“Current methods employed by food manufacturers and warehouse facilities to control  stored-product insects include stock rotation, fumigation, contact insecticides, and aerosol applications. These pest management techniques used singly may not be enough to prevent infestations or control populations of stored-product insects in manufacturing facilities, warehouses, distribution centers, or retail environments. However, a multi-pronged approach to pest management which incorporates practices such as sanitation, trapping, aerosol applications, and IGR-treated packaging may provide an unsuitable environment for stored-product insect populations. The [treated] packaging used in this study could be used in conjunction with existing pest management programs to prevent stored-product insect infestations in packaged foods as part of an integrated pest management program. Continual exposure …through an entire life cycle resulted in zero normal adult beetles…The results of this study indicate that this new packaging technology appears to be cost affective during long storage periods, which would occur during storage in warehouses, distribution centers, and retail stores where packaged products could be stored for weeks to months before they are moved, shipped, or bought. The [treated] packaging would be a valuable asset to protect such packaged products over time. [Treated] packaging has shown promise to be a method for protecting food products, and further testing is warranted.”
