Horse Fly Control Guide for Texas Summers

If you own horses in Texas, fly season isn't a season — it's a way of life. From March through November, flies are a constant battle. A layered fly control approach makes a huge difference for your horses' comfort and health.

A good fly spray concentrate mixed with water is your first line of defense. Apply before turnout and reapply after sweating or rain. Pyrethrin-based sprays work well for most flies. For horn flies specifically, look for products containing permethrin.

Fly masks protect your horse's eyes and face — the most sensitive areas. Look for masks with ear coverage and nose protection for full face defense. UV protection built into the mesh helps protect horses that are sun-sensitive.

A quality fly sheet like the TuffRider NevaTear provides full body coverage. The self-healing fabric repairs small tears automatically — important for horses that are hard on blankets in Texas brush country.

Remove manure frequently, eliminate standing water, and use fans in the barn. Flies breed in moisture and organic matter. A clean barn dramatically reduces fly pressure year-round.
