I imagine it is unlikely that they will find a hive if you put one out? I know its impossible to maintain purity with these guys, but how can you improve your chances of getting healthy bees that werent into GM crops and pesticides?
my understanding is that swarms prefer to set up shop where other bees have been before. used, but clean and uncontaminated, hives are a good option. if a new hive is all that's available, I believe there are ways to make it seem like bees have been there before. using some top bars from another hive with a bit of wax or propolis still on them, for example, or placing some lemongrass essential oil in the new hive (I think it was lemongrass, but that could be all wrong).
my experience with swarms has been really rewarding. Jacqueline mentioned that they don't seem to like brushes so she uses a feather. I didn't have a feather around, so I used a branch from a pine tree the bees had been hanging around in. the retired beekeeper that stopped by to help was entirely suited up, but I didn't have any suit so I didn't use one. got stung once when I put my hand on a bee I didn't see sitting on the ladder. I didn't use any sugar water, like the chap in the video recommends, but that could be a good idea as the swarm I moved was prone to scatter when I got involved. I don't think feeding sugar water is a good idea, but a one-time application for this purpose would probably be alright.
in the future, I'm going to try to have empty hives around before swarm season in the hope that swarms will set up shop there without any further intervention from me. that's how we got our first colony entirely on accident, so I know it can work even if it isn't guaranteed to.
