Nature's Force Fly Spray is a ready-to-use insecticide built around a blend of clove, thyme, cinnamon, lemongrass, and peppermint oils. The formula is packaged in a 32 oz trigger-spray bottle and requires no mixing or dilution before application. It is labeled for use on horses, ponies, and dogs to control and repel biting and nuisance flying insects. Handlers shake the bottle well, turn the nozzle to the on position, and apply the spray evenly over the coat, paying particular attention to the legs, shoulders, shanks, neck, and ears where insects tend to gather. The coat should be brushed lightly after application, and the animal should not be saturated with product. The label directs users to avoid contact with the eyes, mouth, nose, and genitalia and states the product is not intended for immature animals.
