The best fly rugs for keeping your horse comfortable – Summer 2025

As we all know, the arrival of warmer weather brings not only sunshine and longer rides, but also an unwelcome nuisance – flies! From midges and horseflies to biting black flies, these pests seem to make a beeline for our four-legged friends. But why are horses such a magnet for flies in the first place?

Flies just can’t seem to resist horses, and for good reason. Horses give off heat, moisture, and natural scents that are like a magnet for these little pests, especially if there are any scrapes or open wounds involved. It’s not just annoying either; all that buzzing and biting can really stress your horse out, cause skin irritation, and even spread nasty diseases. Definitely not what you want during the sunny season...

Why do horse rugs help?  

Fly rugs (or fly sheets, as they’re sometimes called) are a super easy and effective way to keep your horse comfy during the warmer months. They work like a physical shield, stopping annoying flies from landingt. And these days, they’re more than just bug blockers! Many come with bonus features like UV protection and waterproof panels to handle those surprise summer showers. Pair a fly rug with a good repellent or supplement, and you’ve got yourself a winning combo!

It’s the ideal option for unpredictable British summers, all at a reasonable price point.
