A mosquito misting system is described having a liquid reservoir that is operably associated with a fluid pump and motor and fluid conduits to transmit a fluid insecticide to one or more dispersal nozzles. A controller is used to control the frequency and duration of dispersal. An agitator device is preferably associated with the fluid reservoir to adequately agitate the insecticide mixture within the reservoir during or just prior to dispersal of the fluid insecticide. The controller is interconnected with a level sensor assembly to provide a graphic indication of the level of fluid insecticide remaining in the reservoir. Additionally, the misting system is provided with a fluid pressure switch that detects a rupture in the fluid conduit and prevents further flow of fluid from the reservoir. In further aspects, the system is provided with remote control and, optionally, a remote monitoring feature that allows improved service and maintenance for the system.
