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 246.
    Rated 5 out of 5 by from works well even with a sweated horse
    Date published: 2017-04-11
    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 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!

    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: 2016-08-14
    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.

    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 5 out of 5 by from Best fly spray ever I have been using Endure for many years. This stuff really works. Love that it doesn't wash off with the rain. I wouldn't use anything else on my two boys.

    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.
    Date published: 2016-07-26
    Rated 3 out of 5 by from Fly spray Effective at keeping flies from biting for a few hours at best and maybe better than other products. Unfortunately, like most fly sprays, this one also does not live up to it's claim of "protecting" from biting insects for 14 days...maybe only for 14 hrs. if you're lucky!

    Rated 4 out of 5 by from Best fly spray on market I've tried them all and this product works. I'll purchase again.

    Rated 4 out of 5 by from Stays on pretty long! I've been using Endure for about a month in addition to a fly sheet and mask. I've noticed fewer bites on my horses exposed areas! It is definitely sweat resistant but not waterproof. The smell is really strong and not pleasant but it does the job!

    Rated 5 out of 5 by from The BEST This is the most effective fly spray I have tried, hands down. It works fast and stays active even if your horse is sweaty. The sprayer doesn't clog or malfunction and the quart bottles can be refilled numerous times. I buy the gallon size - can't beat the free shipping!!

    Date published: 2016-06-19
    Rated 5 out of 5 by from My only spray I've gone through many fly sprays, and though I usually try to keep things natural I have zero tolerance for flies. At my previous boarding place I couldn't be out more than once a week, and I couldn't ask the barnhands to spray him (hard to catch in a giant pasture...). Every time I came he was being devoured by flies, until I started using Endure. This is the only product that stood up to the test of once a week application. While other horses were getting bit up while riding, mine was relatively unscathed. I'd say about half of the flies that were sprayed directly were instantly knocked down. Added plus: I used this to spray a wasps nest in the horse trailer - Wasps were dead or running and no one built a nest in its place. Sure, that's a little scary, but you know what so is coming to the barn only to see your horse has become half horse - half fly. It is a little expensive, but aren't all fly sprays? I'd rather pay a bit more for one that works, and I am loyal to Endure at this point. Stock up when there are sales and get the gallon refills - I bought two a few years ago and I just ran out this winter. Combined with garlic flakes and fly predators, my horses are looking way better than the others at our barn when it comes to flies.

    Rated 3 out of 5 by from Good product, unfortunate leakage Bought the product to take with me on a travel. Opened the package a week after it came and one of the refill jugs was damaged and had a leak. But happy with the product otherwise :)
