This was our first year using Spalding's fly predators. I have to say I was very surprised with the results. We only used a fraction of the fly traps, and sticks that we were using. It cut the fly spray expense for the horses from 5 bottles down to 2.
I think finding the correct application is the key to success. I realized after they sent the double shipment in July, that I probably should have been using larger shipments all along or at least doubling up in June, July & August. Going to look at that when I sign up for next year.
