Python® Dust Refill

Control livestock ectoparasites with the powerful dual-action of Python II Dust. This unique formula combines two novel active ingredients for maximum efficacy against major pests like horn flies, face flies, and ticks. Zetacypermethrin, a 5th generation pyrethroid with enriched S-isomer content, provides potent initial control. Piperonyl butoxide, a photostable synergist, enhances zetacypermethrin's effectiveness and overcomes insect resistance for long-lasting residual activity, even in sunlight. This kit includes one A-line bag and a 12.5 lb PYthon II Dust refill bag.
