As riders and online shoppers, we know it can be tough to buy a new bridle or pair of boots without trying them on. That's why we moved the fitting room to your living room (or barn)! From breeches to blankets, if you or your horse can try it on, you can return it, free! Just use the pre-paid return label included in your order within 60 days from the purchase date. And of course, please make sure the item is in like-new condition with original packaging (we said 'fitting room', not 'war room'!).

Instructions for Use:
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.

Not for use on horses intended for human consumption. Shake well before using. To protect horses from horse flies, house flies, stable flies, face flies, horn flies, deer flies, gnats, mosquitoes, lice, ticks, and deer ticks that may transmit Lyme Disease: Thoroughly brush the horse’s coat prior to application to remove loose dirt and debris. For dirty horses, shampoo and rinse thoroughly. Wait until coat is completely dry before applying ENDURE® SWEAT-RESISTANT FLY SPRAY FOR HORSES. Its unique water resistant formula contains a special conditioner that binds to the hair shaft so it keeps working even in moist conditions or when the horse sweats.

This product may be applied either as a spray or as a wipe. For horse’s face, always apply as a wipe using a piece of clean, absorbent cloth, toweling (Turkish) or sponge. Wear rubber glove or mitt when applying as a wipe. Spray or wipe horse’s entire body while brushing against the lay of the coat to ensure adequate coverage. Avoid getting spray into horse’s eyes, nose or mouth.

Application should be liberal for best results. Reapply every 5 to 7 days under normal conditions for initial applications. As protection builds, reapply every 10 to 14 days as needed. Also, reapply each time animal is washed or exposed to heavy rain.

    Endure Sweat Resistant Fly Spray is rated 4.6 out of 5 by 268.
    Rated 5 out of 5 by from Best flyspray! We started using this fly spray last year. Most fly's ignore fly sprays. This one actually seems to work. It doesn't have an obnoxious odor to it either. It also comes in an easy to pour gallon size refill. We will continue to buy this product for fly control on our horses. We have an older grey horse and I sprayed 2 legs with this and 2 legs with another product. At the end of the day the 2 legs with the other product had blood spots from the flies and the legs with this product did not. I marked as an excellent value because it works. There are cheaper products out there but if they don't work it's not a deal.

    Rated 5 out of 5 by from Great Product! I bought this fly spray because I felt my regular fly spray was no longer effective in keeping the flies away from my horses for more than a few hours! Endure Sweat Resistant Fly Spray is working great and meets all of my expectations!

    Rated 4 out of 5 by from Best spray for the money e have been using Endure at our barn for several years. Smartpak definitely has the best price for large amounts (we buy by the gallon) And one of our gallons arrived broken, spilling all contents onto the foyer floor, Smartpak issued a full refund(credit)

    Rated 3 out of 5 by from Use once every 5 days? After using this for 2 summers someone pointed out to me that the instructions say to use it once every 5 days. It works better than anything for the first 8 hours but if I had to wait 5 days to spray my horse again, he would go mad with the flies!

    Rated 3 out of 5 by from Worked for about 10 Minutes I got this hoping it would last longer than the usual stuff I purchase. I feel it performed worse than my usual fly spray. I usually use Fiebings 44. I dont know if others have success with it it with their horses.

    Rated 5 out of 5 by from Say goodbye to ticks and biting flies This is my second season with Endure and I can't believe what a great job it does on my two geldings who are on turnout 24/7. No ticks (and we live in a heavy tick region), minimal biting flies and quiet happy horses. In the past, I've had problems with biting flies stressing out my older gelding but not since switching to Endure. I'll never bargain shot for fly spray again.

    Rated 4 out of 5 by from Only thing that works in the southeast I have used Endure for years. Every time I try to change to something else - I just come back. The bugs (of all sorts) are pretty bad in the south east US and for a pretty long part of the year. No other spray has given me results as good as Endure. There will still be some flies on my horses - but less with Endure than any other spray. It claims to last up to 14 days. I find that it does 'build up' pretty nicely - but no way in my part of the world can any spray last 14 days. I usually have to spray daily - maybe every other day sometimes. I don't need this in the winter - but use it spring/summer/fall. If it did last longer I'd give is 5 stars. It is the best thing out there so far.

    Rated 5 out of 5 by from Works great We brought this last month after using a different brand for quite awhile and it seemed to work better at keeping flys away! Will continue to switch between two brands!

    Rated 4 out of 5 by from Easy Pour Bottle Endure is a marvelous fly repellent. I have used it for years. The new easy pour bottle, however, is NOT an improvement. My gallon bottles of Endure arrived covered in repellent and sitting in puddles of repellent in their plastic bags. Fully a cup of repellent had leaked out. I will not purchase Endure in the easy pkur bottle again.

    Rated 5 out of 5 by from works well have purchased in the past from other sources. Best price here and delivery makes it very easy. Product does what it claims and that makes it different from other sprays.

    Rated 5 out of 5 by from Love this Stuff I have have used Endure for several years now. It's the only spray that works on my horses. As soon as you spray the flies, they fall dead! And it keeps working for several days. I buy a gallon every summer for my three horses! Highly recommend!
    Date published: 2017-04-18
    Rated 5 out of 5 by from Favorite Fly Spray because it works! I have used Endure for several years now. Our pony has reacted to some other brands that we tried and the vet recommended Endure as one that is well tolerated by sensitive skinned horses. I apply a generous amount as directed by the instructions and any flies that light on her after spraying, immediately fly off. Endure works incredibly well and I can ride or play with her without having to worry about flies biting her. I really love how well this product works and the fact that our pony can tolerate it. I often recommend it to other horse owners.

    Rated 5 out of 5 by from The only Fly Spray I use! This is the only spray I use because it is the only one I have found that truly works!! I am so happy I can order it by the gallon on SMARTPAK :)
    Date published: 2016-09-29
    Rated 5 out of 5 by from It really does stay on My friend and I were skeptical when it states "sweat resistant" but it really is. This fly spray lasts longer than any I've ever tried. I was really nervous the first time I took the sweaty saddle pad off and didn't reapply fly spray. Next day, still no flies. Highly recommend!
    Date published: 2016-09-28
    Rated 4 out of 5 by from Smells bad but it works This is the only fly spray I've found so far that actually works. Its got an awful chemical smell and I don't like to use it everyday, but I do use it most days on the parts not covered by the fly sheet since I'd rather take the chance with chemicals than pigeon fever or summer sores. Just bought another gallon of it. I'd give it 5 stars if not for the smell.
    Date published: 2016-09-12
    Rated 5 out of 5 by from Always my favorite! Been using this for years, leaves coat soft, smells great, and best of all really works!
    Date published: 2016-08-14
    Rated 5 out of 5 by from It works I finally tried a new fly spray, Endure. I was as afraid to because my Kentucky Mountain Saddle Horse has such sensitive skin, but now I am so glad I did. One application in the a.m. lasts until the next morning. No more constant stomping and swishing! Dirt does stick to the residue but brushes right off. It is also important to keep out of eyes and off the sensitive skin around the eyes. We use fly masks so this is not an issue.
    Date published: 2016-08-11
    Rated 5 out of 5 by from Best Fly Spray!! I have been using this fly spray for many years. I have tried many others and ALWAYS come back to ENDURE. I ordered the gallon this time because it is cheaper that way and I won't have to buy more this summer.

    Rated 4 out of 5 by from Smells good, sweat resistant At least for normal weather (right now we're at 70% humidity). Good for sensitive skin, keeps the fly attacks down.
