Once I realised that there were moths happily dancing outside my window, just dieing to come in, and that I was bringing moths in from the outside with all kinds of food, I stopped blaming myself for not having cleaned up enough and not having kept everything in appropriate containers - I *had done* my part, but they still came in from the outside.

I get the occasional one here - and I meet the occasional one outside - so while I still keep everything double-wrapped out of habit, I'm also aware that I might, at some point, have to deal with another infestation.
