Sorry for the delay, didn't see your question!
I confess mine are all confiscated from poachers. I live on a wildlife preserve that's part of Quality Deer Management Area. My farm is the designated sanctuary area (no hunting of any kind) for the co-op. Sanctuaries are specific areas which provide good cover, water, natural feeding and bedding areas to lower the animals' stress. There are always well-marked boundaries and responsible hunters know better than to hunt in the sanctuary area, even though there is lots of game here.
But from time to time, some dope pushes his luck and sneaks in and mounts a tree stand high up in a tree. The things is that I walk my land all the time and I usually discover the stand, and remove it. If they have not injured the tree, I will usually let them have it back (after I give them a piece of my mind.). But if they have also driven spikes up into the tree to use as footholds and cut off branches so they could have a better sight lines, the tree stand is mine. I take serious exception to damaging trees in my woodlot.
If you google portable tree stand, you'll see how they work. I think they cost between $50-125. Some have little rope ladders that you could climb to check on the swarm box (not to carry it back down - you'd have to lower it by rope. ) I don't have any of those because that kind doesn't require the user to put spikes in the tree to get to it, so I'll give them back. My fave one is a Cabela's model, but they have them at Dick's, too, probably for a lot less money. I don't leave them up year round because I don't want to girdle the tree with the straps.
A tree stand would allow you move the swarm trap site, without harming the tree at all. Sometimes it takes awhile to find the magic tree that seems to collect swarms more often. Sort like an ultra-violet flashing sign that says, Yunzow's Famous Bee Motel, with the bee equivalent of free wi-fi, a complimentary all you can eat breakfast and a great ocean-front view.
