INDICATIONS

• Target Pests: Effectively controls four major fly species: horn, stable, house, and face flies.
• Life Cycle Disruption: Works by inhibiting chitin formation in fly larvae, preventing them from maturing and emerging from manure.
• Application: Mixed into liquid feed or mineral supplements for continuous, low-stress feeding.
• No Animal Handling: Reduces stress and labor compared to sprays, pour-ons, or ear tags.
• No Withdrawal: No milk or meat withdrawal period, and safe for beneficial dung beetles.
• Broad Use: Approved for pasture, feedlot, stocker, and slaughter cattle, including veal calves. 

ADMINISTRATION

• Mix: Combine one JustiFLY add-pack (e.g., 360g) with one 50-lb bag of your cattle’s usual free-choice mineral supplement. A pre-mixture is recommended for even distribution.
• Feed: Place the treated mineral in feeders, ideally near water sources or resting areas.
• Quantity: Use one feeder for every 15-20 head of cattle, and protect feeders from weather.
• Timing: Start feeding in spring before flies appear and continue until cold weather ends the fly season.
