The Natural Way to Protect Your Horse – Diatomaceous Earth & Fly Control

August 19, 2025

🐴 Introduction: The Summer Struggle Is Real (But Fixable)

You’ve tried the fly sprays. You’ve mucked out daily. You’ve stuck to your worming schedule.
But no matter what you do, your horse is still stomping, swishing, and rubbing all summer long.

The flies won’t quit. The worm count never seems to drop. And you’re wondering if there’s something you’re missing.

If that sounds familiar, you're not alone.

Many horse owners are starting to question whether the usual cycle of chemical wormers and emergency fly sprays is really enough. You want a more natural, effective way to protect your horse — something that works from the inside out, not just a quick fix.

That’s where Diatomaceous Earth comes in. It’s not just a trendy supplement. It’s a time-tested, natural solution that supports parasite control, gut health, condition, and more — and when used alongside smart stable hygiene and targeted fly protection, it can transform your yard this summer.

In this article, you’ll learn:

How Diatomaceous Earth works inside your horse’s gut to fight parasites
The surprising extra benefits — from coat condition to lactation support
Why disinfecting your stable is more important than you think
The fly control products that actually make a difference
How to build a simple, natural daily routine for a calmer, healthier horse

Let’s break the cycle — and finally get ahead of the flies.

🐚 What is Diatomaceous Earth and How It Works

Diatomaceous Earth (or DE for short) might sound like something out of a science lab, but it’s actually a natural substance made from fossilised remains of microscopic algae called diatoms. The result? A soft, powdery substance that feels like talc but acts like a gentle, natural armour against internal and external pests.

When fed to horses, food-grade Diatomaceous Earth moves through the digestive system without being absorbed into the bloodstream. Instead, it works mechanically — the microscopic, silica-rich particles have sharp edges that help break down the waxy coating of parasites and worms. This dehydrates them and causes them to die off, without using any chemicals.

It’s a simple but powerful approach:

No harsh chemicals
No resistance build-up
Safe for daily use when dosed correctly

And because DE doesn’t work like a traditional wormer, parasites can’t adapt to it. That makes it a brilliant long-term support tool alongside regular worm counts and vet-advised worming schedules.

👉 Hint: Make sure you’re using food-grade Diatomaceous Earth — not the kind used in filtration or industrial settings. We stock DE that’s specifically safe for horses, including our natural salt lick blocks that combine mineral support with daily DE intake.

💪 The Benefits of Diatomaceous Earth for Horses

You already know Diatomaceous Earth helps control parasites — but its benefits don’t stop there. When used consistently as part of your horse’s diet, DE can support their overall health in some seriously underrated ways.

Here’s how it helps beyond worm control:

1. Improves Condition and Coat Health

DE is naturally high in silica, a trace mineral that supports healthy skin, coat, hooves, and connective tissue. Many horse owners report shinier coats, stronger hooves, and better topline condition after adding DE to their feeding routine — especially in horses prone to dullness or itching during fly season.

2. Supports Healthy Weight Gain

Because DE promotes a healthier gut environment and reduces the parasite load, horses may absorb nutrients from their feed more efficiently. Over time, this can lead to better weight maintenance or gentle weight gain — especially helpful for hard keepers or older horses.

3. Fertility and Lactation Support

In broodmares, DE can support:

Fertility by contributing to better overall condition and mineral balance
Lactation by helping the mare maintain weight and nutrient absorption during demanding times

It’s not a magic fix, but as part of a broader nutritional strategy, DE can help mares feel stronger, healthier, and more resilient.

4. Digestive Cleanse and Toxin Removal

DE also acts as a natural detoxifier. It can help remove heavy metals, toxins, and undigested matter from the gut — which can reduce bloating, gas, and general discomfort. Many owners report horses being more comfortable, calmer, and less prone to digestive upset.

👉 Looking to try it out? We stock high-quality, food-grade Diatomaceous Earth that’s safe for horses, as well as natural salt lick blocks containing DE for convenient, daily access.

🪰 Can Diatomaceous Earth Help With Fly Control Too?

It might seem odd to connect a feed supplement with fewer flies — but when you understand the fly life cycle, it actually makes perfect sense.

Flies are drawn to manure. It’s where they lay their eggs, and where larvae hatch and develop. The more parasites and undigested material in the manure, the more appealing it is to flies. That’s why a gut full of worms or a sluggish digestive system can actually contribute to fly overload.

By supporting your horse’s digestive health and reducing internal parasites, Diatomaceous Earth helps in two big ways:

1. Cleaner Manure = Fewer Fly Breeding Grounds

DE helps kill off internal parasites and improves digestion, meaning the manure your horse produces is:

Less parasite-laden
Less acidic
Less appealing to flies

Fewer parasites in the gut = fewer parasites in the manure = fewer flies buzzing around your yard.

