• Mice, rats, and squirrels can cause thousands of dollars in damage to the wiring under your hood. This ultrasonic repeller emits powerful 18–36 kHz sound waves and features a bright flashing LED light, targeting rodents’ sensitive hearing and vision to drive them away—all without the hassle of using traps. Simply secure it with the included zip ties, and you won’t have to worry about it afterward—
• Three Power Options for Any Vehicle — No matter what you drive, this repellent has you covered. Power it with 4 AA batteries (lasts over 3 months in standby mode), plug into any 5-12V USB adapter, or connect directly to your vehicle's under-hood power outlet with the included DC cable. You're never left without protection, whether you're parking in your garage or on the road.
• Smart Vibration Sensor Saves Battery — The built-in vibration sensor detects when your engine starts and automatically puts the device into standby mode—the red indicator light stays on so you know it's working. Within 90 seconds of parking (when vibrations stop), it resumes full operation without any manual reset. This smart design extends battery life and means zero hassle for you.
• 100% Safe For Family & Pets — Operating at 18,000–36,000 Hz, the ultrasonic frequencies are completely inaudible to humans and won't bother dogs, cats, or birds. Unlike poisons or traps, there's no risk to children or pets. Just effective, humane rodent control that works while you sleep.
• Versatile Use—Under The Hood & Beyond — Compact enough to fit in any engine bay, this repeller also works great in garages, attics, basements, storage rooms, barns, RVs, boats, and sheds. The included zip ties make installation quick and secure on virtually any vehicle or surface. One device, multiple protection zones.
