Best Horsefly Repellent

Flies are more than just a nuisance for your horse because they can spread illness. But how many times have you used a fly repellent on your horse and been disappointed? We’ve gone through hundreds of repellents to figure out which ones work the best. We’ll share our techniques for utilising sprays, so they’re most successful, as well as the six-horse fly sprays that proved to be the most successful.

Horseflies are the most aggressive, hard to avoid biting insects. These pests will fly up and scratch along your horse’s skin right by their eyes, inside the ear, or even underneath the tail of your horse. The results can be severe itching or infection, which is why it’s important to keep them at bay with an effective fly spray.

Horsefly sprays act as a bug repellent for your horse, but they can also block nerve impulses to reduce the sensation of bites immediately after application. This allows you to brush off the flies and remove any eggs before further irritation occurs. Some products also include sunscreen, insect growth regulators (IGRs) or other chemicals to minimise the number of bites.

Why a horsefly repellent is needed

The following are reasons why you need a horsefly repellent:

  • To protect your horse from nasty bites.
  • To protect you and your family from possible diseases contracted through insect bites. You may not be aware of them, but some insects (and their bacteria) carry diseases like West Nile virus or Lyme disease, which can affect humans and animals.
  • To help reduce threat of bruises to tender areas on your horse’s body.
  • To protect your horse from the aggravation of flies swarming around them making it difficult for them to eat or rest comfortably.
  • To avoid loss in performance because your horse is constantly swatting bugs away instead of focusing on you and complying with your aids. 
  • To keep your horse from getting annoyed to the point that they start swatting at you or nip out of irritation.

What are horsefly repellents made of?

Horsefly repellents are either made up of synthetic chemicals, or they’re made with natural ingredients like citronella and neem oil. The former can provide very quick relief against biting insects (even though some people don’t like the smell), but the sprays with natural ingredients typically take longer to be effective.

The products that worked best for us are the sprays with ingredients that repel biting insects slowly over time, so you have more control of their effects. This made it easier to combine them with other products, like sunscreen or insecticides, for added protection outside of horses shows.

What to look for in a fly spray

Horsefly sprays come in many forms:

  • Horsefly sprays can be used either directly on your horse like a traditional fly spray or in combination with other treatments or insect mixes.
  • Spray bottles are best for large areas, while aerosol cans provide more directed coverage.
  • Trigger sprays release more liquid than pump sprays allowing you to get the product where it needs to go with minimal overspray.

Horsefly sprays offer both quick relief and longer-term effects, but those that last the longest are typically not as effective for immediate bugs upon application. They need time to penetrate the skin and repel biting insects over hours instead of minutes.

Factors to consider before purchasing horsefly repellents

Below are some of the things to put in mind when looking for the best horsefly repellent:

1. Ingredients

Ideally, you want a fly spray that contains ingredients like DEET and citronella, which effectively repel insects. Other chemicals commonly found in sprays are permethrin and IR3535; these provide limited protection but can be effective when combined with other ingredients.

2. Effectiveness

The “best” horsefly repellent should provide both immediate and long-term protection. This prevents excessive irritation to the skin from bites and long-lasting consequences that can affect your horse’s health.

3. Application

How you apply a fly spray is important because it will determine how quickly you can move on with other tasks and which parts of the body you can spray. The most efficient ways to apply a repellent are by spraying it on a rag and wiping your horse down or in a trigger-spray bottle that you can directly target specific areas.

4. Safety

Look for a safe product to use around both humans and animals. This will ensure you don’t accidentally get it in your eyes or on other body parts that can cause irritation.

5. Ease of use

The best horsefly spray is one that can be easily applied and requires minimal clean up afterwards, especially if you’re using it for show. This also means not having to worry about over-sprays when working with trigger bottles, which is especially important when using other products affected by the repellent.

6. Price

For most people, the price of a fly spray is one of their major concerns, which is why we’ve included some affordable options in our list below. However, keep in mind that cheaper options may only provide limited protection and work quickly, while more expensive products generally last longer and provide stronger effects.

7. Reviews

Customer reviews can give you a good idea about a product’s quality and effectiveness before placing your order. Therefore, it’s best to look at the horsefly repellent reviews from people who have tried out different brands themselves since they have the most relevant information on how well each one works.

8. Horsefly control

While most products focus on horsefly bites, some also include other bug prevention that can help you better protect your horse. This includes ingredients like permethrin and p-menthane-3,8-diol (PMD). While PMD is not an insect repellent itself, it is found in many sprays and is used in combination with other chemicals to provide a synergistic effect against bugs.
