Pretty much both. I didn't catch much but booklice and had fewer than usual. Otherwise those traps were pretty clean pre-pandemic through post-return. We run a tight ship, though we do tend to have booklice and mites (for some odd reason).
The more I think about it, the more I think that human activity also disturbs things, and so during the work-from-home phase not much was moved around, so booklice tended to stay put.
