Farnam Equisect Water-Based Botanical Fly Repellent with Herbal Scent for Horses, Dogs, and Cats puts flower power to work to protect your horse from pesky flies. An insecticide and repellent derived from chrysanthemum flowers helps protect your horses, stables, and even your dogs and cats. The spray kills stable, horse, deer, house, and horn flies, as well as mosquitoes, gnats, and ticks. It’s alcohol-free and gets the job done without irritating sensitive skin. Plus, the spray is non-oily and won’t attract dust or dirt. The only thing this fly spray leaves behind is the therapeutic, herbal scent from citronella, clove stem, and corn mint essential oils for fly relief you can feel good about.
