This Marigold Spray is a safe, non-insecticidal spray. It's the equivalent of planting marigolds in your garden; the bugs disappear. It moisturizes skin and promotes a healthy coat, working up to 8 hours. Skin and hair are not damaged or dried out. Because it's non-slip, it can be used on the saddle area. It won't hurt the horse's eyes. EQyss products are 100% CRUELTY FREE. All EQyss products are 100% SATISFACTION GUARANTEED & made with all natural, botanical ingredients wherever possible.
