I have tried the swarm lures from Brushy Mtn
But have yet to get a swarm to go into a swarm box with or without them
the bees preferring trees and such. (good thing I own a 40ft ladder)
The pheremone lures work on the same principal as was noticed in ancient
Greece with rubbing a hive with bee balm (not monarda)
but m. officianalis to attract the bees.
They are cheap enough to fool around with though so I am still
experimenting with them.
I am convinced the bees are more concerned with box volume and siting
though
