You are correct, but that is for an established hive. Yes, that's me in the video. A frame of brood and/or honey would help attract them, but they may just move the honey back into the structure before the queen comes out. If you could install a cone and a frame of brood and honey, and give them an exit, you would have the best chance of success. You could likely finish it within a few days, whereas established hive takes 6 to 12 weeks.
