www.ratocop.comRatocop is designed using specialized sensor modules to detect presence of rats, mice, squirrels and other Rodent species which are likely to enter into Cars and other vehicles through openings beneath the bonnet and damaging wires and other parts of the engine.
Ratocop detects the slightest presence of any rats and mice in the engine area and creates random vibrations and noises similar to engine ignitions, hence the rodent is scared away due to irritation and fear assuming the vehicle to have started, thus giving the rat no chance to damage the wiring’s and fittings of the car.
This device will be automatically switched "ON" & “OFF” The entire installation is done by connecting only two wires to the car battery, without tampering any original wires of the car
