Pro tip: buy some snack-sized ziplock bags, measure out what you need for a serving, portion it into a ton of individual bags, and keep those in a sealed 5-gallon buckets. There’s a type of beetle that lays its eggs in rice, and it may not hatch until after you’ve bought it. Then they propagate, and there are tiny beetles all over the batch… and losing the better part of a 50lb bag to those fuckers is pretty heart breaking. If you portion it out first, and then it hatches, you lose a single-portion ziplock full. No biggie. Also keep the empty ziplocks and reuse them for the next big bag of rice.

Do this, but also Freeze 'em.

The beetles you’re talking about are common in pretty much every grain. Freezing kills the beetles, the larvae, and the eggs. I’d suggest gallon-sized freezer bags rather than snack sized. If you don’t need the space for anything else, just store the bags in the freezer. If you do need the space, freeze the bags for a week, then move them to the buckets.

Same trick works for flour, oats, etc. Any grains you bring home should go straight into the freezer for a week before you move them to the pantry.

An additional benefit: Freezers are most efficient when they are kept completely full. The thermal mass and insulation of 50lbs of rice and/or other grains will keep your perishables frozen for days during a power outage.
