That's what the Apiary in LV is for.
Well the greenhouse needs them for sure, believe it the flowers and pollen attracting . There are plenty of them too, heard from another post that if there too many some sort of glitching starts so I have been harvesting then bringing to the apirary at Lakeview.Laslo451 (talk) 22:12, December 10, 2013 (UTC)
The apiary is a disappointment: never more than five bees;Â and if I take one, it does not respawn anytime soon.
The apiary is mostly gimmick. If you need bees here's a list of locations where you can find some.
