Happened to me too (first liar doesn't get a chance),,,
In my case it was in the family room near the chimney (in the ceiling). When the beekeeper came out, he first took IR scans of the ceiling to see where they were. After that, he cut the ceiling open and vacuumed up the bees (he had a specialized vacuum container). Then he took out the hive, which looked like it was a work in progress for a while (years?).
Yes, I have pictures of the hive, after the bee removal, before the hive removal. Quite a complex construction if you ask me.
