If you don't want to put it in the freezer, use a more solid storage
container in your cabinet...either something like tupperware, glass, or
metal. I recycle my mayo jars, wash them and fill them with rice and
grains, same thing with using metal coffee cans to store anything that
can get pantry moths. Buying your rice in bags will help you see it
once it's too late, but preventing them from getting in works better
for me!!
