A truly new alternative to traditional fly products containing pyrethrins or essential oils. Ecovet is a proprietary mixture of natural food-grade fatty acids and silicone oil. These are blended with Ecovet's special fragrance that includes sage and lavender. The sprayer and bottle combination was designed to provide an easy-to-hold application system that allows for a more pleasant spraying experience. Ecovet creates a "zone" of repellency that prevents the pests from landing on your equine friend.
