Regarding my results with your Resolve spray product. The beautiful quarter horse we adopted, came to us with lots of underside irritation from gnat and fly bites, from a few months prior to us getting him. Once here, he constantly chewed and bit his belly and groin area and scratched with his hooves. We were concerned about further injury he would cause. After only three applications, spaced every other day, the itching and constant biting ceased. We’re fortunate that this horse had been handled and groomed extensively and took no issue with being sprayed.
