Automatic pesticide, insecticide, repellant, poison, air freshener, disinfectant or other spray-type delivery systems are proposed for automating the delivery of these items to areas, for controlling pests easier, for improving environmental conditions, and for making it easier to freshen the air and to disinfect areas. The device includes a logic circuit and mechanisms containing a circuit that will enable a user to program the device to discharge a spray of its poison, disinfecting or air freshening spray(s) at a pre-selected time interval or day/time interval chosen in the unit's memory. An electromechanical valve opens to let contents escape when the spraying mechanism of the system is activated. The valve connects to a pressurized spray cylinder and it releases a controlled burst of insecticide, pesticide, repellant, disinfectant, and or air freshener as programmed. Control circuits allow the user to set when the system goes off.
