Yes, it will kill black flies if it contacts them. Will it give control of a black fly infestation? Probably not unless the area is repeatedly sprayed every few hours or used in a misting system such as the Mistaway Mosquito System. This only works in small areas that are confined or fenced in.
Black flies in the woods or in a large area can be impossible to control.
