A very interesting thought. Where do those little beetle bugs come from? I store all my flours, etc., in airtight jars. But every once in awhile, I'll go to one that I haven't used in awhile and whalah...little bugs.
Do they just appear out of thin air?
I'm getting ready to go and get my jar of semolina flour...rainy day great for making homemade pasta. To bug or not to bug?
