We've used fly predators for about 5 years now and I'm a firm believer in them. We have 4 horses and other livestock chickens and dogs. The fly population is near none. I like to let the chickens out into the horse lot as I think they will peck and hunt through the horse manure to get to any larva. Just have to keep them away from the predators as they love to eat them too
Chickens are very awesome. I wish we had some at my barn where I board. I worked at a Petting Farm kind of place for young children's summer camps as the animal manager, No flies near the chickens! Plus they are such characters, and free eggs are awesome.
I also second the Apple Cider Vinegar comment. Start off with small amounts, cause I know my horse hated the taste at first. Slowly increase it and then they will wolf it down. I've also heard it acts as a blood thinner, which is a bonus.
