Note: Pro-Tech’s natural insecticide and odor control solutions are specially formulated for Pro-Tech’s spraying systems with safety and performance in mind. They will not damage the seals and o-rings found throughout the pump, valves, and spray nozzles. Nor will they separate out of solution in the reservoir and tubing, therefore, you will receive optimum performance with no nozzle clog. Using solutions other than Pro-Tech’s voids your warranty.
