Here's a little thing I discovered about storing dry foods -- flour, pasta, rice, beans, cereal, grains, etc. I find that many folks down here in hot weather complain about "getting bugs" in their dry foods, most notably flour weevils and beetles. I believe the real truth of this is not that the bugs get into the foods, but that their eggs are in the packaging. Here's how I reached that conclusion: We used to store beans, rice and pasta in rubber-sealed glass containers. They would still acquire the bugs, so that pointed towards them not 'getting' into the foods. We didn't have this problem when we lived in the U.S. --- I think primarily due to cooler temperatures, which were not conducive toward hatching the eggs.
