The Different Types of Fly Sprays for Horses

Although horse sprays have different names, you can categorize them into three basic types. Here are the various types of fly sprays for horses.

Fly Killers 

The main aim of this horse fly repellant is to kill all flies it comes in contact with immediately. These kinds of prays are chemical-based, and the toxins in the chemicals are what kill the flies. 

To use this spray, apply it on surfaces like walls or floors, and any fly that lands there dies immediately! Until the mist evaporates, these kinds of sprays are 100% effective.

Fly Repellents

As the name suggests, the primary use of this horse spray is to put horse flies off your horse. This spray does not kill, but its smell prevents flies from landing on your horse. This spray is not as effective as the fly killer sprays. Some flies may ignore the smell and still land and feed on your horse.

Combination Sprays

These horse sprays are a combination of repellent and killer sprays. These sprays will repel flies and other insects due to their pungent smell, those that ignore the smell and land on your horse die immediately. The effect of such sprays lasts longer, so your horse will stay unbothered for some time.

What Repels Horse Flies?

Horse flies torture horses without surrender; various chemicals and scents repel horse flies. You can buy horse sprays from the vet or prepare some homemade horse fly spray for horses. Manufactured horsefly deterrents contain pyrethrins, citronella, permethrin, and other chemicals which repel horse flies.

These sprays act as horse fly repellant and shampoo, keeping your horse’s coat moisturized and shiny. You can make homemade horse fly sprays using white vinegar or apple cider; these two repel horse flies. You simply pour them into a spray bottle, add a little water, shake well and spray your horse. 

Other scents that repel horse flies include rosemary, lemongrass, catnip, cedar, eucalyptus, peppermint, and clove. If you consider buying manufactured horse fly repellents, our best fly spray for horses reviews below will aid you in picking the best option.

How to Apply Equine Fly Sprays

The method you will use to apply horse spray depends on the spray you buy. You must follow the guidelines given on the package you purchase. All products are different. Do not assume you know how a product works; always read the package first!

Some horses get uncomfortable with the sound and feel of the horse fly spray. For such horses, you should be slow and gentle! Start from the legs and work your way up slowly. Use a roll-on repellent for the head.

Remember, a horse spray should be sprayed from a distance, not too close, and not too far. When spraying from too far, the mist won’t cover your horse well, and if you are too close, you are likely only to cover a small area. Here are the various ways to apply equine fly spray on your horse:

Spraying

When using this method, check that your horse is clean and dry before spraying it. Whether using an oil- or water-based spray, your horse needs to be clean before spraying.

Ensure you spray from a distance of six inches away from the horse. This distance gives a bigger coverage and ensures the spray doesn’t miss.

Wiping

Wiping is a great alternative if you do not want to use pump sprays. You may consider this method if your horse doesn’t like spraying. This method is also effective when spraying the sensitive parts of your horse, such as the ears, nose, and mouth areas. 

Other than the face, you may also use it on other sensitive sites such as near open wounds. Remember to wear latex gloves when using this method.

How Long Do Fly Sprays Last on Horses?

Different horsefly repellents last for different amounts of time. The period it will last depends on the chemical used to make the spray and its strength. Some manufacturers say their sprays can last for four hours.

Others claim 24 hours, while some claim that their horsefly deterrent can last up to two weeks after application. Despite these claims, horse owners enjoy very different results from these products.

Reapplication can be affected by many causes, including the current wind conditions and the number of flies attacking your horse.

Factors to Consider Before Buying Equine Fly Sprays

Knowing which equine fly spray is good for your horse is not easy. When trying out a new brand on your horse, spray a small amount on your horse’s skin and see if they have an adverse reaction.

If your equine has sensitive skin, consider buying the all-natural fly spray for horses. Such sprays contain essential oils like rosemary, thyme, and lemongrass, which many insects do not like. These sprays contain no chemicals and are friendly to your horse’s skin.

Sweat-resistant fly sprays would work best for horses that do lots of work during summer. Such sprays remain effective even in wet conditions such as rain or sweat, ensuring your horse is well protected.

Buying the first fly spray for horses you see at your local shop is not a good idea. Here are more factors that you must consider before purchasing a horse spray for your horses:

Spray Type

As stated above, there are many types of horse spray that you can select. You may pick the sprays that kill flies, repel flies, or a combination of the two. The spray you choose depends on the number of flies that have infested your horse and your horse’s skin.

