You can't beat a swarm at a workable height - I've had a few that needed an engineer to get at - lol. The worse was about a 8 pound swarm, up 40+ feet in a locust tree in a dense wooded area across from my house. I rigged up a sheet of plastic in a cone shap with a hole in the middle and a bucket uner it to catch them.
Then had to lasso the branch with a clothes line, yank it and it took three trips to catch the majority of bees. Each time I would cover the bucket with the lid to keep as many as possible in or transfer them to a sealed hivebox in my yard, but half got away each time on me.
I figured out later, I needed a modified swarm catching bucket - a rubber bladder built into the lid, so the weight of the falling bees would trip open the bladder and allow the bees in, but pop-back-up to keep them in, and a corked hole on the bottom to allow them to walk into the inner cover when I was done.
Once the queen was caught (try three) I finally had control of the swarm, but until then I was taking two steps forward and one step back.
Most of my swarms though http://www.beemaster.com/honeybee/swarms.html
have been low enough to rangle perdy easy. I was just realizing that 3 of the photos on this page made it to the Beekeeping for Dummies book.
Sounds like you are gonna be busy all Summer if you have that busy of a Spring - curious how HIGH you plan to build - I've only had one hive ever to make it 5 supers, or if you are gonna build out with more colonies?