2. Healthier Horses Are Less Attractive to Flies

Flies are naturally drawn to irritated skin, wounds, or sweating caused by poor condition or gut issues. Supporting your horse’s health from the inside out can make them less of a target for biting insects in general.

So while DE isn’t a replacement for good yard hygiene or topical sprays, it’s a powerful first layer of defence in your fly control strategy.

Next up:
“Why Disinfecting the Yard Matters” – where we’ll talk about your Stable Yard Wash, how it breaks the fly and parasite cycle, and why it's crucial to your overall plan.

🧼 Why Disinfecting the Yard Matters More Than You Think

Even if your horse is healthy and your feeding routine is on point, a dirty yard can undo all your hard work.

Flies, worms, and bacteria don’t just live in your horse — they thrive in the environment around them. Damp bedding, leftover feed, and soiled corners of the stable are prime breeding grounds for fly eggs, worm larvae, and disease-causing bacteria.

That’s why regular disinfection is non-negotiable — especially in warmer months when parasites explode in numbers.

Here’s what’s really going on in your stable:

Flies lay eggs in damp, organic matter like manure or bedding
Worm eggs and larvae are shed in manure and can reinfect horses
Bacteria and fungi build up in corners, feeders, and water troughs

If you don’t break the cycle at the environmental level, it just keeps repeating.

Enter: Your Stable Yard Wash

This isn’t just any cleaner — it’s a targeted disinfectant that kills bacteria, fly eggs, and parasitic larvae on contact. It helps you:

Break the parasite life cycle before it restarts
Create a safer, cleaner living space
Cut down fly populations at the source

Used regularly, it’s one of the most effective ways to keep your yard — and your horses — healthier all season long.

👉 Top tip: Pair your DE feeding routine with weekly stable disinfecting to tackle parasites and flies from both angles.

Next up is:
“Daily Fly Control for the Yard” – where we’ll talk about your Stable Yard Spray and how it keeps fly numbers down day-to-day.

🚿 Daily Fly Control for the Yard

Disinfecting once a week is essential — but flies don’t wait for your schedule. They breed fast and come back even faster. That’s why daily fly control around the yard is just as important as managing your horse’s diet and stable hygiene.

Even with the cleanest mucking-out routine, you’ll still have to deal with:

Flies landing on walls, doors, and bedding
Fly eggs laid in hidden or hard-to-reach spots
New flies entering from nearby fields or yards

That’s where your Stable Yard Spray comes in.

Think of it as your invisible fly fence

Designed for daily use, your yard spray helps to:

Repel and kill adult flies around stables, doors, walls, and fences
Deter flies from laying new eggs in treated areas
Create a less hospitable environment for flying pests in general

You can use it:

Along stable walls and door frames
Around muck heaps and feed rooms
In open barns and shelters
Even on wheelbarrows, bins, and tack room entries

And because it’s designed for daily use, it’s safe enough to apply regularly without overwhelming scents or harsh chemicals.

🧪 Pro tip: Your Stable Yard Spray works best when used in combination with regular disinfection (like your Stable Yard Wash) and internal support (like DE). It’s all about layers of protection.

Next section:
“Protecting the Horse: Sprays & Masks” – where we’ll bring the focus back to the horse and explain how your Horse Fly Shield Sprays and Fly Masks round out the plan.

🐴 Protecting the Horse: Fly Sprays & Masks

You’ve cleaned the yard. You’ve treated the environment. You’re feeding Diatomaceous Earth. But to truly shield your horse from the non-stop annoyance (and risk) of flies, you need to add one final layer: direct protection.

Flies don’t just irritate — they cause stress, spread bacteria, and can even lead to infections around the eyes, ears, and wounds. For sensitive horses or those with allergies, fly season can be miserable without proper protection.

Here’s how to keep them comfortable and safe:

1. Horse Fly Shield Sprays

These sprays are your horse’s personal barrier against biting insects. Your Fly Shield Spray helps to:

Repel flies, midges, horseflies, and other pests
Soothe irritated skin with gentle ingredients
Provide long-lasting coverage without stickiness or strong smells

Best applied before turnout, schooling, or hacking — and especially useful around sensitive areas like the belly, legs, and ears.

🧴 Top tip: Reapply during heavy fly days or after sweating/exercise for maximum protection.

2. Fly Masks: Essential, Not Optional

A good fly mask is one of the simplest and most effective tools for fly control. It:

Protects the eyes from flies, dust, and UV rays
Prevents rubbing, weeping, and secondary infections
Helps reduce head shaking and general irritation

If your horse is out in the field, a fly mask should be part of their daily kit — just like a rug in winter. Choose one with breathable mesh, secure fit, and good visibility.

🛡️ Layering your fly mask with DE in the diet, clean stables, and a spray routine gives your horse 360° defence.
