The instructions below are for a simple burlap net that can be used to capture bee swarms so that they could be moved to a hive.
Good Swarm Catcher
I have tested quite a number of swarm catchers, but have found none to give such thorough satisfaction as this simple device which an bee keeper can make. Find a suitable stick and remove the bark; make a ring about 20 inches in diameter out of stout wire, telegraph wire is about right.
Next, take a piece of burlap and sew into bag shape. Then sew the wire ring into the mouth of the bag and fasten it into the crotched sticks so it will swivel and the device is ready for use.
It is well to have on hand one or two poles of different lengths and two short straps, with which to unite them. This device will reach a swarm 30 feet from the ground. It is light and no matter what angle the pole is held the bag is always perpendicular.
To hive a swarm whose queen is at large with the bees, bring the swarm catcher right up under the cluster and give it a sharp jerk upwards and the cluster will drop from the limb right into the mouth of the catcher.
Carry to the hive and invert the bag, or rather turn it inside out, and the bees will drop in front of the hive and run into it and the hiving is done.
