend the included 12V car adapter.

Absolutely. AutexRat is manufactured using industrial-grade, heat-resistant polymers specifically designed for under-hood environments. It is also splash-proof to handle road grime.

We recommend mounting it in the upper part of the engine bay, away from moving parts. Point the speaker and strobe lights toward the largest open area of the engine where rodents usually nest.

No. Once installed, it stays in 'standby' mode. It only activates its repellent cycle when it senses the car has been parked and stationary for a few minutes.
