A deep box is about the right size for a large swarm. I have a bunch of deep nucs but the large swarms won't use them.
Place one frame of old drawn comb in the box and fill the box with empty frames that have a thin strip of wood in the top slot, popsicle sticks will do.
Get a small jar of Lemon Grass Oil, put a drop of it on a q-tip, wipe it around the entrance, put the q-tip in a small baggy, seal it and drop it in the bottom of the box.
Set the hive about 6-8 feet of of the ground.
Good luck.
