I was searching through old messages last night trying to find tips on repelling flies in the coop and ran across a thread where several people mentioned Stall-Dri. Our TSC doesn't carry it and nobody else knows what I'm talking about around here. Is there something similar but under a different name? We tried this: http://www.tractorsupply.com/trap-and-toss-fly-trap-2212108 but it just ends up stinking to high heavens. Our coop has a sand floor and I rake the poop out daily...yes, DAILY. It doesn't smell when you go in there so I don't know why we're having such a bad fly problem. There can be one small pile off poop with hundreds of flies surrounding it. Help! BTW...we use DE. It does nothing to repel the flies.
