For the past two weeks, I have had on my beach, Rotten Turnips, Two Tires, Rusty Parts, Old Can, and a Moldy Shirt, and I still cannot get a fly. I have constant ants but not one fly. The items on the beach have enough clearance from each other and any rocks and things. Also, I have not touched or disturbed them. Does anyone have any idea how to get a fly to appear? Thanks in advance.
