I know there are several products out there for feed through fly control. I was curious to what others have used and how well they do, or don't like the products.
Also there are a lot of spray on fly-sprays, what ones do you like, and dislike?
Another one I have heard of, but not used is adding Garlic powder to their feed. Anyone else done this or heard of it?
What about the Apple Cider Vinegar?
