So I did a cutout this weekend, in-the-eve standard hive for many of you I suspect.
11 combs, 2 feet wide 1 foot high. No bee vac that day. But when I got to the last comb, and pulled it, I was able to see that the void space continues back thru some engineered truss work and my smoke drove the darn bees way back there. *Sigh* Couldn't get them. So I went home and finished my bee vac.
Next day I come out and vac up the bees. Boom, done in 30 minutes.
Video of it is here:
But the problem remains, what do you tell the home owner about the forager bees coming home at dusk? How long before they vacate, and how many foragers are there per 10,000 bees?
