I cut the end of wood paint roller handle to get the threads. I glued in the center of a plywood disk and screwed it to the bottom of a bucket. I have a string that runs up the pole, through the disk and holds the lid and with a pull flips it in place. I simply give the swarm a jab with the setup and pull the string. My bucket is well vented so I can leave them in it to take home or pour them into an ready hive body in the back of the truck.
