10 Best Tick Repellent For Horses 2026 in the United States

The Absorbine UltraShield EX Combo is a strong choice for horse owners needing reliable protection against ticks and many other insects. It uses pyrethrins, piperonyl butoxide, and permethrin as active ingredients, which are known to kill and repel over 70 types of bugs including flies, mosquitoes, and lice. One of its biggest benefits is its long-lasting effect, offering up to 17 days of protection thanks to its UltraBond Technology, making it suitable even in tough weather conditions.

The formula is water-based and ready to use, which means no mixing is required—this makes application straightforward and less messy whether you’re spraying your horse, dogs, or barn areas. It also includes sunscreen and coat conditioners, so it helps protect your horse's skin and keeps their coat healthy while fighting bugs. Safety-wise, it’s made for animals older than 12 weeks, but as with all insecticides, it's important to follow the instructions carefully to avoid any side effects. The citronella scent is pleasant and natural, which many users appreciate compared to stronger chemical smells.

Some horses with very sensitive skin might react to the pyrethrin-based ingredients, so testing a small area first is wise. Also, while the spray works on many insects, it’s good to combine it with other preventive measures during heavy tick seasons. This product is well-regarded for its effectiveness, ease of application, and broad pest coverage in one spray, making it a solid pick for horse owners wanting comprehensive insect and tick control.

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.

Farnam Endure Fly Spray is a liquid insect repellent designed specifically for horses, targeting a wide range of pests including ticks, flies, mosquitoes, gnats, and lice. Its main active ingredient is Permethrin, a common and effective chemical for repelling and killing these insects. One of its biggest advantages is its long-lasting protection—up to 14 days—which means you don’t need to reapply frequently, saving time and effort. It also features Repelock technology, which helps the spray stick to the horse’s hair even in hot, humid, or rainy conditions, making it ideal for active horses that sweat or spend time outdoors.

This sweat-resistant and rain-ready formula works well during training, competitions, or daily turnout. Application is flexible since you can use it as a spray or wipe it on, including on sensitive areas like the face and legs, which is a helpful feature for thorough protection. The product has a pleasant scent and is suitable for horses of all ages. On the downside, because it contains Permethrin, it’s important to follow safety guidelines, such as avoiding use on cats or animals sensitive to this ingredient.

Some users might find the large 128-ounce refill bottle heavy to handle, but it offers good value for frequent use. Farnam Endure is a reliable choice if you want a durable, broad-spectrum insect repellent that keeps ticks and other pests away from your horse with minimal hassle.
