We're sorry, but certain colors/sizes are sold out and are no longer available.

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'!).

Rated 5 out of 5 by from Effective product This is my second year using this product. Does the job.
Date published: 2016-06-27
Rated 5 out of 5 by from The most effective fly spray I've used in years! This stuff keeps the flies off and they stay off! Better than Pyrana! I'm so glad I tried it! Plus, I got a free fly mask with the purchase and its a good one! All it needs is a batman insignia and I would have "Bat horse!"

Rated 5 out of 5 by from This stuff really works! The first fly spray I have EVER used that actually works. I'm now confident my mare is protected and comfortable during turnout. I really am in shock how well this works. I thought maybe the bugs weren't bad until I tried another brand one day...the bugs are out! This is really great stuff.

Rated 5 out of 5 by from Best fly spray for my horses! Best fly spray for my horses! I get the best protection for them compared to other sprays. Works best with consistent usage.

Rated 5 out of 5 by from Definitely helps control flies a great product and the gallon size is convenient. I do see a real difference in fly control.

Rated 5 out of 5 by from Good fly spray works well. Holds up under horses sweat as well.
Date published: 2016-06-21
Rated 5 out of 5 by from Works Great! I live in MS where the humidity can be fierce come summer time (sweaty horses) as well as the flys. I noticed immediately the decrease in horse fly bites on my horse due to the sweat resistance of this product.

Rated 5 out of 5 by from Best fly spray I've ever used! This is hands down the best fly spray I have ever used, and not only have I tried pretty much any one on the market including concentrates...I've also made my own with several different DIY recipes. It's a little pricey but worth EVERY penny. I've used some that you spray it and a fly lands on ur a second later before it's even dry. With UltraShield the effects are instantly visable!!!!!! Sun screen and coat conditioner are also a big plus!

Rated 5 out of 5 by from Best fly spray on the market I've tried all kinds of fly spray, and while none are fool proof, this one is decidedly the best. It works for a pretty solid 48 hours or longer depending on weather. I live in North Texas and we have some serious flies. When the horses are sprayed you notice that their tails stop swishing. I combine the use of this fly spray with fly tape, fly predators and my horses are turned out with fly sheets.

Rated 5 out of 5 by from No welts from bites! Quality, effective bug spray....may thin-skinned Appendix Quarterhorse can't tolerate summer bugs yet enjoys his ability to go from stall to paddock at his leisure. With Ultra Shield he can remain out well into the evening free of dangerous and annoying bug bites.

Rated 5 out of 5 by from Effective Protection This has the most repellency on the market!!! Excellent for ticks & mosquitos
Date published: 2016-06-01
Rated 4 out of 5 by from Solid fly spray Ultra shield is my go to fly protection and it usually works great. The spray bottle is solid and the smell is not bad. However, it doesn't do much for swarms of black gnats. Had those at our last show and this one did very little to help.
Date published: 2016-05-24
Rated 5 out of 5 by from I've used this for years! Really like that this contains a sunscreen. Works great for the biting bugs.
Date published: 2016-05-23
Rated 5 out of 5 by from Easy use! Great coverage I bought the UltraShield aerosol fly spray with hope for easy application. This product has excelled my expectations! I was worried my spooky Arab would have the aerosol but he doesn't mind it at all. Quick easy sweeping coverage that goes on easily! Absolutely love it!

Rated 3 out of 5 by from Works pretty good Seemed to work pretty good, though only for 2 or 3 days. Not the 11-14 they claim. Granted, we have had some wet weather.
Date published: 2016-05-02
Rated 4 out of 5 by from Effective, smells ok I have used many brands and formulas. This seems to be the most effective in our area. We have mostly gnats, face flies, and some Mosquitos. I took off a star since it says it will kill bugs for up to two weeks. Yeah right! While it does work well, I find I need to apply at least twice a week.

Rated 5 out of 5 by from Love this product! Best fly spray I've found with no residue left on my horse!

Rated 5 out of 5 by from Best you can buy We get some nasty flies in July through September, especially on the trails. This is the only product that helps.

Rated 5 out of 5 by from Repels ticks The best product to repel just about everything. Been using it for years.

Rated 5 out of 5 by from best fly spray on the market forget everything youve ever been told. THIS is the best fly spray ever, my horses have lived in hot humid fly infested south america, theyve lived in florida, anywhere they go this fly spray ALWAYS WORKS. been using for years will continue to buy.

Rated 5 out of 5 by from Killer Spray! I will not switch from Ultra Shield Ex fly spray. I know it works and I'm confident it lasts as promised. Flies are out with a vengeance in my area, but when I spray them they drop to the floor to be swept out! Like the sunscreen in it too.
Date published: 2016-03-25
Rated 5 out of 5 by from ONLY fly spray that works In Florida, the heat of the summer brings lots of flying insects, especially flies. This is the ONLY fly spray that works and kills flies on contact. The Ultra Shield red doesn't work at all.. but the black bottle... You'd have to pry it out of my hands.
Date published: 2016-02-29
Rated 5 out of 5 by from Best I've ever used. I live in Florida where you have to have effective control and this product is the best I have ever used.

Rated 5 out of 5 by from LOOOOOOOOVVVVEEE!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I love this fly spray where i live flirs are HORRIBLE! They cover my horse when he has not been sprayed , but with this spray, no flies are left.
Date published: 2015-12-30
Rated 4 out of 5 by from Love the spray but hate the bottle! The spray itself is probably one of the most long lasting fly sprays. But do not purchase the small spray bottle as it does not work properly. I used it once and am now going back to the regular bottles as the small one does not work anymore after only one use. It advises to shake before use but it has no effect on the spray at all. :(

Rated 5 out of 5 by from Ultra Shield Fly sprayq Have used them all and this is the best. Will never change and will always use

Date published: 2015-09-24
Rated 5 out of 5 by from Works GREAT - bye bye flies!! I've yet to meet a fly spray that can truly deter deer flies. This one comes the closest. And other flying pests? Fuggedaboudit. They don't stand a chance. I do like Pyranha aerosol spray and will alternate. Between the two my horse is pretty well buzz-free.
Date published: 2015-09-22
Rated 4 out of 5 by from Does a great job on the flies. Not sticky but stings the eyes so be upwind when you apply it. I have not found it to be lasting several days and reapply it every day.
