JustiFLY® Feedthrough 360 gram

Champion Animal Health



The Fly Control for Cattle Mineral Add-Pack that Makes Keeping Flies Away Easy

  • JustiFLY® Feedthrough is more effective than typical cattle fly control pour-ons for breaking the lifecycles of all four common types of cattle flies.
  • This fly control mineral add-pack costs less than 6 cents per head per day.
  • JustiFLY® is approved to control flies for both lactating and non-lactating cattle, as well as for use in both pasture and feedlot cattle.

JustiFLY® Feedthrough Benefits

  • This fly control for cattle mineral add-pack effectively prevents the development of horn flies, face flies, house flies and stable flies in manure.
  • JustiFLY® can also be used to control existing adult flies around manure.
  • JustiFLY® Feedthrough can be used throughout the fly season in both non-lactating and lactating dairy cattle.
  • JustiFLY® can reduce animal-handling stress.
  • The fly control add-pack does not affect dung beetles.
  • The fly control mineral easily passes through a cow’s system leaving no residue, requiring no withdrawal period and causing no resistance issues.
  • JustiFLY® is more effective and easier to use than dust bags, ear tags, sprays, and cattle fly control pour-ons.

How to Use JustiFLY® Feedthrough

  • Mix one add-pack with one 50-lb bag of free-choice mineral and feed your cattle with the mix.
  • Cattle ingest the IGR larvicide as they feed on the treated mineral. It passes through the animal and starts to work on flies once it is deposited in the cattle manure.
  • On average, each 360 gm. (12.7 oz.) add-pack treats 2 animals for 6 months (3 add- packs = 6 animals for 6 months)
