Rober, it sounds like youíve been pretty successful to me! 4 out of 6 swarms isnít bad. You canít win all the time you know
Iíve caught 7 swarms so far this spring and I do one thing differently than you listed. I give the bees a little water by squirting some water into some empty cells. Probably not a big deal and for all I know it might be a completely worthless step, but I am batting 7 for 7 so far this spring. Iíve caught some real beauties so far.
