This is quite common with BBQs. Congrats on not taking to them with the fly spray like a lot of people do.
Id hit em with the smoke at noon, move the comb into a box, move the box into the cupboard and them remove the box box from the BBQ next noon, hide the BBQ, leave the box. Put the box into a hive next day, or skip all that. Smoke em at noon, dump em all into an empty super, comb an all, with a super of frames on top. Move this hive to where you want it and ditch the BBQ from where it was.
As long as you get the queen and dont kill her, you got a working hive.
BUT I AM NO EXPERT!
