Re: My first hive moved my swarm in this evening
As you have a top bar hive (no frames), rubber bands may be difficult to use. Alternatives include bending some fence wire into a U, then hooking one leg of the sideways U over the top bar and pressing the other leg into the comb, or making a sort of a basket suspended from the top bar with 2" chicken wire.