If the number of flies you are handling is large, you may pick the repellent spray. However, the mixed type would work great if there are too many flies! Because it repels and kills flies at the same time. Just be sure to pick a type that will not react with your horse’s skin since most of these sprays contain toxic chemicals.

Chemical vs. Natural

Many horse fly repellents use chemicals to kill flies. Manufacturers should pick toxic chemicals for flies but safe for humans, horses, and other animals. It would be best to avoid horse fly repellents with chemicals that have not been tested or are unsafe.

Natural substitutes do exist. These sprays use natural ingredients such as rosemary and citronella to repel flies. Citronella has a citrus smell which improves the scent of these natural sprays. It puts off flies and other insects because of its strong smell.

Most natural fly sprays for horses contain fatty acids as the active ingredient. This ingredient confuses the flies, leaving them unsure where the horses are.

Horse Needs

It is essential to consider your horse’s specific needs when buying horse spray. Kindly be more careful when purchasing horse fly spray for horses with sensitive skin, open wounds, or other health issues.

You must consult your vet immediately if you have any questions or notice severe reactions. Trying a new spray on a small patch of your horse’s skin first is an excellent way to tell if the product will adversely affect your horse.

Active Ingredients

The main ingredients used to make horse sprays differ from one brand to another. These ingredients may not be suitable for all horses, especially foals and lactating mares. To avoid harming your horses, check the ingredients and read the instructions before using horse fly sprays.

Reading the manual well will also protect you from harming yourself. If you are troubled about exposure to toxic chemicals, you may consider buying natural fly sprays for horses. These products do not contain toxins and are safe for you and your horses.

Water vs. Oil–Based

Every fly spray comes in an oil or water base. Although these two work well to protect your horse from flies, most people have their preference on which one they like. 

Oil-based fly sprays are more effective in fighting and keeping off flies. The flies drown or suffocate just when they land on the horse—however, oil-based equine fly spray attracts dust on the horse’s coat.

Although water-based sprays are less effective, they make it easy to keep your equine coat clean. They collect less dust than oil-based fly sprays. Other water-based formulas also have ingredients that make them all-weatherproof.

Other Horse Fly Repellant Strategies

Although horse fly sprays contain chemicals and toxins; they are very effective in protecting your horse from flies.

Several other methods can effectively repel horse flies. The most common horse fly repellent is horse sprays. Many equestrians use horse fly sprays to keep away flies. However, if you do not have a horse spray yet, you can use any of these alternatives to keep flies off your horse.

Apple Cider Vinegar 

Natural apple cider vinegar can effectively control flies. If your horse fly spray is over, you can use apple cider vinegar on your horse’s skin to keep away flies.

Apple Cider Vinegar 

Essential Oils 

You can also use essential oils to keep flies from bothering your horse. You may use any of the oils listed below or buy a premixed bug repelling essential oil mix. Here’s a list of some essential oils that you can use as horse fly repellents:

  • Citronella
  • Eucalyptus
  • Lemon Grass
  • Peppermint
  • Cedarwood
  • Lavender
  • Tea Tree

Horse Masks 

Using horse marks is another great way to keep flies off your horse! Masks protect your horse from the discomfort caused by flies on the eyes and ears. If you choose this method to repel flies, ensure you pick good quality masks since the other ones tear pretty fast.

Fly Predators 

Fly predators are a great way to keep flies away without using chemicals. This method is one of the most natural ways to deal with pesky flies. When using this method, you will ship small non-stinging wasps as larvae. After they mature, you will add them to your manure heap.

These small wasps minimize flies by eating fly larvae. This method is highly effective in controlling horse flies. However, it works best for large farms, so if you have a small barn with one or two horses, it cannot work for you.

Insect Growth Regulator

Insect growth regulator is a supplement you can give your horse to control horse flies. This supplement comes in pellet form, which you add to your horse’s food. The pellet is broken down at the end of the digestion cycle. 

When the flies lay eggs on your horse’s poop, the flies do not produce an exoskeleton; this means they cannot fly, move or reproduce, so they die before maturity. 

Add Garlic to Your Horses Food

Some claims state adding garlic to your horse’s food can help keep horse flies away. If you are considering this option, start with a small amount of one teaspoon and increase with time until you see the results.

You should not exceed two tablespoons per day. People using this method to control flies say the results are visible between 2- 4 weeks. Consult your vet before trying this option out.
