It is my understanding that since the Mosquito Magnet uses a chemical attractant that is specific for mosquitos along with a propane created CO2 emission which simulates human exhaled CO2 I don't believe it would be effective for black flies. In my 1 month of use, I have only seen mosquitos caught in the net trap. You can call mosquito magnet directly and ask them directly.
