Yes, Tempo SC Ultra is labeled for attic flies (cluster flies). If you are dealing with a heavy infestation, we would recommend using 16 mL per gallon of water. If it a light infestation, you will use 8 mL per gallon of water. You will apply this to places where the attic flies have been seen or found. You will Tempo SC Ultra as a crack and crevice treatment. Please let us know if you have any additional questions.
