Unfortunately, there are no good answers for black fly because they are not attracted to fly traps or fly baits and there is no way to stop the larva from developing. You may want to check in with your local department of agriculture to see if they have any advice for you.
The insecticides (Bifen IT, Tekko Pro & ExciteR) in the Mosquito Control Kit - Professional may only provide partial control for black flies if applications are made where you see the flies land. The residual insecticide in the Mosquito Control Kit, Bifen IT however is labeled for biting flies, house flies, gnats, mosquitos, and many other insects. It is a great general purpose outdoor insecticide to use mixed at 1 fl oz per gallon of water per 1,000 sq ft. Please view the product label here for more information.
