How to Make Fly Spray for Horses: Easy DIY Recipe

The summer heat brings buzzing flies that drive horses mad, their tails flicking wildly as they stomp in frustration. If you’ve ever watched your horse suffer through fly season, you know commercial sprays can be costly or filled with harsh chemicals—which is why making your own effective, natural fly spray for horses is a game-changer. Not only is it gentle on their skin, but it’s also customizable and budget-friendly. Here’s how to whip up a simple DIY version that keeps pests at bay.

Why Make Your Own Fly Spray?

Commercial fly sprays often contain synthetic ingredients like permethrin or pyrethroids, which can irritate sensitive skin or cause adverse reactions. A DIY fly spray for horses lets you control what goes into it—no hidden chemicals, just natural repellents that work. Plus, homemade versions often cost a fraction of store-bought options. Think of it like cooking a meal from scratch: you know every ingredient, and it’s tailored to your horse’s needs. 🐴

Benefits of Natural Ingredients

Essential oils like citronella, eucalyptus, and lavender are nature’s pest deterrents. They’re effective, aromatic, and safe when diluted properly. Unlike synthetic sprays, they don’t leave a sticky residue or overwhelm your horse’s senses. White vinegar, a common base for DIY sprays, balances skin pH while repelling flies—bonus points for its antiseptic properties.

DIY Fly Spray Recipe for Horses

Here’s a basic, effective recipe you can customize based on what’s in your cupboard:

• 2 cups apple cider vinegar or white vinegar – the base that repels flies and soothes skin.
• 1 cup water – helps dilute the acidity.
• 30-40 drops of essential oils – try a mix of citronella, eucalyptus, and peppermint.
• 2 tbsp non-toxic dish soap (optional) – helps the spray stick to the coat.

Combine all ingredients in a spray bottle, shake well, and apply liberally to your horse’s coat (avoiding eyes and open wounds). Shake before each use—essential oils can separate over time. For extra potency, add a few tablespoons of neem oil, a natural insecticide. Test a small patch first to ensure no skin reactions.

Pro Tips for Maximum Effectiveness

Flies are persistent, but these tricks make your spray work harder:

• Reapply often – Natural sprays wear off faster than chemical ones, especially after sweating or rain.
• Spray strategically – Focus on legs, belly, and neck where flies love to bite.
• Store properly – Keep the spray in a cool, dark place to preserve the oils’ potency.

Alternative Ingredients to Try

Out of eucalyptus? Swap in tea tree oil or lemongrass for similar repellent effects. If your horse dislikes vinegar’s scent, use witch hazel or vodka as a base—it evaporates quicker but still carries the oils effectively.

Safety Considerations

Not all essential oils are horse-safe. Avoid pennyroyal, clove, or tea tree in high concentrations, as they can be toxic. Always patch-test and watch for itching or irritation. If your horse has a history of sensitivity, consult your vet before trying new ingredients. Remember: less is more with essential oils—overdoing it can backfire.

When to Use Fly Spray (And When to Skip It)

Avoid spraying directly on wounds, near eyes, or right before riding (some oils can irritate human skin too). For severely fly-prone areas, layer other defenses: fly masks, mesh sheets, and manure management. A homemade spray isn’t a cure-all, but it’s a fantastic first line of defense.

Watching your horse gallop freely without incessant tail-swishing? That’s the joy of a good fly spray. With this simple recipe, you’re not just mixing ingredients—you’re giving your equine buddy comfort without compromise. And honestly, isn’t that what every horse deserves? 🌿
