We have been fighting with weevils in our pantry cabinet for some time. daisy_knotwise and I thought we had eradicated them, but apparently not. Thus, Gretchen started and I finished cleaning out the infested cabinet with a strong predisposition to "If in doubt, throw it out."
We threw out a lot, including a lot of expired canned goods that had accumulated since the last purge.
The cabinet is now clean and has many vacant spaces on the shelves.
