Start with a clean horse. Curry and brush well to remove loose hair and dirt before applying spray. Be sure to shake the bottle well before each application—the oils sometimes separate from the neem leaf tea. Never store your spray in direct sunlight (even from a barn window), as sunlight will break down the active ingredients. If you are applying spray to your horse before riding, tack up beforehand. If you spray the entire body and then tack up, heat and pressure in the saddle area can cause irritation to the skin. Avoid spraying your horse’s head. Instead, spray the product on a soft cloth and wipe it gently under his eyes—but not above them.
