Waldemar wonders if  using pollen traps delays or prevents swarming.

A properly constructed pollen trap allows drones to exit.  While I have seen
more than one design that does not allow for drones to exit, I am certain
the result is a dying mass of decomposing drones.  UGH!  That same exit will
allow the quees to swarm.

I do not believe a properly designed pollen trap will have any effect, good
or bad, on swarming.
