Consider Your Fly Control Timing

According to NDSU Extension Veterinarian Gerald Stokka, it is important to pay attention to cattle to know when to utilize fly control. “Cattle suffer the most when they are bunched up under shade. You can do something to alleviate some of that fly population.” Fly control timing is vital to avoid resistance. The longer flies are exposed to a control product, the easier it is to create resistance. “Typically, flies become a problem in late June to July, certainly in August; If you can put off some of those strategies for actual application, those products have a greater chance of working better.”
