All dried grain products come with beetle and weevil eggs included. This includes rice, beans, meals and flours. View packages of this stuff as ticking time bombs.

Your storage technique should address preventing the eggs from hatching.

Freezing or refrigerating does it. So does vacuum packaging. But once out of the refrigerator or vacuum pack, all bets are off.

Desiccating it with a gel pack in a glass jar will not (despite the advertising from the guy selling gel packs). There is enough moisture in dried grains to sustain a zillion weevils. A gel pack isn't going to reduce the moisture enough to matter. Put beans in a jar with a gel pack and the flour beetles will hatch and eat the beans before you do.

Simply putting the stuff into a sealed glass jar will keep out the mice and insects that are nosing around, but the insect eggs will still hatch. Once they hatch in one package, their children will quickly locate the rest of your stuff. All glass will do is contain the infestation to one jar.
