Top 10 Best Fly Spray for Horses Reviews & Guide

When working with horses, you often have problems controlling the irritatingly persistent flies that continue swarming your animals around the area.

They are annoying, but the flies can also be carriers for human and horse-related diseases. When flies land on the horse’s legs, horses tend to stomp hardly, which may cause damage to their legs and feet.

Flies have an enormous bad effect on humans and animals. Their painful bites can make both humans and animals stressful and unpleasant while doing some activities. Additionally, large numbers of flies cause lower weight gains and milk yields.

How to Choose the Best Fly Spray for Horses

After giving you the top-rated and best fly sprays for horses, we will help you choose the suitable fly spray for your horses. Below are important factors to consider to simplify the options for a fly spray.

  • Ingredients – The ingredients are obviously what will make the fly spray effective. If you are concerned with chemicals or want a natural repellent, look for essential oils in the ingredients. Also, consider using organic or natural-derived components that are safe for both animals and our environment.
  • Dosage of application – If you’re not able to reapply often, go with an oil-based spray, as it will last longer. Most sprays advertise that they will last for up to 14 days; they must have tested the horses in air-conditioned rooms with zero weather conditions to consider. Because in reality, the spray will protect your horse for closer to 2 or 3 days, so regular applications are vital. Water-based sprays make reapplication all the more important, as it does not stay on the coat quite as well.
  • Type – If you’re treating more than a few horses, or if you’re regularly applying, you may prefer an aerosol fly spray, as you hold down and let it spray. Traditional spray bottles require constant spraying and often don’t get applied evenly.

Frequently Asked Questions (FAQs)

This section gives you the most common questions about using fly sprays for their horses. Below you can see the corresponding answers.

What Makes a Fly Spray Works So Well?
Insects and bugs use scents to find things. Some odors attract bugs, and some repel them. Some of the fly sprays in the market have food-grade fatty acids that mimic several repellants smells that animals naturally have on their skin. In this way, the fly sprays’ unique formulations used the insect or bug’s own navigation against itself by overwhelming the system.

What is the Difference Between Oil-Based and Water-Based Fly Sprays?
The advantage of oil-based fly spray is that it is long-lasting, and it will remain for more extended periods of time. On the other hand, the water-based fly spray can be used when you want a non-greasy feeling to your horse’s coat, and it won’t accumulate debris and dirt as much as the oil-based one.

What Essential Oils Repel Horse Flies?
Essential oils are beneficial and considered safe to use, especially when you want to repel horse flies and prevent them from coming into your horses and other animals. These organic ingredients are commonly used in household and skincare products for fragrance and aromatherapy purposes. To minimize flies, check the fly sprays’ ingredients and search for eucalyptus, tea tree, or citronella oils.

What Types of Insects and Pests Will a Fly Spray Repel?
Typically, a fly spray repels and kills mosquitoes, various kinds of flies such as horn flies, stable flies, black flies, deer flies, face flies, barn flies, house flies, and ticks no-see-ums, which cause difficult to treat allergies, and cockroaches. Some recent studies and experiments confirmed very low toxicity to honeybees.

How Often Do I Need to Apply Fly Spray to my Horse?
Most of the best fly sprays in the market are long-lasting. So, you typically need to apply it every one to three days, depending on ambient temperature, fly pressure, and rain. For certain conditions, some veterinarians usually recommend initially treating the horse twice a day until the problem is under control. Some types of fly sprays work by evaporating and creating a repellent vapor barrier. If the horse is sweating, it may evaporate slightly faster.

What is the Best Way to Use Fly Spray to Help My Horse?
Focus on treating the regions that give your horse the most trouble, usually the mane, tailhead, and ventral abdomen. To start, apply a liberal amount until control is achieved. It may be best for an allergic horse to start with twice-a-day treatments focusing on these regions. Sometimes, you can use a soft cloth or mitt, which allows for a more effective way to apply your chosen fly spray.

Can I use the Fly Spray for Dogs, Pigs, and Many Other Animals?
While most fly sprays are effective against ticks, these fly sprays are specifically made and designed for horses and cattle. But some brands formulated fly sprays that can be used by many kinds of animals like dogs and many others. Before using it for your other pets, we suggest you talk with a trusted veterinarian to make sure. Please check the labels thoroughly if that fly spray brand can be used on some of your small animal companions.

Flies and mosquitoes are the most common external parasites of horses during summer. They irritate and spread diseases. Large numbers of insects on a horse can result in excessive blood loss.

Fly bites also can cause skin allergies due to hypersensitivity or allergic reactions. These annoying flies can disrupt grazing as horses may run to escape and get away from biting flies or seek shady areas to cluster together and swish and stomp.

Your diligent management can control them. You can do this by keeping flies from reproducing as you eliminate breeding sites, keep larvae from hatching like using oral larvicide to your horse’s grain, and especially, you can use the best fly sprays for your horses, protecting them from flies and other pests.

Therefore, the aforementioned top-rated fly sprays for horses are available in the market, so you can choose and buy what is appropriate for your horses as well as what is the most convenient product among them.
