The larvae are not serious pests in general, but they do infest stored food products such as a variety of seeds and grains as well as processed vegetable-based foods. They may also attack tobacco and have been found burrowing into corks in wine bottles. The life cycle can be completed in less than 6 months, and there often will be two generations per year in indoor infestations.
Typical of most stored food moth infestations, an inspection must be made to determine which materials are infested, including areas of the structure where foods may not typically be found, such as garages or closets. Disposal of the infested material, followed by a thorough cleaning of the area and possible application of a residual insecticide to intercept any larvae that may have left the food material are needed.
