And when it comes to caring for your horse, nothing is quite as important as the right conditioner, shampoo and fly repellant. Like horseshoes and periodic brushing, fly repellents are important for the proper care of your prized steed. Fly repellants keep them clean, comfortable, and devoid of diseases. A great fly repellent could potentially save you thousands and lengthen the lifespan of your favorite horse. It is an investment in itself and every horse owner should look into getting one. This guide was written to help with that. We will go over what to look for in a great repellent and help you pick out the best fly repellent for horses.



Any responsible horse owner and equestrian knows how dangerous flies, fleas and gnats can be to a horse’s health. Some of them carry life-threatening diseases that could affect the horse and rider.

There is always a noticeable dip in performance when a horse is in pain. That is why you must make your horse feel safe and comfortable. This means choosing products that contain the right ingredients and delivery system.

With these specifications in mind, these are some of the features to look out for when selecting a fly repellent for your horse.

The Right Ingredients

Any great fly repellent worth its mettle has to come with the right ingredients. It doesn’t matter whether the product you go with is natural or not. There are chemicals or ingredients that constitute the base expectation for both kinds of products. For the chemical fly repellent, you should look out for chemicals like Pyrethrin, Benzyl Benzoate, Citronella, DEET, PMD, and Permethrin. If the product you end up with isn’t with these ingredients, then you should do some research and read reviews before you commit to it. For natural products, you should look out for ingredients like Geranio, Clove oil, Peppermint oil, and Thyme oil.

It’s important that you know what is in the product you decide to settle with because of the side effects it can have on the other animals in your barn, not just your horse; most fly repellents aren’t made for just horses. The ingredients inside also tell you a little bit about how long the product lasts for before you need another application, as well as how effective it is. The ingredients can also tell you how many insects the product repels and the kind of scent it gives off.

The Delivery Method or System

When applying a fly repellent, it is mandatory that you apply the product evenly across the body of your horse; otherwise, it won’t be as effective as it should be. Ideally, you want to choose a delivery system that will spread the repellent evenly across the horse’s body. That means you want to go with products that come in sprays, liquids, soaps or shampoos. They have the best delivery systems and are the easiest to control.

Now that you have a pretty good understanding of what to look out for when choosing a repellant, let’s look at our top 12 picks. They are the best fly repellents for horses on the market.
