Traveler doesn't like the fly sprayer, especially around his head and eyes. I can't blame him, I don't think I'd care for someone pointing and spraying some unknown liquid around my face, either. Unfortunately, it's something that has to be done, so he tolerates. I have a couple of products I like to use for keeping the flies at bay.
Early in the fly season when it's not so hot and the flies haven't begun their relentless attacks on Traveler's eyes, ears and body, I like the Bronco Equine Fly Spray plus Citronella Scent . It's a non-oily fly repellent product I can use everyday. Since he doesn't like the sprayer around his head, I can spray a little on a soft rag and wipe his ears (inside and out), his forehead, and avoid getting too close to his eyes.
In lieu of using the spray around his head, I use Swat Fly Repellent Ointment , too. This repellent is a clear or pink ointment easily applied around eyes and ears. I've also used it on healing surface cuts and abraisons to keep flies from infecting the area.
Best product I found for use during the hot, hot summer months is Endure Sweat-Resistant Fly Spray for Horses . It will create a repellent barrier for up to fourteen days even when it's wet and the horse is sweating. This reduces the need to spray everyday. It also provides repellency and a quick knock down of mosquitoes. Mosquitoes are pests no horse owner wants to have around.
