Here on the Donkey Whisperer Farm we do not have a fly problem as we use fly predators and we compost two times a day, ensuring to keep the compost a ways away from the pasture and paddock. Compost turns into black gold for the garden.
I suggest trying the fringe fly mask as this one does not go over the ears and is Not too hot 🙂

I would never put this on my equine too hot and claustrophobic
GOD bless you and your family two and four-legged!
