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'!).

    UltraShield Red Fly Spray is rated 4.1 out of 5 by 31.
    Rated 1 out of 5 by from Disappointed So far, it has not worked as well as other products. It almost does not seem to be working at all! I know this is a rough time of year for fly control in NJ, but I am disappointed in the performance of this product.

    Rated 5 out of 5 by from Works for Me I bought this about a month ago and it has improved my riding time. It works better than all the other fly sprays I have tried over the years. Super easy to dispense, too.

    Rated 4 out of 5 by from works pretty well I bought this since it was the least expensive fly product with Cypermethrin. It works pretty well. I board in Florida and it is wet and hot all of July and August. It's a pretty horse dense area as well so I really have never found a miracle fly product. I do think I like Tri Tec 14 a little better.

    Rated 5 out of 5 by from smells good too!!! We all know how poorly fly spray usually works for our equine friends.This one really works for me and even worked through the awful humid Brooklyn weather. I did not see any bloody marks on his lower legs if I sprayed with Ultra Shield Red Fly Spray.Another amazing thing I noticed is the pleasant smell! Hope it continues to work!!! I already bought more.

    Rated 5 out of 5 by from Best fly spray available Love this fly spray, not a horrible smell and it seems to work as good as anything on the market.

    Rated 5 out of 5 by from The best Fly Spray! Started using this product as it was recommended by our fly predator company. It works so much better than all the rest we've used over the years. I particularly like that fact that it is not oily like so many of the other products, thus keeps the coats cleaner on our it's smells really nice!

    Rated 5 out of 5 by from Great for night turnout or while training US red offers great protection for my horses that are on night turnout in the summertime. Offers great protection without an intense smell.

    Rated 1 out of 5 by from Doesn't work It's like spraying water on my horse. Didn't help with bugs one bit. May work better in early spring or fall but in the heart of bug season it doesn't work. My horse was so miserable I had to end my ride early and ended up buying different spray.

    Rated 3 out of 5 by from Used to be my favorite fly spray…. Last year this was the best fly spray I found - worked really well. Sadly this year, not so much. Have to spray often as this doesn't last. Disappointing!

    Rated 5 out of 5 by from Great Fly Spray I purchased just when the flies started to appear. I works great.
    Date published: 2016-02-23
    Rated 5 out of 5 by from Better than most sprays I've used this fly spray for a few years now. I feel it works about as well as Endure, Tri-Tec and Ultra Shield EX. This fly spray is always in my arsenal in the war against flies. A bit more expensive, but you pay for what works.
    Date published: 2015-08-20
    Rated 4 out of 5 by from Effective Product with a Pleasant Scent While Endure is actually my favorite fly spray brand, the Ultra Shield products come in a close second for effectiveness. I often like to combine the two products by spraying one on the horse's body and the other on the legs and belly. Perhaps something about the combination of the two seems to repel bugs better on the really hot/humid days. I like how the Ultra Shield Red Fly Spray smells, and I love the bright red bottle. Its easy to find when digging through a dark trailer tack compartment or tack trunk!

    Rated 4 out of 5 by from Works the best of everything I have tryed for my very fly sensitive horse

    Rated 1 out of 5 by from WARNING: Dangerous Allergic Reaction can Occur I sprayed my horse with this and 24 hrs later he had minor hives, gave benadryl and they went away. A few days later used it again and 24 hours later he had hives so bad his nostrils swelled shut, he almost dies. A vet visit and 5 shots later he was ok. But not worth the risk. We use the Black Bottle of Ultra Shield with no issues, but the Tetramethrin or Cypermethrin in this formula was almost deadly for my boy. Be very careful and watch your horse closely for days after using ANY new fly spray. Switched back to the Black Bottle and no issues at all. Now I use mostly home made sprays. Wish I had taken a pic to show you, but in the moment was not thinking of that.

    Rated 4 out of 5 by from Fly Free Riding! UltraShield Red gives my boys several hours of relief from pests. Works well for various biting flies and mosquitoes but doesn't always deter the huge late summer horse flies. It has a pleasant scent and doesn't irritate their skin.
    Date published: 2014-09-26
    Rated 5 out of 5 by from ultra shield red What can I say, flies have been very bad this summer unable to ride without constant fly attacks. Tried the ultra shield Red my horses and I can enjoy riding again this product actually works.

    Rated 5 out of 5 by from Great protection, swamp bugs don't stand a chance We live in the woods with a bay next to the pasture. Swamp bugs are like nothing you will ever experience! This product works for them like magic as well as on myself when I ride. Not another product out there can touch it
    Date published: 2014-05-19
    Rated 3 out of 5 by from Not worth the $ I gave this spray a try as my long time favorite Repel-X was not keeping flies off as well as in the past. This Ultrashield Red was more expensive, and did no better job with the flies. It smells like citronella and did not last long at all. Just an average spray. Going back to Repel X.

    Rated 4 out of 5 by from From the test zone I live on the coast of Maine where we breed every flying, blood-sucking insect on the planet. We feature, in order of appearance, black-flies, fresh and salt-water mosquitoes, greenheads, deer flies, moose-flies (aka cow flies) and biting stable flies and that's just May-July. I don't know how many varieties of ticks we have, but I'm focusing on the winged critters at the moment. My horse was born without a tail, so he's at a major disadvantage in the fly-swatting department. Just started using this product and I have to say, it seems to be doing a bang-up job.
    Date published: 2013-07-05
    Rated 5 out of 5 by from Good stuff I do like this fly spray. I use the ultra shield in the black bottle for summer months when flies are really bad. But then I buy this for the non summer months. It's a few dollars cheaper but does the trick.
    Date published: 2013-01-16
    Rated 5 out of 5 by from Very Nice! Was looking for a good spray that didn't leave a residue but worked really well and am very happy to have found this one. Was hesitant because I couldn't find any reviews but this has worked great - it's the best non 'weatherproof' I've tried - weatherproof in South Florida summer is pretty useless so I decided to not bother, save a few bucks and have a happy, non greasy horse to ride on : )
