I have found however that bees in a TBH rarely if ever need to be smoked.
Something you can try though if you need to smoke because you have agressive bees is something they do in africa with scuts there in tbhs. They hang an open can smoker from a nail directly below the hive entrance, the bees working to keep the smoke out of the hive have less time to deal with the beekeeper. They are more concerned about the potential fire.
It seems to work without actually smoking the hive, its just a drifting smoke that the bees constantly fan away from the hive.
