Hello .. they sound like drain flies .. these little guys just show up and are really annoying .. they breed in the residue that accumulates in the sink trap and in the drain pipes near the trap .. the grease and stuff there is their environment .. if you get rid of the residue , you will also get rid of the flies ..
thoughts, concerns, please get back to me ..
You could take the trap off the drain pipe and wash it out , and using a rag or bottle brush type brush to clean the sink drain .. or you could also use a product like draino foaming drain snake to clear out the drain ..
