Python Dust is a powdered livestock insecticide built around two active ingredients, zeta-cypermethrin and piperonyl butoxide, that work together to control a range of external parasites. It is labeled for use on lactating and non-lactating dairy cattle, beef cattle, sheep, goats and horses. The dust can be applied directly from the 2 lb shaker can or dispensed through a dust bag, dusting glove or mechanical dust applicator, giving producers flexibility depending on herd size and handling setup. Application is worked into the hair over the head, ears, neck, shoulders, back and tailhead, with a smaller amount placed inside the ears for spinose ear tick control. The piperonyl butoxide component is formulated to remain stable in sunlight, supporting continued activity between treatments. No mixing or assembly is required before use, and treatment can be repeated as needed on a label-directed schedule.
