You can setup a trap-out. Much the same as I did at the last part of this video:
I tried smoking them out, but that didn’t work like I thought it would. Once you set the trap-out up early one morning, put the frame of brood as close as possible to the entrance the bees normally use. After a couple of hours, when the frame is covered in bees, gently place it into a brood box. Then place the brood box as close as possible to that entrance, leaving the lid partly open. The important thing to do is to make sure that all other possible entries are blocked. Fresh silicone will mask any bee odor around where you fix the trap-out, as well as any other place the bees try to get back inside through. The bees wont get stuck in the silicone before it sets, they’ll just keep away from it. The thing to monitor is that bees don’t block the funnel exit. As well as make sure bees don’t start returning into it.
PS, thank you @Peter48, cheers
PPS, at the time of making this video, I didn’t realize how effective silicone was at masking bee pheromones. I could have used it where the wooden square meets the cable drum.
