This is a general feeder that may attack a wide variety of structural materials, including stored food products, fabrics of animal hair origin, dried plant materials, book bindings, paper, seeds and grains, corks, and leather or animal skins. It may feed on accumulations of dead insects, and this highly omnivorous behavior of the larvae makes it difficult to isolate an infestation. This is the only species in its genus. It is believed to be native to Asia, but is now found throughout the world including most of North America, transported by human activity in infested foods and other materials. In nature there will usually be a single generation per year, but in warm, humid environments within a structure the life cycle may be completed in as little as 7 months.
As with all pests of stored foods or fabrics it is necessary to find the source where the larvae are feeding and developing. Once this is discovered and disposed of a thorough cleaning of the area will remove debris and wandering larvae and an application of a residual contact insecticide can be made to intercept others that may be in the area. Adult moths can be killed with a vacuum cleaner or a light mist of pyrethrum.
