I’ve had pantry moths before, and I defeated them for some years through cleaning and improved storage: nothing grain-like in any unsealed container. The sealed containers have included ziplocs, Mason jars with canning-type rings and lids, heavy Rubbermaid containers, and of course original sealed plastic bags from the store.
It’s this last that was my downfall, I think. Of course the moth eggs come in the package. Today I think I found the central hive, so to speak: a big bag of jasmine brown rice that turned out (the squeamish should probably just bail, now) to have about as many worms as grains of rice. They look remarkably alike, too.
From this “sealed” bag or elsewhere, the moths have gotten the upper hand again and are flying around the cabinets. So I did an incredibly thorough clean-and-inspect, hardly looking at a sealed Mason jar full of brown rice because what could be better sealed than that? But a tiny bit of the rice seemed to be clumped, so I took off the lid and seal, looked very close, and… there were worms on the rim of the jar, just on the outside of the rubber seal of the lid, under the ring.
I feel rather defeated. If a sealed Mason jar is not good enough, I don’t know what I can use to store grains. Curious to me that the worm was outside the rubber seal, but I can’t tell for sure if it started off on the outside and never made it in, or if it started on the inside, heroically breached the seal, then promptly died of the effort.
At any rate I’m ready to just burn the place down and never look back.
Short of this, tell me about food storage systems that will defeat these horrible things. Before I discovered the Mason jar inhabitant, I was experimenting with a small Rubbermaid container filled with water, and found that it leaked. Oh well, I thought, just get glass jars with sealed lids for everything. Apparently not good enough.
Still short of burning the place down, what about giving all new grains from the grocery a short trip in a 250F oven, in open glass jars, before cooling, sealing and putting on the shelf?
