The Rodent Terminator Wireless Accessory Receiver makes it easy to know when your Rodent Terminator works when you put it in those hard to reach places where rats and mice like to live. It's a snap to install -- in less than two minutes, with only a Phillips screwdriver, you can easily add remote monitoring to your Rodent Terminator. The receiver plugs into a standard 110V outlet and the sending unit is powered by the batteries in your Rodent Terminator. Battery life may be reduced by 10% as a result of the WAR device being installed. The monitor will instantly sync with your Rodent Terminator once it is baited and set, and it will instantly let you know when there is any change in status - including successful kill and low battery.
