7 Best Fly Spray for Horses- Reviews & Buying Guides
As a horse owner, it can be disheartening seeing your poor horses covered in annoying flies. Not only do these insects annoy horses and their riders, but some of them can also bite. In the summer months, high humidity levels and heat make for the perfect fly breeding ground. If an onslaught of flies is tormenting your horses, you need the best fly spray for horses.
These sprays are meant to protect your beloved horses from harmful flies. With this guide, you will learn why these sprays are essential and how they can work to keep your horses more comfortable during the summer, when flies are most active.
Why Should You Use Fly Sprays for Your Horses?
If you are a new horse owner, you may not realize the dangers of exposing your horses to hordes of flies. One of the biggest dangers is the transmission of disease. Flies are filthy creatures and they live in cesspools. If they are carrying bacteria and diseases, your horse could be placed in danger.
While not all flies bite, most that hang out and irritate horses do. Stable Flies cause especially painful bites and they will attack your horse’s legs and flanks. These bites are so painful, they cause horses to stomp which could be dangerous if you are riding them. Stable Flies can transmit equine infectious anemia to your horses.
Horseflies attack the chest, neck, withers, and legs and they produce painfully annoying bites. Your horse could suffer from itching and painful bites all over when these incessant flies attack. Horseflies can also transmit equine infectious anemia.
Other types of annoying flies include Gnats, Face Flies, Horn Flies, and House Flies.
Not only do you have to worry about flies attacking your horses, but you also must worry about ticks and mosquitoes. Thankfully, the best natural fly spray for horses also helps to deter other biting insects from annoying your horse and causing them discomfort.

Top 7 Picks of the Best Fly Spray for Horses
As owners of a beloved herd of horses, there is no way we would compromise the health of our animals. We have completed hours of research into different sprays and their ingredients to come up with our top 7 best list of horse sprays. Read the following reviews to arm yourself with information on making a purchase.
#1) Pyranha Wipe N Spray- Most effective Fly Spray for Horses
One of the first things that impressed me about this spray is the size. I know it shouldn’t matter all that much, but when you have a lot of horses as I do, you will need a large container or you are going to be buying spray bottles over and over.
This Pyranha Wipe N Spray is ready to use so you do not have to add water. Simply purchase a small funnel and some new spray bottles and you are ready.
This spray’s active ingredient is pyrethrum which has been proven to kill all types of flies, gnats, mosquitoes, and ticks.
Not only does it contain the ingredient that kills on contact and helps to repel flies, but it also contains lanolin to condition your horse’s coat. The citronella scent is pleasant and you only need about one to two ounces per horse. A little goes a long way. As always, I tried a small bit on my horse’s skin before a full application and waited twenty-four hours. When no reactions occurred, I sprayed and brushed them all down. I was amazed to see flies landing but immediately dying! This stuff really does what it says.
- Proven to kill a range of flying and crawling insects on contact. They literally drop like flies!
- The addition of lanolin conditions the horse’s coat for added sheen.
- A large one-gallon bottle will last a long time.
- This spray contains these active ingredients: 0.1% Pyrethrins, 1% Piperonyl butoxide and 15% butoxy polypropylene glycol.

#2) Farnam SimpliFly Featuring LarvaStop- Best fly protection for Horses
When researching the different best fly spray for horses, I could not find many sprays that killed fly larvae. When flies land on horses, they often leave their eggs behind and these can cause skin irritations.
This Farnam feed additive really helps to reduce the flies in your barns and pastures.
Yes, I know it is not a spray, but I had to include it in this list because it really works. If you have ever seen the number of flies hanging around manure piles, you know it is important to do something to bring their numbers down or your horses will never be at peace.
The active ingredient in these pellets is Diflubenzuron. Diflubenzuron interrupts the life cycle of the fly so it dies before it ever reaches adulthood. It is safe for horses, but you should carefully follow directions for the best results.
I was a little concerned my horses would immediately shrug it off. They are rather spoiled with their feeding habits. The formula said it was highly palatable so I gave it a try and was quite impressed. My horses gobbled it right up with the rest of the feed. ( Check for best feed for horse weight gain ) So, then I had to wait to see if it made a difference.
Their manure looked and smelled the same, but I immediately noticed fewer flies hanging around. With fewer flies, my horses were not swatting their tails or stomping as much which let me know this product was doing as promised.
- This product is easy to use. You simply add it to your horse’s current feed and allow them to eat it.
- These pellets contain an active ingredient called Diflubenzuron and it helps destroy flies in all stages of life.

