The Dirty Secret Behind ‘Trusted’ Fly Sprays That No One in the Industry Wants You to Know

How Thousands of Horse Owners Finally Escaped Ineffective, Toxic Fly Sprays.

"They laughed when I ditched chemical fly spray, but their faces changed when I found the best way to get my mare to stop stomping."

If you’ve ever stood in the aisle of your barn on a hot summer day, shaking yet another bottle of fly spray, you probably know the feeling:

 

Your horse is stomping, tail swishing, tossing his head in frustration. You spray. And spray again. For a few minutes, maybe even an hour, things seem calmer. But then the welts appear, the stomping resumes, and you’re left with the sinking feeling that nothing actually works.

 

It’s exhausting. And it’s expensive.

 

Most horse owners have quietly wondered the same thing: “Are these sprays just bottles of water with a scary label and a strong smell?”

The Hidden Truth About Common Fly Sprays

Here’s what many companies won’t tell you:

 

  • Most mainstream fly sprays rely on harsh chemicals like DEET or synthetic pyrethrins—pesticides linked to skin irritation, respiratory problems, and even long-term health concerns for both horses and humans. Multiple studies, including those published by the National Pesticide Information Center and the U.S. Centers for Disease Control, have documented these risks
     
  • They’re short-lived. Sweat, sun, and humidity break them down fast, meaning you need to reapply every 30–60 minutes. That’s wasted time, wasted money, and constant stress for you and your horse. If you take 5 minutes to look at the reviews left on most fly spray products, this issue is obvious.
     
  • They don’t pass the “barn test.” Ask around: one horse reacts, another doesn’t. Some formulas leave greasy residue, clump dust, or smell so strongly that you cough just being around the animal you love most.

 

In short: horse owners are paying top dollar for products that are toxic, inconsistent, and often ineffective.

On June 13, 2025, the AVMA reported an outbreak of equine infectious anemia (EIA) that killed 21 horses in the Southwest. The virus can spread through biting flies like horseflies and deerflies, putting every horse at risk.

Why Horse Owners Feel Trapped

1. The chemical sprays feel risky and unethical (especially around kids, pregnant riders, dogs, and your own skin).

2. The natural sprays feel safer, but they barely work. So your horse keeps suffering.

3. You’re left feeling guilty, frustrated, and stuck with bottles piling up in the tack room.

After 50 Years of Seeing Horses Suffer, He Decided to Fix It Himself.

How It Started

Tim Cable, a third-generation farrier with over 50 years of hands-on experience, had seen it all. Every season, he and the horses he worked with were exposed to the same toxic, short-lived sprays. Harsh chemical clouds in the barn aisle. Bottles that barely kept flies away for fifteen minutes. Skin irritation for horses. Headaches for humans.

 

Tim knew there had to be a better way. After years and years of trial and error with hundreds of products, he set out to create the solution he wished had existed all along: a fly spray that actually worked for hours, without poisoning the animals and people he cared about.

 

His inspiration? His daughter, Charlee. Just like her dad, she loves horses, and Tim was determined to make a spray safe enough to use around her, yet strong enough to stand up to the toughest barn conditions.

How It's Going

The result was Charlee’s Fly Spray: a long-lasting, all-natural formula that repels flies, gnats, mosquitoes, horseflies, and deer flies for 4+ hours—without the chemical junk. 

 

With its mild, pleasant scent and proven staying power, it quickly became the spray trusted by thousands of horse owners who care as much about safety as they do about results. Tim is so confident you’ll fall in love with Charlee’s Fly Spray, he offers a 100% satisfaction guarantee.

 

Charlee’s Fly Spray wasn’t born in the corporate world for mass production or whipped up by a faceless corporation. It started with one man’s frustration and his family’s safety.

Over 5,000 horse owners say it’s the most effective fly spray they’ve ever used—and it gives the best bang for their buck, since it needs far fewer applications than common sprays. The all-natural ingredients make the results even more impressive.

What Riders Notice First

  • 4+ hours of protection in real barn conditions (heat, sweat, turnout, trail).
     
  • Calmer, more focused horses—less stomping, tail-swishing, head-tossing.
     
  • Safe, plant-based formula you can feel good using around kids, dogs, and you.
    Fewer reapplications = less hassle and better cost per ride.

Why It Works (and Why Other Sprays Don't)

Most sprays trade short bursts of relief for harsh chemicals that irritate skin and lungs—then sweat and sun break them down fast, so you’re re-spraying every 30–60 minutes.

 

Charlee’s uses a plant-powered system designed to bond with hair and coat, so it sticks through sweat and stays effective without the chemical junk. Think “armor without poison”. Practical protection that buys you calmer rides and longer, happier turnout.

With over 20,000 bottles sold nationwide, Charlee’s Fly Spray isn’t just another fly spray—it’s a movement among horse owners. More and more barns are making the switch to safe, plant-based protection that actually works.

What Options Do Horse Owners Have?

  • Loaded with DEET, pyrethrins, and harsh pesticides.
  • Cause skin irritation, coughing in the barn aisle, and long-term health risks for horses, riders, kids, and dogs.
  • And even with all those risks, they barely last 30–60 minutes in heat or sweat.

Option 2: Settle for “Natural” Sprays That Don’t Work

  • Safer ingredients, but almost no staying power.
  • You spray, wait a few minutes, and the stomping and tail-swishing are back.
  • Bottles pile up in the tack room, and frustration piles up with them.

Option 3: Switch to Charlee’s Fly Spray

  • A barn-tested, plant-based formula proven to keep flies, gnats, mosquitoes, and horseflies off for 4+ hours.
  • Safe enough to use around kids and dogs, gentle on sensitive horses, and trusted by Olympic riders to therapeutic barns.
  • Backed by a 100% satisfaction guarantee. If you don’t love it, you don’t pay.
