The Champion JustiFLY Feed-Thru Insect Control Cattle Supplement is an economically-priced insect growth regulator (IGR) larvicide that breaks the life cycle of all four fly species that affect cattle. The add pack is added to a 50-lb bag of free-choice mineral. The larvicide in the fly control for cattle is ingested by the cattle as they feed on the treated mineral throughout fly season. The fly pest control passes through the animal and starts to work on flies in the cattle manure. Made in the USA.

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.

  • Broad Spectrum - Controls ALL 4 species of flies that affect cattle: stable fly, horn fly, face fly, house fly
  • Tested - EPA approved for pasture cattle, feed yard cattle and dairy cattle
  • Confidence - Fly pest control approved for use in lactating dairy cattle; no withdrawal period; no milk disposal issues
  • Safety Margin - No known fly resistance
  • Economical - Full season fly control for cattle for less than 6 per head per day
  • Convenient - zero animal handling stress
  • Simple 1-to-1 mixing - Just add 1 add pack to one 50 lb. bag of loose mineral

It works!

6 years ago
We've been using this product for about a year now and I can honestly say it works better than any fly product we've tried. In the worst part of fly season last summer, our cows had hardly any flies on them. We are in Texas so we are already using it again this spring. And all we do is add it to mineral we are putting out anyway.

Can’t understand mixing instructions.

4 years ago
It says to mix a 360 gram pack with 50 lbs feed but then it is completely unclear how the mix is to be fed. Common description would for ex be to then feed to cattle so many ounces per head or per hundred pounds (preferred).

    Works for horses

    a year ago
    Mix this with a bag of mineral salt, give a handful each day with grain and greatly reduces the flies around my horses. Whenever I run out, the flies increase exponentially, so I know it works!
