The larvae are dirty white with a dark brown head (Forbes 1923). As in Plodia interpunctella, they live in a silken gallery in their food source. Once an infestation is discovered, the affected food source should be discarded and the area cleaned up. Freezing food products suspected of containing larvae is a good idea. The adults are said to fly at night (Goater 1986).
Conservation A common pest (Covell 1984), of no conservation concern. Diet Info Larvae feed on flour and stored grain. Range Worldwide. Reported from many areas in Alberta by Bowman (1951). This moth has been found in most homes in Alberta.
