- My Conclusion and Top Choice
I work with horses in a hot climate, and in the summer, flying insects bother them. I find it pretty upsetting watching my equine friends suffer from the flies, and the last thing I want when I’m riding is a twitchy horse. I’ve learned a lot about horse fly sprays over the years and know which ones are the most effective. So, if you want to know how to find the best horse fly spray on the market, I’ll tell you exactly how below.
Bottom Line Up Front
If you want a highly effective, long-lasting fly spray, I highly recommend Farnam Endure. This spray is sweat-resistant, so it’s fantastic for the show ring and provides days of protection for horses out in the field. Farnam is a brand you can trust, and that’s why horse owners all over the world choose their products for fly protection.

How Does a Horse Fly Spray Work?
Horse fly spray creates a protective barrier against flies and other biting insects such as stable flies, ticks, and mosquitoes. It does this with synthetic chemicals or organic substances that kill or repel biting insects. Repellents stop pests from landing on my horses, while insecticides kill the offending insects.
- Insecticide Sprays: Are usually made from fully-synthetic chemicals – they kill insects upon contact and are generally more effective at keeping insects at bay.
- Repellent Sprays: Contain organic repellents, which are less toxic for horses, but they don’t kill insects – they only deter them.
Common Ingredients to Look Out For In Horse Fly Spray
If I want to make an informed decision about choosing a fly spray, I look at the ingredients. I look for the base ingredients such as water or oil and the active ingredients such as DEET. If you’re not a scientist, it’s hard to decipher some of the chemicals in a fly spray – so I’ll break them down for you below.
#1 – Water or Oil
The first thing to look out for on fly spray is the base ingredient which will be either water or oil:
- Oil-based fly sprays Are fast-acting and evaporate slower, which means they last longer. However, oil-based spray can leave a sticky residue on your horse’s coat, which can attract dust – and even burn your horse’s skin if in strong sunlight.
- Water-based fly sprays: These are generally less irritating and more soothing to your horse’s skin. However, you usually have to apply water-based horse fly spray more frequently than oil-based ones.
#2 – Permethrin/Cypermethrin
Fly sprays which contain permethrins, such as cypermethrin, are generally more expensive because they’re highly effective. Permethrin is an insecticide – synthesized from chrysanthemum. It’s the strongest chemical repellent, which can defend against insects for several days.
#3 – DEET
You find DEET in many horses and human insect repellents because it repels most insects, especially mosquitoes. I like to use DEET products in places where mosquitoes are a problem.
#4 – PMD or Citriodiol
PMD is a plant-based compound derived from the eucalyptus tree. It’s naturally repellent which can be just as effective as DEET if you use it in the right concentrations.
#5 – Benzyl Benzoate
Benzyl Benzoate is a powerful insecticide and is the ingredient I look out for if I want to help a horse with sweet itch. However, I try to apply it before the itching starts in March because it can irritate the exposed or broken skin that comes from itching.
#7 – Neem
Neem is a natural ingredient in horse fly spray- it’s a powerful and non-toxic insect repellent that you can use on all animals. Neem does a fantastic job of keeping insects away and is also very soothing on the skin.
#8 – Citronella
Citronella is a common natural ingredient in horse fly repellents and has a pleasant and distinctive smell. Citronella is usually the main active ingredient in natural or organic horse fly sprays.
How Good is Natural Horse Fly Spray?
I don’t like to put chemicals on my horses, and there’s a range of eco-friendly, chemical-free sprays on the market. I like natural products because they’re much safer for horses and the environment, but unfortunately, they’re usually less effective than chemical ones.
If my horses are in an area with few biting insects – I use natural products to protect them. However, if my horses are in a place where biting insects are a real problem and causing them distress, the benefits of using chemicals outweigh the risk of toxicity.
