Too late again! To do what, I don't know, and not really too "late", but got out there just as they were leaving the box.
But not too late to try my lemongrass theory. As they were filling the air more and more, I noticed they were starting to land on the pear tree, most likely the area I heard the previous swarm take off from. They were starting to gather about six feet up on a thick branch. That was not convenient for me. The apple tree nearby would be better. So, I started blowing across the lemongrass oil and noticed the flying swarm seemed to move closer to me. I picked a branch I thought was convenient on the tree and rubbed lemongrass oil on it, and blew some more. For awhile, I thought they were going to cluster on my hands! I thought maybe I should have some fear, standing in the midst of thousands of stinging insects, but instead, that was great fun! Bees were landing on my hands, my glasses, and I had no fear.
I rubbed some more oil on the apple tree, blew some more, but noticed there was a cluster starting on the pear tree. That wasn't good. So I went up and vigorously shook the tree, blew on the bees to dislodge them, and went back to the apple tree to blow more across the oil. Shook the tree some more, and had the thought occur to me that that may not be the wisest thing to do. Maybe my imagination, but a bee seemed to show more than a little curiosity to my face. I walked over to the apple tree, and after awhile went back and shook the pear tree again. This time, I'm pretty sure a bee was trying to tell me, 'Didn't we tell you that was enough?'. It flew quite a bit in front of my face, followed me a ways, was in my face again, followed me another 50 ft. where I weaved between the trees, and then found me again. Ok, enough fun, I decided.
Anyway, after I felt safe enough to venture back to the apple tree, there they were on the branch I picked out for them. Every once in awhile, a bee seemed to fly near me, but not aggressively.
So leaving multiple queen cells in each group did not prove a good thing this time. There are others in the other box. What advice should I do now if there are still multiple cells in the boxes?
