The GrainSafe Bag™ is made from flexible UV-resistant Polyvinyl Chloride with a hermetic zipper. It can be installed at home, outside on a leveled concrete, on a pallet, or on a raised platform with rodent guards as well. Its gas-tightness allows insects’ natural breathing process to deplete the available oxygen and replace it with carbon dioxide. This conversion typically occurs within 10 days of storage and kills insects in all life stages. The heavier the infestation, the more rapidly it eliminates.
