A rodent deterrent that needs no wiring. Six high-voltage contact plates, random ultrasonic bursts and flashing LEDs, all powered by four AA batteries that last about a year. Nothing connects to your vehicle's electrical system, so it can't drain your battery.

German-engineered for engine bays. A built-in vibration sensor switches it on when the vehicle is parked and off when the engine runs.

How it works

The plates mount where rodents get into the engine bay: along hoses, near the firewall, by the battery tray and around wiring that's already been chewed. Each plate is dual-pole, so an animal gets a startling pulse as soon as it touches both contact surfaces, even if it isn't standing on bare metal. Single-pole plates only work when the animal is also touching the vehicle's body.

The ultrasonic signal fires at random intervals, roughly every 9 to 30 seconds, and shifts between about 21 and 24.5 kHz. The randomness matters because rodents get used to a steady, predictable sound. Treat the sound as a supporting layer. The plates do the real work.

Who it's for

Vehicles that sit: summer cars in storage, RVs, boats, trailers and anything parked outdoors or in a barn. It also suits vehicles you'd rather not wire into, such as leases, because nothing connects to the vehicle's electrical system.

Cold weather

Rated from -20 °C to +80 °C. That covers fall, when mice move into cars, and garaged vehicles all winter. On the coldest nights, a vehicle parked outside can drop below the rated range. AA batteries also lose capacity in deep cold, so check the battery LED more often in winter.

Installation

Mount the control unit with self-tapping screws or strong double-sided tape, away from exhaust heat and moving parts. The plates run on 4 metre cables. No wiring to the vehicle is needed, but plate placement decides how well it works.

There is no hood switch. Turn the unit off with its side switch before anyone works in the engine bay.

Rather have us fit it? Book an install at our Markham shop, and we can wrap exposed harnesses with capsaicin rodent tape while we're in there. Already chewed? We repair rodent-damaged wiring too.
