Adult drain flies, also called moth flies, are small, moth-like insects (Fig. 1). They typically measure 23 mm (about 0.1”) in length. Adult drain flies are grayish or brownish in color. The wings and body are covered with hair, giving them a furry or fuzzy appearance. The wings are held roof-like over the abdomen. They are weak, erratic fliers, typically flying only a few feet at a time.
