First off, Iddee was kind enough to put together the trap-out how-to. I just created the post that link all the sections together. So all credit should go to iddee.
As far as the swarm trap, the farther the better. And obviously, they farther away you go the circumference of the area increases, so additional traps may improve you chances. When the queen decides enough is enough and absconds, it is because of the dearth you artificially credit with you funnel. The queen does not know it is the trap and instincts tells her it is the area, so she most likely will travel a greater distance to try and find a more prosperous area.
Keep us posted and show us some pictures.
Of course - Thanks to Iddee and everyone who's contributed - If it weren't for the Internet and forums like this, and the helpful, knowledgeable people out there - I can't imagine where you would get information on things like trap-outs. I guess it would take years to learn anything.
If I go farther than 100 yards the trap will probably have to actually be inside the woods - is that good? Bad? What you say about the area getting a bad rep makes all kinds of sense though. I know that catching the absconding swarm is low probability. I should probably use a low investment box that I can leave for a long time instead of a hive body full of frames.
