Size 1/12 inch long. (It is often challenging to recognize flies from a picture. Because different species may need to be treated differently, be sure a fly problem is correctly identified before attempting control.)
Where/when Found indoors, especially in bathrooms, kitchens and other rooms with drains. Can be found at anytime during the year.
Significance The moth fly is primarily a nuisance because it can occur in large numbers. Although it can potentially contaminate food with disease-causing organisms under specific circumstances, it is generally not considered a health problem.
