Questions & Answers

6 Customer Questions

Can this be used on dogs?
Answer by ChewySep 10, 2019
At this time, as an EPA registered pesticide, Ecovet only has authorization for use on horses and cattle. They cannot approve its use on other animals. We have heard reports, however, that when used on other animals there has not been any adverse reaction.

There seems to be some confusion about is this new scent or old scent. What scent is the 18 oz and the gallon?
Answer by ChewyMay 21, 2019
This spray has a natural fragrance of sage and lavender.

Does this spray work well in a Flairosol type spray bottle?
Answer by ChewyJun 06, 2019
This repellent can be applied using any commercially available small sprayer suitable for oil application.

can it be used on lactating donkeys and their foals
Answer by ChewyMay 08, 2022
This spray is intended for use on horses and beef and dairy cattle.

I have spent way too much money on all the fly sprays. The chemical ones work a little better than the natural ones and water based are better in hot sunny areas than oil based, etc etc. Not one on the market really every worked well or for very long. I read about this one and decided to give the small bottle a shot, because there arent many left I havent tried. And like that, they were gone. This stuff stinks and if atomized near your nose, you will regret it. I spray it onto a soft brush and then brush it on the legs and along the body lines, paying attention to the chest, withers, butt and belly. I use much less than other traditional fly sprays. I have had a gallon for three years with 4 horses so it actually costs a LOT LESS. I apply it every day at peak season and every two days other wise. IT WORKS. The flys just disappear and stay disappeared. My horses will wait for me to put it on them. They know the bottle and the brush mean the flies will go away so they stand and wait. Stop waisting your money on anything else. This stuff is magic in a bottle.

Really good flyspray

I like ecovet fly spray because I can use it on both my horses and my dairy cow. It's convenient to only need to buy one product. It works very well on the flies that bite the animals legs. I do not use it on their faces, however.

Works well

If you can past the smell, Ecovet fly spray does the job. It works well on horses that have sensitive skin.

This stuff is amazing

Disclaimer: it doesn't smell great but what fly spray product does This stuff is amazing and works perfectly. It doesn't use harsh chemicals like a normal fly spray. It uses sciencey stuff to actually keep bugs (including those horrible, horrible little midges) from smelling your horse so they don't even recognize her. After I spray this on I do not see any flies land on her at all. It's a godsend.

fly repellent

I tried this product and with all fly products, it works for about 30 seconds. It has a really strong odor which is, i am assuming, what repels the flies but like everything else i have tried, it doesn't last long. i had high hopes for it. i just wonder if everyone else has the same problem. i am so sick of seeing flies on my horses. as for doing orders through chewy, they are quick on getting the orders out and very helpful. not their fault this product isn't great.

My new fly spray

This is my first time using this spray and I learned quickly you do not apply it like you would traditional fly sprays where you and the horse look like you are appearing out of the mist. If you do just that, you will throw the bottle of the nearest trashcan. Also note, just because it is listed as "all natural" doesn't mean you or your horse will not have a reaction. Poison ivy, oak, snake venom are all natural but not safe. Use just a little of this product. Hold the sprayer fairly close to the horse's leg and give gentle squeezes to the sprayer. One spray for lateral side of each leg, one spray for the medial side, one for the belly, top of the tail you can use two sprays and for the long tail hair, too, use a cloth for ears and parts of the face. Avoid eye area and nose area. If you wear contact lenses, heed the warning about not spraying to make a big mist. I learned the hard way! The fragrance/smell people complain about is real but can be lessened with a different application approach. This product was effective for two days! I was lucky to get 30 minutes with the top traditional brands of fly spray. I was looking for something different and I found it. I can't believe I'm rating something so effective with only 4 stars, but it is an irritant to my skin and it does have a peculiar odor. But if you could see my horse grazing only swishing his tail occasionally vs the horses in the paddock adjacent, the difference is remarkable. I will change my methods. Just remember the adage: less is more. Hopefully this will help someone else. I almost threw my bottle away 2 days ago, too, but I saw how well it was working. If you can still smell it on your horse, don't apply more. Not needing to reapply also helped. Now, I'm not riding right now so he hasn't been hosed off. This is not waterproof. We shall see how multiple applications work out by the end of bug season! I am in central Virginia and flies are bad here. My horse is the only one treated with this product and the only one who isn't stomping or swishing. Interesting product but just remember do not use it the way you would a traditional spray. It is completely different and you will be miserable. No misting of the product and you might want to keep using it.

Not your average fly spray!

This is NOT your average a pesticide based fly spray. This is nature based fly repellent. The ingredients in this product are probably some you have never read before on a bottle of fly spray. Instead of using pesticides, this product uses naturally occurring fatty acids made by animals and humans that messes with flies chemical cues to locate us. To flies it makes your horse appear to have an invisibility cloak. This stuff is extremely effective and lasts way longer than a traditional water/pesticide based fly spray and it even beats out oil/pesticide based fly sprays. Now that being said overall - 5 stars. In the pleasant smelling category more like a 1.5 stars. Once you get used to it it’s not so bad; but get a good blast of this in your face and you’re gona be hacking for a minute. It’s not that it smells “bad” (like garbage or sewage) but it’s good at taking your breath away and blocking out you sense of smell for a bit. Once you try it you’ll understand the sensation and you can understand why it’s so good and messing with flies chemical cues! I recommend this for its duration of effectiveness, overall effectiveness and the fact that it’s not a pesticide. A great addition to a more natural horse care routine.

Works well!

I got Ecovet about 10 days ago and am very happy with how well it keeps flies away from my gelding. The smell doesn't bother me, but it does make my horse snort to get it out of his nose, I suspect because it's oily.

Smells horrible, works great

Despite the truly repulsive smell, this is the only product that kept the flies off my horse's summer sore so it could heal. This is an indispensable item to combat flies.

Does not work

I was hoping this fly spray would work. We are very diligent in the flies at our barn. We have predators, fly bags and fly spray daily. The cheapest fly spray I have ever used worked better than this and it is over $100. RIP OFF! It smells terribel which would be fine IF it worked
