One of my hives swarmed today around 11:00. I watched them pour out of the hive and form a cloud of cycloning bees. They settled in the ancient walnut next to the driveway about 60 feet up. I did put out small 4 frame nuk box with some frames of old comb, a bit of honey and a few drops of lemon oil then ignored it for most of the day. Around 4:00 I looked out and the sky was full of bees and within 2 minutes they were gone. I think I caught the end of their movement. I walked a quick circle about 100 feet from the tree but no sign of them. The nuk box was of a lot of interest to some other bees but I guess not enough to the new queen.
Worked another extraction this weekend for a local building management company and every time I am on one I learn to be a bit more efficient and wanted to share my list. If there is the opportunity to make a small hole first when starting and extraction this is ideal. So the trick is to annoy the aggressive bees and get them out a small hole and grab them with the vacuum right away. This time around I broke through the drywall with a small hole and kept banging on the ceiling to annoy them. I then opened a hole about 6 inches square. This really helped as the aggressive bees rushed the opening and right into the vacuum. I did get stung on the finger once but was when lifting out some comb and I pinned the bee between my finger and some comb.
It was chilly overcast spring morning when we started. I wanted to get them installed as early in spring as possible to get a full season of sunlight. The next day the sky had cleared and the sun was shining bright on a crisp blue background. I threw the switch on the inverter and powered up the system and the capacitors started to hum.
