2 cases or thereabouts.

25 quart jars ."A pint is a pound the world around."

A pint of rice weights 12-14 oz depending on various factors. Vacuum seal the jars if you want them to last.

I am going to put rice in quart mason jars and store it.

Alternatively, you could buy a couple of 5 gallon plastic buckets with gasketed lids, and fit it all into them (probably with room to spare). Won't break if knocked into.

If you're worried about the plastic being food-safe (e.g., if the buckets are used and you're not sure what the buckets contained), you could add an inner liner bag.

If you're worried about not getting a vacuum in the jars, toss a chunk of dry-ice into the top of each bucket before pressing down on the lids to seal them. It'll sublimate into CO2, which is inert.

If you want some easier-to-access storage too, you could mix it up. One bucket for long-term storage, and a bunch of jars for short-term.

Can't you just put your rice in sealable plastic or glass containers and include a couple Bay leaves in each? The Bay leaves will deter any "creatures" from invading. I would think that sealed Mason jars would do the same with no problems for months. I've kept rice for a couple years in just plastic containers. But, then, I'm not an expert! I also sprinkle dried garlic on my cupboard shelves to keep those "flying" thingies away.
