I started hanging the Fly Hunter traps in April. We had ZERO flies until the traps were full and i forgot to order new ones in time. The flies were hanging around the full traps and i decided to get the feed store traps until the Hunters got here. Big mistake. They worked, kind of. NOT like the Hunters. So, now we have Flies everywhere!! Please hurry my order!! My horses, and our family, will never use anything but Fly Hunters!!!!
