"After squirrels chewed through my truck's wiring harness and cost me $1,800 last winter, I bought AutexRat. It took two minutes to mount with zip ties. Not a single trace of droppings, acorns, or rodents since! Absolute lifesaver."

"I store my classic car and camper in an unheated pole barn where field mice are everywhere. I run AutexRat with 4 AA batteries and check it weekly. The digital screen shows the battery status, and it completely keeps mice away."

"The combination of ultrasonic sound and the flashing red/blue LEDs works like magic. My car is parked outside near woods and we used to find acorn piles under the hood every week. Since installing this, zero pest visits."
