What Customers Say:
OutSmart® Fly Spray is rated 3.9 out of 5 by 826.
Rated 3 out of 5 by from Mixed feelings on this one I really like that this is natural, and I really wanted to love it, but it isn't strong enough for the height of fly season, at least not where my horses live. Of my three horses, one of them coughs EVERY time I use it, one of them tries to run away from it and sneezes constantly when I spray him, and it seems to have no effect on the third one. It might keep the flies away long enough for me to tack them up to ride, but the effectiveness doesn't last long, so I have to keep reapplying and using a lot of the product for it to be useful. Since two of my horses had a negative opinion of it, I can't recommend this to others.

Rated 2 out of 5 by from Still searching for a fly spray that really works Disappointed in the results with this fly spray. Within 30 minutes of spraying my mare the flies started landing on her again. I do LOVE the smell vs the other fly sprays though!

Rated 4 out of 5 by from Love! I have used this product for the last 3 summers & I love it! I have in a pinch used other fly sprays when I ran out & can tell they don't work as well. The peppermint smell is VERY strong, I end up covering my mouth when I use it but it works wonders for my guy!

Rated 1 out of 5 by from All 3 horses had a reaction One horse had a reaction ( mucus discharge) one horse couldn’t tolerate it on his skin and needed to have the fly spray washed off. One horse sneezed a lot.

Rated 3 out of 5 by from Worked on one horse, burned the other This seems to work as well as anything on one of my horses and the smell is definitely better than others. But, when I put it on my other horse, it was clearly burning him almost immediately. He started to shake and went down to roll and roll. I got him up long enough to wash it off and then he was fine again. I tested it on a small section the next day, same reaction. I guess he's sensitive to the active ingredients, so be sure to test this first.

Rated 3 out of 5 by from Holy stink… It smells like peppermint…but on steroids. The smell is so strong that my horse hates it. I can’t really use it on myself either because it gives me a headache. It seems to work for the flies but oh man. It’s hardly usable for the stench.

Rated 1 out of 5 by from Wish it worked I’ve used this product for a few years, mainly when getting ready to ride. I’ve noticed this year that it provides very little deterrence after a few minutes. Maybe our pesky pests are becoming more stubbornly immune.
Date published: 2022-06-11
Rated 3 out of 5 by from Peppermint Scent Is really strong, like my horse and I are both choking and coughing strong. It works as well as any fly spray, in that you’re spraying your horse and hoping it works this time.
Date published: 2022-06-06
Rated 1 out of 5 by from Smells nice and that’s about it May as well use water. I bought 2 bottles and it was a total waste of money. I sprayed my horse down very thoroughly. In the 30 seconds it took to walk him to the pasture the flies were back. I now basically use it as an expensive air freshener to make the barn smell nice. Terrible product.

Rated 1 out of 5 by from Did Not Work I was very disappointed to find that this fly spray did not work on the flies in Southern California. It did not even kill the flies when sprayed directly. They would fly off then come right back a few minutes later.

Rated 1 out of 5 by from Sticky residue, took off horse's hair! I used this for a few weeks in early spring, not entirely sure it was keeping bugs off but happy to try a "natural" product. After small bottle was gone, I ordered a refill jug and used it generously since bug season was now upon us. It left a sticky dark residue on my horse's coat, but I (foolishly) continued to use it, thinking that it was worth it to keep the bugs away. Big mistake!! A patch of sticky residue on her chest actually removed the hair!! I've since bathed her well to get all of it off from her entire body and am hoping (expecting) that the hair will grow back. I wish I could recommend this product, but I do not.

Rated 4 out of 5 by from Works well Keeps the flys away. Pleasent smell. Works as well as any other fly spray I have used.

Rated 5 out of 5 by from This fly spray doesn’t take your breath away when I like it better than other fly sprays I’ve tried.

Rated 5 out of 5 by from Only thing for South Georgia bugs! We live in a very humid area with little breeze, especially during insect season. This fly spray works better than anything we have ever used before! It is strong, so avoid it blowing back in your face, but man, it works for the gnats, flies, and mosquitos! I even put a dab by my ears to keep the bugs away when I am out there. Leaves no oily residue and dirt does not attrack on my white horse.
Date published: 2022-05-13
Rated 5 out of 5 by from Love it This is the third year that I have purchased Outsmart fly spray, and I love it. The bugs are kept away, my horse doesn’t mind the odor and I don’t get a headache from chemicals being sprayed in the air. Win, win!

Rated 4 out of 5 by from Naturally great Smells Great. Does a good job. I'm happy that it's not toxic but it only lasts about 6 hours.

Rated 5 out of 5 by from Best fly spray I’ve ever used ! In order to receive free shipping, i added this flyspray to my cart. I tried it today, not expecting much and lo and behold, the flies immediately disappeared! I’ve never used a more potent flyspray. And my boy even smelled lovely. 100% satisfied with this product.

Rated 5 out of 5 by from Sprayer is great! Works well, crazy flies this year. First time using this product, don’t want chemicals.
Date published: 2021-09-21
Rated 5 out of 5 by from Works Amazingly!!!! I bought this product a week ago and it’s worked better than all the fly sprays I’ve tried. I lease a thoroughbred and she’s sensitive but I works pretty well on her although if she’s already up when I get her from the field she does kind of react to it. It smells like peppermint and it can be really strong especially if it blows back in your face. Overall it’s a really good product and works really well.

Rated 1 out of 5 by from Does not work in my area Spray on the horses and all the flies jumped on me, then back on the horses within minutes.
Date published: 2021-09-07
Rated 5 out of 5 by from Actually works! I have tried many eco/bio fly sprays. This one smells great, the flies were gone and I can use it on myself (haven’t tried that yet)
Date published: 2021-08-30
Rated 3 out of 5 by from Just ok While it did repel insects, it made every horse I put it on cough when applied. They actually would scurry to the other sides of their stalls if they saw the bottle coming, they all hated it. Switched back to Pyranha wipe n spray and they all returned to normal behavior.

Rated 5 out of 5 by from Best ever! I have tried many fly sprays before....this one tops them all.
Date published: 2021-08-25
Rated 2 out of 5 by from Didn't love it :-( Read the reviews and seemed like people either loved the product or didn't love it. I unfortunately didn't care for it. I was looking for a "healthier" spray, but it was very strong smelling and didn't work that well. Also it was more a a full squir application versus a fine mist. My horse didn't care for the odor and the flies were back in no time. Obviously it won't work as well as a pesticide type spray, so not an apple to apple comparison. Wish it had worked. Smartpak was great about their guarantee though and took care of me. As always it shipped fast and arrived on time.
Date published: 2021-08-09
Rated 3 out of 5 by from Smell is too strong and doesn't work I bought two of these, thinking I'd love it, but it was only a quarter of the way through the first bottle before I decided to return the second one. The peppermint smell is nice but it's so strong that it makes me cough and burns my lungs. Flies are right back on my horse after the smell dissipates. I love that it's all natural, but just doesn't get the job done unfortunately!

Rated 5 out of 5 by from Best natural fly spray This is the best all-natural fly spray I have found yet (over fly bye, equisect and pyrhana zero bite). It smells great (minty) and my sensitive horse hasn’t had any reaction to it. Will keep buying
