drain flies. If you want to discover if these are coming via the inside of your home, cover the drain opening during a down time with a clear plastic container that has one or more glue boards taped to the sides. Leave in place overnight or for a few days to catch flies.
If outside, this drain fly or similar species usually breed in standing water. There aren't great options to manage them due to our wet summer climate. You can continue cleaning off the affected areas with wet rags or a shop vac to remove the flies. Unless you can eliminate standing water, it's not practical to try other methods of control.
