Fly Control — Frequently Asked Questions
What's the best way to keep flies off my horse?
A layered approach works best. Combine a good fly spray for direct protection, a fly sheet and fly mask for physical coverage, and barn management like regular manure removal to cut breeding sites. No single product stops every fly, so most horse owners rotate several methods through the season and reapply repellents as sweat and turnout wear them off.
How do feed-through fly control supplements work?
Feed-through fly control mixes an insect growth regulator into your horse's daily feed. It passes through the digestive system into the manure, where it stops fly larvae from developing. Because it targets the breeding cycle rather than adult flies already on your horse, it works best barn-wide, started early in the season, and paired with sprays or traps for flies drifting in from nearby properties.
How do I reduce flies in my horse barn?
Reducing barn flies starts with removing the breeding ground. Clean manure and wet bedding often, keep water troughs from overflowing, and store muck away from the stalls. Good airflow and fans make it harder for flies to land and settle. Traps placed away from stalls draw flies out of the barn, while feed-through products and sprays handle what management alone cannot.
