LIving in eastern NC, we deal with high heat and humidity most of the year. It is HARD to keep anything that’s not canned, and even that is not a guarantee.
I envy those of you who live in cooler climes where storing things is easier—not enough to move! :)
I swear, beans and other dry goods come pre-bugged around here! Some things, unless you keep them in the frig or freezer just won’t keep. Same thing with the bean seeds at the garden center, and raw peanuts.
We have the same problems, in my stored dry foods, I use a double plastic, under the jar lid, and put a half dozen of the Bay leaves on top or even in the jar.
Most of the time it works.
Here, we go over a hundred in the summer, and have about half the summer as humid weather, we call it the monsoon season.
