Heads up to you that store grain at the brewhouse, I had to toss 2 bins of my grain on Saturday due to a pantry moth infestation. I also noticed a bunch of em on our fly paper.
If you store in air tight containers, you are probably fine, but if you store in an average storage bin like mine you are probably infested.
What qualifies as "average storage bin"? I can't say I know anything about these moths. I've got homer buckets with those twist-on lids—those should be fine, right?
If you're talking about the gamma lids, your stuff is safe. I would think even the regular orange home depot lids are fine since they have a rubber gasket.
Homer buckets are probably fine. I had those cheap storage bins ya get at Target for five bucks.
I did notice today that there are a few shelves with my style of cheap storage bins. Your grain is probably infested.
