Ecovet: Before and After


This fly season, stop spraying toxic pesticides and start spraying the only pesticide-free solution that works and even helps improve insect-related skin sensitivity.

Ecovet is a totally different type of fly spray for horses - it is not a pyrethrin/pyrethroid derivative (which can be toxic), or an essential oil product.

Instead, Ecovet is the first fatty-acid fly repellent for horses, and it now has an updated scent: an herbal blend of lavender with a hint of tea.

New Scent Is Here!

Just in time for another dreaded fly season, Ecovet fly repellent for horses now has an improved scent based on customer feedback.

Ecovet founder and veterinarian Dr. Tim John describes the new fragrance as an "herbal blend of lavender with a hint of tea."


A totally different type of fly spray, Ecovet is not a pyrethrin/pyrethroid derivative, nor is it an essential oil product. Instead, Ecovet's formulation is 5% each of three different food-grade fatty acids, 84% volatile silicone oil and 1% fragrance. After Ecovet is applied, the three fatty acids evaporate at different rates and create a vapor barrier around the horse. This barrier prevents insects from locating the horse as a potential victim by confusing and overwhelming the bugs' normal directional ability, their "GPS." 

"For our new fragrance formulation, the challenge was to find something that blends nicely with the inherently musky scent of natural fatty acids. We tested many things, but we believe this new herbal blend is a game changer!" explains Dr. John.

The new scent does not impact Ecovet's well-known effectiveness in the battle against flies. 

Ecovet protects horses from flies, gnats, mosquitoes, ticks and lice. Ecovet also improves insect-related skin sensitivity by stopping bugs from finding and landing on horses in the first place. "If a horse isn't bitten, there's less chance for hypersensitivity, aka the dreaded sweet itch," says Dr. John.

An EPA-registered product, Ecovet comes in an 18-oz. bottle and 1-gal. refill, as well as a travel size. Horse owners can look for Ecovet containers with gold "new scent" labels to try the updated fragrance.


Here's a Fly We Actually Like!

Many thanks to Mina for sharing her experience using Ecovet on her aptly named gelding, Fly:


"[I]t's the best fly spray I've ever used! Not a single thing touches my gelding. He's so sensitive to bugs I have a hard time riding him because he's so busy trying to swat flies that he can't pay attention.

"I've tried everything there is and nothing seems to work. I used your fly spray while riding and he's a completely different horse. I've had the best rides all spring/summer on him since switching to your fly spray. He's calm and attentive. He used to run the gate in the field to come in he was so bothered. Not anymore. He's content to graze all day! Everyone at my barn is impressed."

How to Apply Ecovet

Ecovet is an entirely different kind of fly spray – and you also apply it in a different way. To help you and your horse make the flies get lost, we created the video below:


With traditional fly products, you spray until the horse is soaked. Ecovet is different. With our new solution, less is more. Ecovet is long-lasting, so you'll typically only need to apply it every one to three days.

Because Ecovet is so effective and you use less per application than you do with traditional sprays, your trusty bottle of Ecovet goes a looooong way. 

  • To apply Ecovet, you spray the horse's legs, tummy and a little on the top of the head. Apply with care around the eyes and ears.
  • You also want to spray with the bottle closer to the horse's body. This creates less fine mist, which can sometimes be annoying for your horse.
  • Apply outdoors or in an open aisle-way – it can be a strong scent in a closed space. To avoid spraying yourself, stand upwind when applying outdoors. You can also use a soft cloth or mitt.
  • Ecovet works best on dry horses, so don't use it on a just-washed or super-sweaty horse.