What is neat about this spray is it can also be used as a perimeter spray for added protection against annoying flying insects. This product is safe for use on horses, ponies, mules, and even dogs.
To tell you how respected this spray is, they are the official fly spray brand of the United States Equestrian Federation. I figured if they trust it, I can surely use it on my animals.
This stuff really does last a long time. I was quite impressed that it kept working even on two of my horses that are profuse sweaters. While I did not get a full seventeen days of work out of one application, it does last around two weeks which is fine by me.

Farnam has patented their RepeLock conditioner which is proven to completely coat the shaft of the hair, protecting against flies and ticks that may carry Lyme Disease.
Endure comes in three types, for your convenience. There is a pump spray, a roll-on, and an EZ pour gallon.
I recommend buying the gallon size if you have a large herd to cover. This spray claims it is a sweat-proof and weather-resistant so I used it on my biggest horse and boy does he sweat!
I have to say, Farnam Endure passed the sweat test with no problem at all. This is not concentrated so you do not have to worry about mixing it with water. It is ready to go right when you open the bottle.

The lanolin in the spray acts as a coat protectant and conditioner and your horse will definitely shine when you use it as directed.
What I really like about Pyranha’s horse sprays is they smell really nice. Your horses will not be repelled by the smell, but the flies and other insects sure will be! I applied and carefully brushed my mare and her coat was beautiful. From the very first application, she was much more comfortable.
You can apply this product with a cloth or with the spray. Either application requires your horse to be clean so make sure you brush them thoroughly to remove loose hair and dirt.

I found this ointment to be more like a paste. I usually put this product on my horses’ ears and polls to add extra protection to these sensitive areas.
It is important to note that if your horse has a deep wound, do not apply the ointment directly into the wound. Deep wounds should be protected with an edge application only. Apply it around the edge of the ointment so the wound is not irritated.
As always, it is important to use care when applying around the eyes. Use a light layer above and below, but never get too close to the eyes because it may cause irritation.

_Things to Consider Before You Purchase a Best Horse Fly Spray_
As with all things, not all fly sprays are created equal. Careful research is imperative for choosing a spray. It is important you consider a few different things before making a purchase.
One of the most important considerations when purchasing the best-rated fly spray for horses is the ingredients. Some fly sprays contain ingredients that are not entirely beneficial for your horse. Although they have been deemed safe for use, they can cause skin irritations, especially if your horse has sensitivities. Carefully reading the list of ingredients and knowing what each one does is important. The following are some common ingredients in fly sprays for horses.
- Pyrethrins – Pyrethrins come from the chrysanthemum flower and are all-natural. This is one of the best ingredients for deterring flies with vapor smells. This spray helps to create a strong vapor barrier that keeps flies and other biting insects from landing on your horse.
- Permethrin – This ingredient provides a coating on the horse’s coat and it works in two ways. It helps to repel insects, but it also kills them on contact. This is one of the stronger ingredients and it will not break down in exposed sunlight, making it ideal for all-day protection.
- Piperonyl Butoxide – This ingredient works as an insecticide and is meant to kill annoying flies and insects of all types. It also prevents flies from being able to metabolize permethrins and Pyrethrins so they are more effective in deterring these insects.
- Citronella Oil – This natural ingredient helps to repel flies and other insects, including mosquitoes. Its scent is pleasing to the human nose, but insects seem to detest it. Incidentally, Citronella Oil is also used in many topical and candle insect repellents for humans so it is considered a safe ingredient.
You need to make sure the horse fly spray does not contain any ingredients that could be harmful to your horse. Your horse’s safety and health are your highest priority. If you do not recognize the names of any ingredients, make sure to research them and ensure they are truly safe and do not have any undesirable side-effects that could cause harm to your horse.
Researching the different options and reading horses fly spray reviews will help to ensure you are able to make a wise choice. Although reviews should not replace your own research, they can complement the information you glean from your studying. If there are a lot of bad or negative customer reviews, you may want to choose another product. Consumers are fairly quick to inform others if they are not happy with a product.
If your horses are quite active and sweat a lot, you may want to consider purchasing a sweat-proof fly spray. Some sprays are more likely to be ineffective if your horse sweats a lot. The sweat can water down the spray or wash it away completely, depending on the level of sweat. Choosing a sweat-proof spray will allow it to stay in place without becoming weakened when your horse is sweating profusely.
Frequency of Application
Before purchasing any fly spray, you need to check how often it needs to be applied. We recommend purchasing a fly spray that is going to last at least one to two weeks. This is especially important if you are managing a large herd because the application can be tedious and time-consuming.
