CARCAT DUO technology

CARCAT Duo is the perfect solution to get rid of rats. Its ultrasound technology and strobing white LED work together to give you double protection against rodents.

Ultrasound is a spectrum of sound which starts just above human hearing (20Hz to 20 kHz) range. Rats/bats/squirrel/dolphins have the ability to detect ultrasound with varying frequency ranges. Rats use ultrasound for communication (distress signalling/mating calls). CARCAT Duo bombards ultrasound waves with unique patterns which confuses and scares the rat. Ultrasound acts like a jamming signal shutting down the rat’s night navigation system and communication with other rats. It also emits distress signals which further scare the rat away from entering the vehicles engine area.

Strobing LED causes a continuous optical distress by not letting the rat’s eyes adjust to the constantly changing light conditions inside the engine bay area. So even if a territorial alpha rat is brave enough to challenge the ultrasound threat to its home (your car) the combined light and sound effect would prove too much of a challenge to stay and chew on wires and ducts.

CARCAT’s Duo technology attacks the rat’s 2 most vital senses – hearing and sight. Making it doubly confused, scared and disoriented. Forcing it to leave and keep away from the vehicle for good.
