Python Dust in the only dust to contain two novel active ingredients for
maximum efficacy against all major livestock ectoparasites. Zetacypermethrin is a 5th
generation pyrethroid with enriched S-isomer content that is highly active against
horn flies, face flies, ticks and other pests. Piperonyl butoxide is a mixed-function oxidase
inhibitor that helps overcome metabolic resistance in insects 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.
