Recently I removed a swarm from a barn using a bee-vac. Upon filling the
first box,the bees were active but there was nothing unusal.Upon vacuming
the second and third box, the bees were busier, fanning heavily and were
producing a pheromone that was sort of a sweet floral smell. Also there were
drones fling back and forth quite excited. As I didn't see the queen I
assume I vacumed here up but I don't know which box as they were quite full.
Does anyone know what the scent they were producing was ? Has anyone else
had a similar experience ? This is my second swarm using a bee-vac so this
was new to me.
