the CARCAT story

1st Gen CARCAT
Ultrasound rat repellent (Launch)
2nd Gen CARCAT-Duo
Ultrasound + LED (White) strobe
Rat repellent system - ZigZag Ultrasound + Blue/Green LED strobe
What happened to 3rd Gen CARCAT?

CARCAT - 3rd Gen was planned to launch in quarter-1 of 2020. But corona happened. The lockdown gave us time to up our research & development cycle and double the upgrades.

This new cat on the block (4th Gen) has an all-round – Hardware + Firmware + Enclosure upgrade.

Back in 2015 we could have never imagined CARCAT would evolve from just a rat repellent into a more complex rat repellent ‘system’, which also safeguards and monitors the cars battery for optimum use.

This would not be possible without the support and feedback from our valued customers and CARCAT fans.

Why do rats love your car’s engine area?
Rats being nocturnal animals come out from their day dens (sewers & gutters) at night in search of food. Your vehicle's engine area is a safe 2nd home to take food stuff and eat in peace – away from cats / dogs. Post dinner they have a necessary teething need to sharpen the insides of their front incisor teeth. Failing which can be life threatening, cause their incisors grow at a rate of about 3 inches annually. The near endless supply of cables & wire under the hood ensures they have a juicy chew all night. Your car even has essential and clean water supply in the wiper spray ducts. Read More
It's tough to get rid of rats
Research shows rats depending on their species, share around 92 to 95% of their working DNA with us, humans. They are very intelligent and extremely territorial animals. No wonder, rats are one of the toughest pest to get rid of. Rats are one of the most resilient and under estimated creatures on earth. They were here long before any human species walked the earth and they will probably be around long after we are wiped out. No wonder- they are one of the hardest pests to get rid of. There is probably no 100% way to get rid of them, but with each new upgrade we use that understanding to try and reach closer. Read More

Virtual simulation

CARCAT-RED has user configurable features. Depending on the features enabled and current car battery voltage CARCAT-RED will enter different modes. Virtual simulation allows user to change configuration and battery voltage to simulate conditions for those modes.

the science

Ultrasound is no rocket science. Ultrasound generators have been around since the time of discovery of piezoelectricity by Jacques and Pierre Currie in 1877. Ultrasound generators exploit the piezoelectricity effect (electrical to mechanical energy conversion and vice-versa) of certain crystals to produce vibrations at ultrasonic frequencies.

Rat and rodents like bats and dolphins can hear and create ultrasound. They use ultrasound for echo location, long range communication, mating calls, aggression and distress signalling.

Human safety, our priority

Built as per the IRPA (International Radiation Protection Agency), Geneva, guidelines, CARCAT is completely safe for humans. In simple words, humans can be exposed to CARCAT’s ultrasonic frequencies without having any side effects.

Legal Disclaimer

As per the feedback from our huge global customer base, CARCAT has an efficacy of around 94% for cars with existing rat problems. Efficacy for CARCAT installed in cars with non-existing rat problems (proactive prevention / newly purchased cars) is 4 to 5% higher.

This is way more than any rat poison or sprays can provide on a 24hrs / 365 days basis. However, a proactive approach is recommended. Rats may sometimes enter the engine area due to a survival need like escaping from a cat / dog or flooding during monsoon season. They will not be able to withstand CARCAT for long, and user may occasionally see paw marks or rat urine and faeces.

User is advised to get it cleaned up. This is how rats mark territory. Once they start thinking your car is their domain, they will try to resist the ultrasound and strobe LED distress. In a worst-case scenario, they may even chew on something due to the agitation caused by CARCAT, as chewing de-stresses them. But our experience and customer feedback show the extent of damage caused would be far less than without CARCAT installed.

CARCAT is powered by the car’s battery. Although, the power drawn is very small and can power CARCAT for 15-20 days (depending on Ah capacity/age/charge status) without affecting cranking power. It is still recommended to give a good run to the car at least once a week, to keep the battery optimally charged.

With a efficacy of over 96% and 24,000+ happy customers in India and globally, CARCAT comes 2nd to none, making it the most trusted method to safeguard wires and ducts under the hood of your vehicle from rats.
