10 Best Tick Repellent For Horses 2025 in the United States

Absorbine UltraShield EX 128oz Insecticide is a robust choice for tick repellent for horses. As a ready-to-use, water-based formula, it simplifies the application process as no mixing is required. Its strongest formula is effective against over 70 species of pests, including ticks, flies, mosquitoes, and fleas, which makes it versatile for use on horses, dogs, and premises.

The weatherproof feature ensures protection for up to 17 days, thanks to UltraBond Technology, which is particularly beneficial for outdoor use. Additionally, the product includes sunscreens and coat conditioners, offering extra care for your horse's skin and coat. However, as with any chemical insecticide, there may be potential side effects or safety concerns, so it's advised to monitor your horse for any adverse reactions.

The size and weight of the container (8 pounds) make it somewhat bulky, which might be inconvenient for some users. Made in the USA, it assures good quality standards. This product is well-suited for users needing a long-lasting, multi-purpose insecticide for their horses and other pets.

The Farnam Endure Sweat-Resistant Horse Fly Spray is a liquid spray designed to protect horses from ticks as well as flies, mosquitoes, and other biting insects. Its active ingredient is permethrin, a common and effective insecticide known for repelling and killing ticks. One of its main strengths is its sweat-resistant formula with Repelock technology, which helps the spray stick to the horse’s hair even in hot, humid, or rainy conditions. This allows the protection to last longer—up to 14 days under ideal circumstances—though reapplication every 5 to 7 days is recommended at first and after heavy rain or washing.

Safety-wise, the product is generally safe for horses at all life stages when used as instructed, but it should not be used on horses intended for human consumption. It’s also important to avoid contact with the horse’s eyes, nose, and mouth during application. Applying the spray is straightforward thanks to the simple spray bottle, but for the horse’s face, it’s better to apply it using a cloth to avoid irritation. Users appreciate the pleasant scent and the convenience of different sizes available.

The requirement for reapplication after washing or heavy rain means it might need regular attention, and some horses could be sensitive to permethrin, so monitoring for any adverse reactions is wise. This product is a suitable choice for horse owners seeking a reliable and long-lasting tick and fly repellent that performs well even in sweaty or wet conditions.
