Here is an update on my swarm situation. The hive on the neighbors roof has two mostly filled frames of honey. Additionally, I put some lemongrass essential oil on the top bars of some of the frames, on the bottom board, both inside and on the runway. A few bees went into the hive and a few would fly around the area.
I went out a little bit ago, and the swarm seems to be missing from the tall pine tree. Looking with binoculars I can see some bees flying around where it used to be, but no sign of the swarm itself. Could the swarm have left, and these are scout bees left behind? I didin't notice any swarm activity in the air, but it does seem that there are more bees going in and out of the original hive. Could they have come back? I forgot to count the number of bees remaining yesterday when I did my post-swarm inspection, so counting them now would be pointless... Could the swarm have moved to another part of the tree that I can't see? I can't imagine why they would do that after spending the night in light wind and a few sprinkles. What do you all think is going on here?? If they have returned, I am thinking of spliting the hive..it this a good idea?
