Oh no! ugh! Bug infestation is the worst! I just bought 10 for $10 oatmeal, I better get it in the freezer for a couple weeks before tranferring them into better containers.
I had a similar problem a while back...I put cereal, flour, sugar, everything like that in Tupperware and Rubbermaid containers. Sonde like you got the best of the buggers...bit still..anything you “open” and then store...put in plastic.
The wedding ring story is so blatant and “in your face” so that’s why I think it’s true (putting on my foil bonnet once again!)
