Over the past year, we have bought extra supplies of dry beans, peas, blackeyed peas, and rice. They have been stored up to now, in ziplock bags in the pantry. This morning, we discovered lots of ??? in the beans. Appears like sawdust. In the rice, we have a few small like looking moths. All appear to be deceased, but they are still there. In checking the various methods of getting rid of these pests, most information states "find and eliminate the source, and throw out the infected grains". Since we have quite a bit already stored, we are thinking of putting them in the oven for 30 minutes at 130 degrees, as one source recommended, then sealing them into vacuum packed bags, rather than zip lock. Another said to freeze them for 4 days at zero degrees. We do not want to throw it out. All suggestions appreciated.
