A flying insect spray apparatus includes a casing having upper and lower portions that define an interior area. The casing may be mounted to a wall or ceiling of an enclosed structure such as a garage. A reservoir configured to hold an insecticide is positioned in the interior area, the reservoir having an outlet such as a hose. A pump is positioned in the interior area and electrically connected to the reservoir and configured to cause the insecticide to be urged from the reservoir when the pump is electrically actuated. The outlet is in fluid communication with a plurality of nozzles spaced apart radially about a dispensing member such that the insecticide is dispersed in a 360 degree radius of the casing. The spray apparatus includes a controller electrically connected to the pump that includes a timer, the controller configured to actuate the pump at a predetermined time.
