Is it just me or are others going through the misery of yellow fly bites. If I step outside,even with repellent on, it's like I have a flashing neon sign on that says" here comes mealtime". I have tried every so called remedy to get some relief-- sliced onion rub, meat tenderizer,windex because it is mostly ammonia, calamine lotion.What preventitive or remedy does anyone else use and do the flies leave after a few weeks?
