JustiFly Feedthrough

JustiFly is an economically priced Insect Growth Regulator feed-through, non-toxic larvicide for pasture cattle and feedlot cattle that controls stable, horn, house, and face flies for pennies per head per day. Just mix and feed. No oily insecticides, dusts, or sprays; zero animal-handling stress. No withdrawal period. No milk disposal issues. Active ingredient, Diflubenzuron, affects the fly by inhibiting chitin, which retards the development of their exoskeleton, thus causing death shortly after they hatch.
