The Pyranha SprayMaster Insecticide Spray Complete Barn Kit is here to help keep insects away in a hassle-free process! The SprayMaster includes a 55-gallon unit with a half-horsepower electric motor-driven pump that is controlled by an electronic timer. When set, the timer notifies the SprayMaster to dispense a fine mist of insecticide formula into the air through the spray nozzle. Reaching up to 80 stalls, keeping insects away has never been easier!
