After we moved into our flat nearly ten years ago, we noticed loads of moths. The small, gold-coloured ones. They mostly seemed to be coming out of the carpet in the bathroom. We cleaned up and got rid of all the carpet but all this time later, around this time of year, some more pop out, these are presumably the descendants of those first moths. They are a very tenacious beast.
As I have entitled this as a chat thread, it would be good if you posted a related anecdote, to make it a bona fide chat.
