The only dust to contain two novel active ingredients for maximum efficacy against all major livestock ectoparasites, PYthon II Dust in a kit will help make your life just a little easier.

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 II Dust contains a photostable formula of piperonyl butoxide for long-lasting activity in sunlight. PYthon Dust is an environmentally friendly dust for use on lactating and non-lactating dairy & beef cattle, sheep, goats and horses. The Dust controls horn flies, lice, ticks, and keds.
