A method and apparatus for insect control by delivery of fluids combined from different sources is disclosed, wherein a first fluid is provided in a cartridge configured with a first fluid coupling and a first wireless transmitter (FWT), and a second fluid, or diluent, is supplied to form a mixture for distribution or spraying. The FWT is programmable with data identifying the composition and volume of the liquid in the cartridge and able to contain data of withdrawal of fluid or pump cycles. An interrogator or second wireless transmitter (SWT) communicates with the FTW to control the fluid withdrawal and mixing process. In addition, the combination of the cartridge identification and the coupling design restrict introduction of improper materials into the system, and potentially to an inhabited area.
