Fly Season Management: Building a Summer Routine for Horses

If there’s one thing every rider can count on once summer hits, it’s flies showing up the second a horse starts sweating.

Between turnout, long days at the barn, horse shows, and humid weather, fly season becomes part of the daily routine pretty quickly. And while there’s no single “fix” for flies, most riders end up building systems that help make summer management a little easier.

For some barns that means changing turnout schedules. Others rely heavily on fans, fly gear, grooming routines, or feed-through support products. Usually it’s a combination of all of it.

Why Summer Makes Fly Management Harder

Warm temperatures, moisture, standing water, manure, and sweat naturally create more activity during the summer months. Horses in heavier work or traveling frequently may also spend more time exposed to flies, especially during early mornings and evenings.

And honestly, horse shows can make things worse.

Temporary stalls, packed barns, humid weather, and long days outside tend to create the perfect environment for summer fly problems to ramp up quickly.

Small Barn Habits That Make a Difference

Most riders know the little things tend to matter most during fly season.

Things like:

• Dumping standing water regularly

• Keeping stalls picked

• Using fans in the barn

• Rinsing sweat after rides

• Cleaning feed areas

• Staying ahead of turnout gear and fly masks

None of it is groundbreaking, but consistency usually matters more than trying to overhaul everything at once halfway through July.

Feed-Through Fly Support

Alongside sprays and topical products, some riders choose to include feed-through fly support as part of their overall summer routine.

Forget Flies In-Feed Solution from Equine America is designed to be incorporated into a horse’s regular feeding program during the summer months as part of a broader fly-management approach. It's also a great alternative for horses that aren't a fan of sprays.

For many horse owners, products like this simply become one piece of the overall routine alongside turnout management, stable maintenance, and grooming.

Horse Show Weeks = Different Management

A lot of riders notice they need a completely different setup once show season starts.

At home, you know your turnout schedule, airflow, and barn routine. At shows, everything changes:

• Different stalls

• Different footing

• Different weather

• More horses

• More standing water

• Longer days outside

That’s usually why people end up simplifying their routines and packing ahead. Fly spray, extra masks, wipes, fans, feed tubs — it all suddenly becomes essential.

And if you’ve ever forgotten fly spray at a summer horse show, you probably only do it once.
