Fly Gear

Fly gear is one of the most important categories in warm-weather horse care. A good fly mask, fly sheet, and fly boots working together can dramatically reduce the stress, skin damage, and health risks that come from insect pressure during spring and summer. Flies aren't just annoying. They spread disease, cause eye irritation, and create the kind of constant discomfort that makes horses hard to manage, impossible to keep weight on, and reluctant to stand still. The right fly protection changes that.

Fly masks are the foundation of any fly gear system. They cover the face, eyes, and often the ears and nose, using fine mesh that horses can see through clearly but that blocks insects from landing on sensitive facial skin. Full-face fly masks with ear and nose coverage provide the most complete protection, while basic eye-only styles work well for horses that are mildly bothered. UV-blocking fly masks add sun protection, which is particularly valuable for horses with pink skin or light-colored faces.

Fly sheets cover the horse's body to keep insects from biting through the coat. Today's fly sheets are made from lightweight, breathable mesh that provides protection without trapping heat. Some fly sheets include UV protection to prevent coat bleaching, belly bands to keep the sheet from shifting, and neck covers for full coverage. If your horse lives
out in summer, a fly sheet dramatically reduces the constant tail-swishing, stomping, and skin irritation that come from unprotected turnout.

Fly boots, sometimes called fly wraps or fly socks, cover the lower legs to protect against the gnats and insects that congregate around the legs and pasterns. They're especially useful for horses that stomp constantly during turnout, a habit that over time can cause concussive stress to joints. Look for fly boots with stay-put closures and breathable material that won't overheat the lower leg. Together, a full fly gear system
gives your horse's entire body protection so they can relax, graze, and focus during the season when insects are most intense.

Frequently Asked Questions

Do fly masks hurt horses or impair their vision?
No. Quality fly masks are made from mesh that horses can see through clearly. The material filters UV light and blocks insects without significantly reducing visibility. Horses generally adjust to fly masks within a short time and many come to the gate wanting theirs put on during fly season. The key is proper fit: a mask that is too tight can rub around the eyes and cause sores, while one that's too loose can shift and actually obstruct vision. Check fit at the eye cutouts and across the nose daily.

Can horses wear fly sheets in hot weather?
Yes, and modern fly sheets are designed specifically for hot-weather use. They're made from open-weave mesh that allows airflow while creating a physical barrier against insects. Research and owner experience both suggest that horses in fly sheets are often calmer and less stressed than unprotected horses during peak fly season because they're not constantly reacting to bites. Choose a light-colored fly sheet to reflect heat rather
than absorb it.

When should I put a fly mask on my horse?
Most horses benefit from wearing a fly mask during turnout whenever flies, gnats, or mosquitoes are present, typically from late spring through early fall. Some horses that are particularly sensitive to insects may wear one year-round in warmer climates. Always remove the fly mask at least daily to check for rubs, clean out debris, and inspect the eye area. Never leave a fly mask on a horse that you can't check regularly, and always remove it before putting on a halter or bridle.

What is the difference between a fly sheet and a turnout sheet?
A fly sheet is made from open mesh specifically designed to keep insects off the horse while allowing airflow. It provides minimal warmth and is not waterproof. A turnout sheet (or rain sheet) is made from a waterproof shell to protect the horse from rain and wind; it blocks insects less effectively and will trap heat if used in warm weather. Some combination sheets exist that offer both fly protection and light weather resistance, but in
summer, a dedicated fly sheet is the better choice for insect management.
