flies, ticks and other pests. Piperonyl butoxide is a mixed-function oxidase inhibitor that helps overcome metabolic resistance in
insects and and synergizes the zetacypermethrin for maximum efficacy and residual activity. PYthon dust contains a photostable
formula of piperonyl butoxide for long-lasting activity in sunlight.
