Ecovet Horse Fly Repellent Spray, 4 oz. Travel size

Pros: it works great to keep regular flies, mosquitoes, and no-see-ums off your horse and anything it touches. Cons: It smells FOUL. My horse coughs and sneezes, it triggers asthma attacks in everyone around you, it lingers around the barn... It also attracts horseflies.

I've been using this spray for at least three years now, and nothing else compares. It works completely different than most fly sprays, as it uses fatty acids to make your horse unattractive to biting insects. Those fatty acids are harmless but can make you and your horse sneeze when you first apply it (I've never had any long term negative effects). It doesn't irritate my horse's very sensitive skin, and a little goes a long way! It is the only thing I've ever seen actually repel the terrible springtime gnats up here in New England. It definitely works better the longer you use it, as the flies learn to just avoid your horse all together after a while. As long as I'm not bathing my horse a lot, etc, I only need to put it on like twice a week, which makes it last longer. (I recommend putting it on legs, underbelly, chest, and just behind the ears.) I keep a different "natural" type spray around as a backup, or for added protection when I'm going to trail ride, or it's a particularly buggy day. I don't buy sprays for how they smell, good smelling ones can be nice, but effectiveness is my priority, and this one is very effective.

This is the only fly spray I'll buy anymore, because although it is expensive per ounce, it actually WORKS, and a little goes a long way. In fact, the strong odor will make you use it sparingly. I stand upwind and spray it on my guy's legs and rump, well away from his nose/mouth (to shield him from the smell). It keeps the flies at bay far longer without reapplication than any other fly spray I've tried. Keep converting folks at my barn, too. Try it, you'll like it!

This is the best fly spray around- don't get it into your eyes, mouth, or nose. The organic acids burn mucous membranes but really do the trick creating a cloud of protection around your horse! A little goes a looooooong way. Bottle is pretty small and goes quickly if you over-spray

Holy canoli Batman, this fly spray's scent is STRONG. And not in a good way. While the new scent does smell better than the original, it is not for the faint of heart. I could hear the flies begging for mercy as I sprayed them off my poor mule's legs. Then, my mule begged for mercy as the fumes engulfed us as well. I managed to get some mist in my eye (I've never done that before with fly spray) and it stung like a thousand angry yellow jackets. As my mule and I exited the gas chamber I accidently created, we both gulped in fresh air in relief. Okay, I may be a little dramatic but for reals though, use this stuff OUTSIDE and make sure there isn't any wind! Even well ventalited barns aren't sufficient. I now tie to the trailer in the open when I use this stuff and even kinda avoid that area for awhile. But, it's totally worth it. My mule was getting absolutely eaten alive by flies earlier this spring and this was the only stuff that would get them off her legs and keep them away. It's been a real game changer for us and the new scent is at least tolerable. I had a bottle a year or so ago that I used once and had to get rid of. Overall, it is worth it, so long as you have a sufficiently ventilated area in which to use it.
