Updated April 5, 2023

With horses, comes flies and the never-ending battle to protect them from bothersome, disease-borne, biting insects. In this article, we’ll give you recommendations for top fly protection products that’ll help you repel pesky flies and biting insects to keep your horse comfortable all summer long.

For a deep dive on the types of insects that might attack your horse and when, along with how to fight flies on every front, visit our guide on fly solutions for horses.

Why Do Flies Fly Around Horse’s Eyes?

Flies are attracted to moisture in your horse’s eyes. We all know flies in your horse’s face can be increasingly irritating for both you and your horse. Flies and insects can potentially be a health risk as they could carry diseases or cause summer sores near the corners of the horse’s eyes (also known as “fly sores”).

Fly masks are designed to protect your horse’s sensitive eyes, nose, and face from biting insects as well as harmful UV exposure. Your horse will be more comfortable during fly season with their face shielded from bugs, dust and debris, and allergens. While some owners may just put a fly mask on their horse for turnout, its also a handy option when riding (especially on the trails) or for protecting an injury on the face. Horses can wear fly masks all day and night, but they should be taken off at least once a day so you can clean your horse’s face and eyes.

Top Protective Wear for Your Horse’s Eyes and Face

There are many different types of fly masks that provide varying amounts of coverage, different materials and linings, and offer innovative designs.

When shopping for a fly mask, it’s important to consider your horse’s unique characteristics and lifestyle. Consider how sensitive or irritable they are towards bugs landing on them – if they twitch and stomp at any little fly, they may do best with a full coverage mask protecting the face, ears, and nose. For coverage, also consider if your horse has sensitive pink skin and could sunburn easily (typically on the muzzle and around the eyes). Plus, your horse may enjoy being rowdy in turnout or be part of a playful herd, in which case he will need a more durable fly mask.
