Stop those pesky flies from annoying your horses with Farnam Repel-X Horse Insecticide & Repellent. This water-based formula protects against stable, horse, face, deer, house and horn flies, mosquitoes, gnats, ticks, fleas, chiggers and lice. This easy-to-use spray can be applied directly to the coat, or the premise to keep insects out of the vicinity. Repel-X is great for horses, but gentle enough to work on dogs, too! To apply, simply spray onto your pet, or onto a clean, absorbent cloth towel and wipe the body to insure adequate coverage.
