Homemade Fly Spray Recipes

Are fly spray prices killing your bank account? Even if you live in a climate where fly-spray isn’t needed year-round, it can still be a large expense for lots of horse owners! Many horse owners have to deal with the problem of flies year-round, while others that live in colder climates only have to deal with it for part of the year. Lets talk about homemade fly spray for horses.

Whichever category you fall into, you know that fly spray can sometimes seem overly expensive for a liquid spray.  Even if it’s “affordable,” the money you spend on fly spray could be used to pay for other things or even other horse-related expenses.

What if I told you that you could save mountains of money on fly spray, AND make sure your horse is receiving an all-natural fly treatment?  It’s true! There are many fly-spray do-it-yourself recipes that will not only reduce your fly-spray expenses but also ensure that your horse’s fly-spray treatment is all-natural and healthy.

Not to mention that refraining from buying tons of plastics bottles of fly spray will help reduce plastic use and will aid in helping the environment!!

In this article, I will be discussing four different home-made do-it-yourself fly spray recipes.  These recipes have some shared ingredients, but have some ingredients unique to themselves! 

4 Best Homemade Fly Spray For Horses

Recipe 1: Easy to make natural fly repellent

The first recipe comes from SaavyHorseWoman.com, and it is surprisingly simple.  The ingredients include the following list:


All of these ingredients, except the dish soap, are completely natural.  And, there is a very small quantity of dish soap included. One common ingredient that you will notice across all four recipes is apple cider vinegar.

TheSaavyHorsewoman.com emphasizes the importance of selecting high-quality apple cider vinegar and recommends using one that is organic and unpasteurized.  In a pinch, this site says you could also use only apple cider vinegar, and it will still help. Though it may not be as effective as producing the full recipe.

Recipe 2: Water-based horse fly spray

The next two recipes come from The Spruce Pets, which offers both a water-based recipe and a mineral oil recipe.  They say that the water-based spray is especially helpful in defending your horse from flies that will attack his face.  This recipe has the following ingredients: 


Again, note the use of apple cider vinegar.  The only ingredient in this recipe that isn’t natural is the Skin So Soft bath oil.  And even so, Skin So Soft boasts of using many natural ingredients in their products.

The Skin So Soft ingredient is especially aimed at deterring black flies.  So, if you live in an area where black flies are a concern, this may be a good option for you and your horses.

Because of the apple cider vinegar, this is also a spray you will want to make sure stays out of your horse’s eyes.  If it gets in your horse’s eyes, it could sting and be quite painful.

Recipe 3: Oil-based horse fly repellent

The third recipe also comes from The Spruce Pets and is their mineral oil recipe.  It has the following ingredients:

Although, they note that glycerine is optional.  Here, the only ingredient that is not natural is the lemon dish detergent.  You’ll also notice that many of these recipes use essential oils, such as eucalyptus oil.  But, this is one of the only recipes that does not use apple cider vinegar.

It is also noted that, while this spray is mostly natural and very effective, it is not recommended to use at horse shows.  This is because it attracts dust and will make your horse dirty.  So, if absolute cleanliness is a concern for you, this may not be your best option.

Recipe 4: White vinegar homemade fly spray for horses

The fourth and final recipe comes from Saddle Box.  Their recipe includes the following ingredients:

Recipe 4: White vinegar homemade fly spray for horses

Notice that this recipe does not include eucalyptus oil or apple cider vinegar.  The only two ingredients that are not natural are the spray-on sunscreen (which is arguably optional) and the liquid soap.


As you can see, there are many options to pick from outside of purchasing pre-packaged and pre-mixed fly spray.  There are really three benefits to doing this- 1) it will save you money, 2) you know exactly what ingredients are being used on your horse and can ensure they are mostly natural, and 3) you can reduce your carbon footprint by using less disposable plastic.

Now that you know the basics, you can also experiment with your own recipes! For example, now you know that many recipes use apple cider vinegar, and many recipes use eucalyptus oil.  Maybe you like this, maybe you don’t! Maybe you’ll come up with a recipe that works on some horses, but not others. It’s a fun process that could save you and your farm money in the long run.

There is proof to show that home-made do-it-yourself recipes like this really do work.  You may have to put a little bit more time into mixing it yourself, but the end result will be well worth it.
