Drain flies breed in polluted shallow water. Since these flies often originate from filthy conditions, there is a possibility of disease transmission.

Control measure:
The key to solving a drain fly problem is to eliminate the build-up of organic debris. Areas that are likely to be a source of the fly infestation include damaged or faulty septic lines, areas where rain water pools or toilets (particularly if they are not used frequently), sinks and bathtubs and loose ceramic floor tiles.

Aerosol sprays of pyrethrins (or other flying insect sprays) will kill adult flies, giving temporary control, but they are not a real fix for the problem if you do not fix the source of the flies.
