While Cyper WP will kill any house flies that land on a surface that has been treated with it, there are some other products that may be better for your situation. Can you please tell us where you are trying to control the fly problem and what kind of property you have (ie: home, business, farm)? We may be able to give a more specific solution to your fly problem knowing more about your situation.
