Top-10 Horse Fly Sprays
Loved in the USA

The Absorbine UltraShield EX Combo is a strong choice if you need a versatile insect spray that not only kills but also repels a wide range of bugs, including flies, mosquitoes, ticks, and more. Its active ingredients—pyrethrins, piperonyl butoxide, and permethrin—are known for effective pest control. A big plus is its long-lasting protection of up to 17 days, thanks to its weatherproof UltraBond Technology, which means it holds up well even in tough outdoor conditions. The spray is ready to use with no mixing required, making application simple whether you’re spraying horses, dogs, barns, or outdoor areas. The citronella scent is a natural choice that many users find pleasant, and it includes added sunscreens and coat conditioners, which is great for protecting your animal's skin and coat while fighting insects.

Because it contains permethrin, it should be used carefully and only on animals older than 12 weeks, as it can be sensitive for younger or certain pets. Also, while water-resistant, heavy rain might reduce its effectiveness before the full 17 days. This product is especially suited for horse owners looking for a reliable, easy-to-apply spray that works against many insect types and lasts well in outdoor environments. For those seeking something gentle for sensitive areas, consulting a vet is recommended, but for broad insect control combined with skin protection, this spray is a solid pick.

The Absorbine UltraShield EX 128oz Insecticide is a potent option for those needing a robust solution to repel and kill a wide array of pests. It boasts a strong formula that can tackle over 70 types of insects, including flies, mosquitoes, ticks, and fleas, making it versatile for use on horses, dogs, and even around barns and premises. The product's UltraBond Technology ensures it remains effective for up to 17 days, which is notably long-lasting compared to many other products on the market.

It's ready to use right out of the bottle, requiring no mixing, which simplifies the application process. Additionally, the water-based formula is a plus for those looking for easy cleanup and less sticky residue. Its weatherproof properties mean it will remain effective even in less-than-ideal conditions. The inclusion of sunscreens and coat conditioners is a thoughtful touch, providing additional care for your animals' coats while protecting them from bugs and UV rays.

However, potential users should be aware that, while the product is powerful, it might not be the best option for very sensitive areas or animals with particularly sensitive skin. For those looking for a comprehensive and long-lasting insecticide, Absorbine UltraShield EX offers a wealth of benefits. It is particularly well-suited for horse owners who need a reliable, weatherproof solution with added coat care benefits.

The Farnam Repel-X pe Fly Spray Concentrate is designed for horse owners seeking an economical and effective solution to control flies and other pests such as mosquitoes, ticks, and gnats. Its active ingredients, Piperonyl Butoxide combined with permethrin, provide broad protection against common stable and pasture insects. As a concentrate, it can be mixed with water to make up to 32 quarts, making it cost-effective for regular use.

This spray is suitable for application not only on horses but also on dogs, adding versatility for mixed animal households. It features a pleasant scent, which benefits both animals and handlers. Application is simple — dilute and spray — facilitating convenient regular treatments. Care should be taken around sensitive areas like the eyes and mucous membranes, although it is generally safe for use on horses and dogs.

The concentrate is not waterproof, so reapplication might be necessary after heavy sweating or rain. For those needing a strong, multi-purpose insect repellent that covers a variety of pests around animals and barns, this product provides good value and ease of use, especially for users comfortable with mixing concentrates.
