Hospital infestations by the moth fly, Clogmia albipunctata (Diptera: Psychodinae), in Germany.

The moth fly Clogmia albipunctata, formerly a Mediterranean species, is now present in Germany, at latitudes exceeding 53°N. Its synanthropic behaviour allows frequent, year-round infestations in hospital buildings. Hospital infestations have been most common in shower and rest rooms in patient wards, followed by cellar storage rooms, and then rest and shower rooms in hospital kitchens. Preferred breeding sites included hair-clogged sinks in patient shower cubicles, infrequently used toilets and urinals as well as water sources stemming from neglected leaking pipes, suggesting that enhanced hospital water and pest management are necessary for control.
