Top 10 Best Fly Sprays for Horses

#1 UltraShield Ex Fly Spray

Cost: $20

Made by the wonderful people at Absorbine, who also make dozens of other popular horse products such as liniment, UltraShield Ex Fly Spray was at the top of our list for many reasons.

UltraShield Ex is an enhanced version of it’s original formula, UltraShield, and works as both an insecticide and a repellant formula that will stay effective on your horse for an extended period of time.  While it may not always be as long as the 17 days, the brand claims, it definitely has a much longer duration than the majority of other fly sprays on the market.  So many sprays barely fend off flies minutes after you’ve drenched your horse with them but this one definitely lives up to it’s extended name.  It also is said to kill and repel more than 70 insect species.  We haven’t had the opportunity to use it on that many types of inspects, but in regard to every insect in the barn and pasture, it’s worked wonders.

What also makes this one of our favorites is that the UltraShield is sweat resistant and contains sunscreen and coat conditioners including aloe and lanolin that definitely benefit your horse.   If that wasn’t enough, it’s even safe to use on your favorite barn canines as well.

#2 Endure Sweat Resistant Fly Spray

Cost: $19-20

Made by Farnam Companies, Inc., Endure Sweat Resistant Fly Spray is another great repellant that continues to work in the most brutal and humid of summer conditions.   The spray itself is not only sweat resistant, but water resistant as well, which really helps to maintain it’s effectiveness after a full day at the horse shows or around the barn.

It contains sunscreen to protect against UV rays, as well as a coat conditioner that helps the repellant bind and stay put to fend off all species of flies.


#3 Tri Tec 14 Fly Spray

Cost: $19-20

Always been one of my top favorites.  I first chose to try Tri Tec 14 Fly Repellant because of it’s pretty silver bottle.  It combines pyretherine and cypermetherin (two aggressive ingredients for fly and insect control) to knock out house, stable, deer, and horn flies, as well as ticks, gnats and mosquitoes and is said to last up to two weeks.  Realistically, I’ve never seen it last that long, but it’s definitely affective for days, as long as your horse isn’t sweating it off or is getting rinsed off after riding.   Anything I’m not reapplying before the time I finish tacking up my horse or during my ride is great, and this one is effective well after.

It also includes sunscreen for UV ray protection which is always greatly appreciated!


#4 Pyranha Wipe N’ Spray

Cost: $19 for 32 oz

A great fly spray, Pyranha Wipe N’ Spray is extremely effective in temporarily repelling annoying insects, including flies, mosquitoes and gnats, without having to drown your horse in it.  Just as the name suggests, you can either spray it or wipe it onto your horse’s coat.

It contains lanolin as a coat conditioner, which is specifically added to give it a nice sheen when it’s brushed out, making it great for horse shows.  I’m also a personal fan of it’s citronella smell.

#5 OutSmart


For horse owners worried about harsh or toxic chemicals in their fly sprays, this is the one for you.  It’s made with plant-based ingredients and is free from permethrin, pyrethroids, pyrethrins and DEET.   It’s active ingredients are geraniol and peppermint oil, which gives it the most lovely and appealing smell.  Another bonus is that it’s safe to be used by the rider as well.

#6 Flysect Super-7

Cost: $19-20 for 32 oz

Another favorite from Farnam Companies, Inc is the Flysect Super-7.  It definitely has a decent length of effectiveness, containing 2 different fly repellants, plus pyrethrins and permethrin.  It effectively kills all annoying barn flies without having to soak my horse in it or reapply immediately after.

This spray contains aloe and lanolin to help condition your horse’s coat, as well as PABA sunscreen for awesome UV protection.

#7 Mosquito Halt

Cost: $17

While this spray is amazing to target areas with nasty mosquito infestations, don’t let the name fool you… it’s also extremely effective on all your standard barn insects – stable/face/house flies, gnats,  mites and even lice.

It contains two insecticides and two repellents, including permethrin, as well as sunscreen protection.   It lasts a pretty well, not to mention you save yourself a few dollars per bottle!

#8 UltraShield Green Fly Repellent

Cost: $20

Another good fly spray for you environment advocates, UltraShield Green Fly Repellent, made by Absorbine, is Eco-Safe for every one at your barn including foals, ponies, and dogs.

Works great to repel flies, mosquitoes and gnats for a few hours, (claims up to 8) just not as necessarily as long as some of the other brands do that contain the more effective chemicals.   Active ingredients include geranoil, clove oil, cintronella oil, rosemary oil, lemongrass oil, cedar oil and thyme oil, so you can imagine, it smells really really good!

#9 Bronco “E” Fly Spray

Cost: $8

For those of you not looking to break the bank on fly sprays, Bronco “E” Fly Spray made by Farnam Companies, Inc. is definitely a decent and more affordable solution at half the cost of other brands.

It’s both an insecticide and repellent for horses, ponies and foals, and it’s cheap enough that I also don’t mind using it as a “premise spray” for around the barn, spraying manure buckets and other areas where flies accumulate and breed.

It won’t last as long as the other sprays, and you may find yourself using a little more of it than the others as well.  You’ll also have to reapply after your horse sweats or he gets washed down (I typically don’t use this one before I ride on a hot day) but overall for the cost and savings, it definitely does an ok job and even knocks out flies in and around your barn.

I also love it’s citronella based scent.

#10 Repel-Z pe Emulsafiable Fly Spray

Cost: $20-40+ depending on size

One more from the top fly spray company on the market, Farnam Companies, Inc. for those of you who love to buy in bulk and dilute your own fly spray.   You save money buying it in it’s concentrated form, without the plastic waste, and can dilute it to your liking, even making it last longer.  It contains the ingredients prallethrin and piperony butoxide, for battling all types of flies, gnats, mosquitoes and other barn pests.

What I love about this, aside from it being a decent fly spray, is that you not only save storage in the barn (which can be hard to come by) as well as a ton of money!  The price you pay for the 32 oz concentrated bottle (about $40) which makes 8 regular 32 oz bottles of ready to use fly spray, would cost you about $160 to buy as individual spray bottles.  8 bottles for the price of two?  Or if you really want to save, you can get the gallon of concentrate for about $109 (the price of 5 and 1/2 bottles) which makes 32 full size (32 oz) bottles of fly spray.  With the cost of owning a horse these days, you really can’t beat this one.
