Things to Consider When Purchasing a Horse Fly Repellent

fly spray for horses

There are several important things to consider while looking for a specific product, namely:

Company Reputation

While a newcomer to the market could make a good horse fly spray, the guys that have been in business for many years have built up a reputation and a following, so their products must be doing something right.


Whether you have a few horses or many, the cost of horse fly spray can add up quickly; this is especially important when you consider all the other products needed and additional expenses.

You can’t simply compare two products of the same size to see which is better value for money as some need regular application while others will last a lot longer.

This means that the bottle will last much longer and save you money.

Natural or Chemical

Most products contain chemicals to repel and kill flies and other biting insects, while some are natural.

There are many good natural products, but there are also a number that simply aren’t very effective.

Conditioning and Sunscreen

Although these products’ main purpose is to repel flies, it is beneficial if they contain conditioning ingredients and sunscreen to protect the horse and keep their coat looking healthy.

Pleasant Smell

And of course, the smell! No one wants their horse smelling of harsh chemicals, so look for products that leave a pleasant smell (or no smell) even hours after application.
