You mean like:

Weevils? Had some hatch out in a box of Bisquick a while back. What a gross mess. I guess the eggs are always in flour if it hasn't been baked.

How about make the hardtack round instead of square and store them stacked in small Mason jars to keep out moisture and mold spores?

Or you could just store some Sailor Boy.