Holistic Ways To Keep Flies Away From Horses
If you don’t want to use strong chemicals on your horse, you can use chemical-free fly repellents with holistic approaches to keep the flies away. Try feeding your horse a garlic supplement that will make your horse less appealing to flies, or use a fly sheet to help keep the flies off.
What I Look Out For To Choose The Best Horse Fly Repellent
Each horse is different with fly spray, so you must choose one depending on their circumstances and environment. I always look at the active ingredients, and I look for added extras such as sunscreen or coat conditioner.
Let’s take a closer look at the main things to consider when you choose a fly spray:
#1 – The Ingredients
The ingredients are the first thing I look at when choosing a fly spray. First, I check to see if it’s water or oil-based, and then I look for the active ingredients. If I want to protect outdoor horses for days at a time, I choose oil-based, permethrin cypermethrin products. These offer the most coverage and are sweat and weatherproof.
#2 – The Application Method
If I work with a freaky horse who doesn’t like spray bottles, I look for repellent, which I can apply with a cloth. Some sprays come as wipes or as a roll-on – these are great for nervous horses and to apply for protection around a horse’s eyes.
#3 – Your Horses Environment
If my horses live outside in a heavily infested area – I always choose the strongest products. If my horse is in a stable overnight, I find I can get away with a milder product because there are fewer insects indoors. Mild products are also better for indoor horses because there’s less ventilation.
#4 – Your Horses Skin
If I have a horse with sensitive skin or skin conditions, I don’t use sprays heavy in synthetic chemicals – you should never apply strong chemicals to damaged skin. Instead, it’s better to use a natural product – aloe vera is particularly good for horses with dry or sensitive skin.
Always perform a patch test on your horse before you use a new horse spray. Just because a product is natural, it doesn’t mean your horse won’t be allergic to it – some horses can react to the essential oils found in natural products. I’ll tell you how to do a patch test later in the article.
#5 – Added Extras
I often choose fly sprays with added extras such as sunscreen. Again, choose added extras depending on your horse’s circumstances.
If I want the spray to protect my horse in the show ring, I choose sweat-resistant ones with coat conditioner or coat shine. If my horses are outside a lot, I choose fly sprays with UV protection.
How Much Fly Spray Does a Horse Need?
The amount of fly spray I use on a horse depends on the brand and my horse’s needs. Some brands offer 14 days of protection, but, in reality, they usually last between 3 and 5 days. Other brands recommend a daily application. You can tell your horse needs more spray if flies start to bother them.
Groom your horse before applying the spray, and apply it liberally following the manufacturer’s instructions. It takes approximately 2oz of spray to cover a medium-sized horse, roughly 45 sprays. You can also reapply the spray when your horse needs extra protection, such as during the peak insect biting hours at dusk and dawn. Before applying a new spray, always do a patch test on your horse.
What is a Patch Test?
A skin test is when you apply a new spray to a small area of your horse’s skin, usually under their armpit, and leave it for 24 hours. This is to ensure your horse isn’t sensitive to the new product before you cover their body in it.
If the skin patch is normal after 24 hours, you can safely use the product on the rest of your horse’s body. If your horse has a bad reaction – you should choose a different product instead.

FAQs
Answer: The most effective equine sprays are ones that contain insect repellent or insecticides such as DEET or Permethrin Cypermethrin. Chemical pesticides are effective and long-lasting; they’re usually sweat and weather-resistant. Natural repellents are less toxic to horses, but they’re not as effective – usually, you have to reapply them every few hours.
Answer: Horse fly sprays can protect horses against a range of biting insects, including mosquitoes, gnats, flies, and ticks. Some sprays protect against up to 90 different types of insects. Not all sprays are the same – some are more effective than others, so for guaranteed coverage, always buy the fly spray from trusted equine brands.
Answer: You can use horse fly spray to get rid of horse flies outside, in the paddock, or inside the barn or stall. Some sprays are repellents, meaning they deter flies from landing, while others are insecticides, which kill the flies upon contact.
