Stop flies at the source with Farnam SimpliFly Feed-Thru Fly Control Pellets Horse Supplement. This palatable, alfalfa-based supplement interrupts the fly life cycle where they breed—in your horse’s manure. The active ingredient passes straight through your horse and deposits in manure, preventing fly larvae from developing into adult flies. SimpliFly provides barn fly control and stable fly reduction without sprays, wipes, or topical treatments. It’s safe for daily use in all horse breeds and is easy to mix into regular feed. Plus, you’ll feel good knowing it contains no organophosphates. For best results, early spring before flies appear and continue through summer and fall. Check out Farnam’s full line of insect control solutions for comprehensive barn fly protection.
