This species infests virtually any material of plant or vegetable origin, including processed foods as well as nuts, seeds, and legumes, and dried fruits and baked products. It is a major problem in the flour industries, where the larvae create large masses of silk webbing that interferes with machinery and the processes. The female can lay over 600 eggs, usually fastened to a surface containing the food material. They appear to prefer ovipositing on dusty, powdery materials. Typically the life cycle takes about 2 months to complete, and in favorable climates generations can continue all year long.
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.
