“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.”

Susceptibility of Tribolium castaneum and Trogoderma variabile larvae
and adults exposed to ProvisionGard™ treated woven packaging material
Journal of Stored Products Research, 15 August 2017
“This study has shown the effectiveness of [treated] polymer packaging against T. castaneum and T. variable. Exposure of various life stages of both insect species on the treated packaging produced lethal and sub-lethal effects. Packaging treatments could be used as a preventive method to help manage stored-product insects in facilities where bagged and packaged food products are stored. Further experiments can be done to evaluate different [treated] packaging materials to assess efficacy on stored-product insects that were not evaluated in this study.”

Effect of ProvisionGard™ treated polymer packaging on fecundity, egg
hatchability, and egg-to-adult emergence of Tribolium castaneum and
Journal of Stored Products Research, 18 July 2016
“Packaged foods face many challenges before they are finally consumed. These include package flaws during manufacture, improper handling during shipment, inadequate storage conditions, lack of proper product rotation, and improper sealing in the home. Increased restrictions on pesticide use and emphasis placed on sanitation may be somewhat hindered by demanding production schedules, so the development of insect-resistant packaging is of increasing importance to both the consumer and the manufacturer. The consumer is assured of insect-free food, and the manufacturer is protected against loss of goodwill and lawsuits arising from insect infestations in consumer-sized packaging. Future research in this area will lead to the development of more effective packaging methods to ensure that packaged foods remain insect-free until consumed.”

A new technology in pest management is an insect resistant packaging that is US EPA approved and FDA compliant for all types of food, feed, and seed packaging. ProvisionGard was designed to protect commodity for over one year from stored product insects and can be implemented easily at current packaging suppliers for pennies per bag. Designed for paper/woven bags and super sacks, it requires no labeling and safely reduces insect populations in and around your stored products. The following study demonstrates efficacy using common stored grain beetles.
Studies are being conducted by the USDA-ARS and ProvisionGard Technologies to evaluate residual efficacy of packaging material with the insect growth regulator [treatment] incorporated into the laminate exterior of bag packaging.
Materials and Methods
Experimental units for beetles consisted of either the inside or outside of untreated or treated bags placed in the bottom of a 62 cm2 Petri dish (10 mm high), and sealed by caulking around the edges. Ten larvae of either beetle species were placed in an experimental dish, and there were 6 replicates for the inside and outside of the bags for both the treated bags and the untreated control bags. The criterion for assessment was the emergence of morphologically normal adults of all species. [Treatment] can cause physical deformities in insects (like twisted wings and missing segments).
Treated bags and also companion untreated bags were tested by the USDA ARS in Manhattan, KS. [Treated] residual tests on bags were conducted to measure efficacy. Test
insect species are 4-week old larvae of the red flour beetle (RFB) and the same age larvae of the confused flour beetle (CFB).
The outside and the inside of the treated bags showed activity of the red flour beetle larvae and the confused flour beetle larvae in the time trials. No adult RFB emerged from the larvae that were exposed on the treated packaging. There was some emergence of normal adult CFB from larvae exposed on the inside and outside of the bags. This is consistent with previous tests with [treatment] that indicate that the CFB is less affected compared to the RFB.
