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.
