I have an experimental bait hive that I am trying out. Came from a suggestion from an old fella who said it worked every time for him.
Take one of the plastic four gallon milk crates
Insert cardboard to cover the insides of the crate entirely. (I plan to use 1/4 in luan instead, cardboard melts in the rain...yuck)
Toward the bottom of one of the sides, cut a smallish (roughly 1 inch diameter) hole
Toss some old comb inside.
Cover the whole thing with a piece of board that covers the entire top, secure it to the crate with a couple straps or some twine.
Place it where you suspect it will get attention, on a tree, wherever
After you find a swarm has taken up residence, you can cover the hole and move it to where the new hive is.
Take the lid off, they likely have started building comb on the bottom of it.
This fella used the shake down approach of emptying the box in front of the new hive
You can try to save the comb and affix it to frames.
I am collecting milk crates over the winter to give about 10 of them a test in the spring.
Let you know how they do.
