Defend with mother nature with Nature's Defense Water-Based Fly Repellent Spray. Combining botanicals like citronella oil, clove oil, mint oil and thyme oil, this pest control product offers a fresh alternative to chemical sprays. The formula is gentle on skin and tough on flies. Free of alcohol, preservatives, additives and artificial colors, you can feel good protecting your horse without worrying about irritating their sensitive skin. This is an effective repellent that will keep away five common fly species (horn, stable, house, horse and deer), mosquitoes and gnats.
