The Pros and Cons of Fly Sheets vs. Fly Sprays: When to Use Each

Custom Mid-Weight Fly Scrim SheetAs temperatures rise and flies return in full force, horse owners everywhere are reaching for their go-to bug defense. Two of the most popular options are fly sprays and fly sheets, but which one is right for your horse? While both offer protection, they work in very different ways. Understanding the pros and cons of each can help you decide what works best for your routine, your horse, and your summer conditions.

Fly Sheets: Long-Lasting, Full-Body Coverage

Fly sheets act as a physical barrier between your horse and biting insects. They’re designed to cover most of the body with breathable mesh fabric that helps prevent flies from landing and biting.

The pros?

They provide consistent protection throughout the day without the need for reapplication. A good fly sheet also shields against harmful UV rays, helping protect your horse’s coat and skin. For horses that are particularly sensitive to fly bites or prone to skin reactions, fly sheets can be a game changer.

The downside?

If the sheet isn’t fitted properly, it can shift, rub, or cause discomfort. And while today’s fly sheets are much more breathable than they used to be, some horses may still overheat in very humid conditions or during intense activity. Not all horses enjoy wearing full-body gear, especially if they’re not accustomed to it.

Fly Sprays: Quick and Convenient

Fly sprays are often the first line of defense for riders on the go. They’re easy to apply, take only a few seconds, and are great for touch-ups before riding or turnout.

Why riders love them

They’re perfect for short-term protection and can easily target trouble spots like legs, faces, and ears. Many also come with added coat conditioners or sun protection, giving you a little extra value in one bottle.

There are drawbacks

Sweat, rain, or rolling in the dirt can quickly make sprays ineffective, meaning they often need to be reapplied multiple times a day. Over time, that can become expensive and inconvenient. And for horses with sensitive skin, certain ingredients may cause irritation.

Which Is Better?

The truth is—they work best together. For all-day protection, especially during turnout or trail rides, fly sheets provide reliable coverage without constant maintenance. Fly spray works well as a backup or for quick outings when a full sheet isn’t practical. Combining both gives your horse the best of both worlds.

If your horse spends a lot of time outside or tends to be a magnet for flies, a well-fitting fly sheet can make a huge difference in their comfort and mood.
