Do You Need Fly Spray If You’re Using a Fly Rug? The Truth Behind the

As horse owners, we all know how relentless flies can be during the warmer months. They don’t just irritate our horses—they can cause stress, skin reactions, and even transmit diseases. That’s why fly protection is more than just a seasonal convenience; it’s essential care. But with so many products on the market—from fly rugs to fly sprays—many riders ask:
“If I’m using a fly rug, do I still need fly spray?”

Let’s break it down, especially through the lens of one of the most talked-about innovations in equine fly protection: the zebra print fly rug.

What Is a Fly Rug?

A fly rug (also called a fly sheet) is a lightweight, breathable blanket designed to shield horses from biting insects. They’re typically made from fine mesh that protects without overheating the horse. At Cavvalure, we champion elegance and performance—and our upcoming zebra print fly rug is both a style statement and a science-backed solution.

The Science Behind Zebra Print Fly Rugs

Zebra stripes aren’t just fashionable—they’re functional. Numerous studies (including those from the University of Bristol and Lund University in Sweden) suggest that the contrasting black and white stripes of a zebra pattern confuse and deter biting flies like horseflies and stable flies. The stripes interfere with the flies’ ability to land, reducing the chance of bites.

In essence, the zebra print fly rug isn’t just a trend—it’s a strategic deterrent grounded in research.

So, If You’re Using a Zebra Print Fly Rug, Do You Still Need Fly Spray?

The short answer? It depends on your horse and the level of fly pressure in your area. Here’s an in-depth look:

✅ When a Zebra Fly Rug Might Be Enough

Low to moderate fly activity: In areas or seasons where insect pressure is relatively mild, a high-quality zebra print fly rug may provide sufficient protection.
Horses with sensitive skin: Fly sprays sometimes contain chemicals that irritate sensitive horses. A rug offers a gentler solution.
Turnout environments: In open, breezy fields, flies tend to be less dense. A rug alone may do the job.

❌ When You Might Still Need Fly Spray

Even with a zebra print fly rug, fly spray can play an important supporting role:

Leg and face protection: Most fly rugs don’t cover the lower legs or face completely. A fly spray fills in these gaps, especially on the underbelly and ears.
High-fly areas: Farms near woods, water sources, or manure piles tend to have dense fly populations. Fly spray helps reinforce protection.
Rug gaps or movement: No rug stays perfectly in place all day. Spray helps deter flies in those vulnerable areas where the rug might shift.
During exercise or riding: Unless you’re using a fly exercise sheet, your horse may be more exposed. A pre-ride spritz of fly spray keeps them focused and comfortable.

The Ideal Strategy: Rug + Spray

In most cases, the best protection is a combination:
A high-quality zebra print fly rug to act as your horse’s first line of defense, and targeted use of fly spray for exposed areas or high-pressure days.

Bonus Tip: Choose the Right Products

Natural fly sprays: For horses with sensitive skin or for owners preferring a chemical-free solution, citronella or essential oil-based sprays can be effective and gentle.
Durable, breathable rugs: The zebra print is only part of the story. Look for UV protection, anti-rub linings, and secure fastenings.

At Cavvalure, we’re passionate about combining form and function. Our zebra print fly rug is crafted for riders who demand more than just protection—it’s designed for performance, comfort, and striking good looks in the field.

Final Verdict: Fly Rug vs. Fly Spray

A zebra print fly rug can significantly reduce fly landings and bites, thanks to both physical coverage and the science behind its pattern. However, for complete, all-day protection, especially in hot zones or for sensitive horses, fly spray is still recommended.

The real power lies in combining both tools—just as elegance and innovation meet in every Cavvalure design.
