Yes, Tempo SC Ultra will kill flies. Please make sure to pay close attention to entry points and areas that contain moisture (undersides of leaves, bathroom, laundry room). Also, spray outdoors around the perimeter of your home 2-3 feet up and out. It is a residual product that can take a few day to start killing insects. If the infestation of flies is extensive then you may treat again after 7-14 days. For more information on fly control, please read our article on How to Get Rid of Flies
