JustiFLY Fly-A-Salt Cattle Fly Control Block with Salt, 20 lb

JustiFLY® Fly-A-Salt is a convenient, stress-free fly control solution for cattle at all life stages. Each 20 lb salt block provides 320 feedings—one block feeds 5 head for approximately 2 months. Cattle naturally ingest the larvicide while consuming salt, which then works in the manure to break the fly life cycle. No animal handling, sprays, pour-ons, dust bags, or ear tags required. Safe for pasture and feedlot use with zero withdrawal period and dung beetle safe formulation. At less than 10 cents per head per day, it's an affordable, effective way to control flies throughout the season with minimal effort.
