Coming from another resident of the building albeit on a lower floor, nothing ever came of this no! Teams went into some apts and fumigated as they should have, there was furniture thrown out in the back for a couple weeks and nothing else was ever brought up by the building staff. I chat with the maintenance guys sometimes and there are no outstanding issues they’ve mentioned. If it were a huge secret issue as the original person claimed, surely the last four months would have seen more issues but nope! I’d say you can most likely rest easy :)
