JustiFLY® Liquid Feed™, the Best Fly Contol for Pasture Cattle and Feedlot Cattle

  • JustiFLY® Liquid Feed™ is one of the best cattle fly control products on the market. The insect growth regulator (IGR) larvacide feedthrough can effectively control stable flies, horn flies, face flies and house flies.
  • Simply add JustiFLY® Liquid Feed™ to your liquid feeder, and the IGR larvacide will go to work once deposited in manure.
  • JustiFLY® Liquid Feed™ provides 300 feedings per pound of additive—a cost of less than $0.07 per head per day—and is approved for both pasture and feedlot cattle.
