We live in Texas and the flies are AWFUL in our barn. I know they are attracted to feed and manure but both of those things are unavoidable when raising livestock. We clean stalls and dump the poop everyday - granted, the manure is dumped outside of our barn, probable 100 yards away or so (we use a wheel barrow so we can't go very far). I've tried fly traps, sprays, fly predators, bait, etc and nothing helps - there are so many of them!! Is this something I can call a pest control company to help with? I'm looking for any and all advice that anyone has. I have visited a few other places and their barns do not have near the amount of flies that we do - I've asked what they do, I try it, and it doesn't work. I know it's about to cool off and that will help but I still would like to figure this out once and for all!
