To help your fly spray do its work of keeping biting insects away from your horse, follow these guidelines:
Start with a clean horse. Curry and brush well to remove loose hair and dirt before applying repellent. Be sure to shake the bottle well before each application—the oils sometimes separate from the neem leaf tea. Never store your fly spray in direct sunlight (even from a barn window), as sunlight will break down the active ingredients. If you are applying insect repellent to your horse before riding, tack up beforehand. If you spray his 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. For extra protection to the ears , gently massage inside the ears.
