In the meantime, I learned how all of our good honey bees are disappearing. http://news.discovery.com/animals/honey-bees-disappearing-still-a-problem.html. It isn't just the human error causing the problem. But we humans can be part of the solution.
That's why this year, when the bees invaded a space just outside my bedroom window, I called a beekeeeper instead of an exterminator. He removed them all with a safe vacuum cleaner-type of tube and took them to his multi-million bee farm. I felt a lot better about this approach. These are the flowers around my house that the bees favor, sweet and full of nectar. I see many bees again and wonder if they have returned. The mason has already repaired the area where bricks were removed. Hmmm, I wonder if I will have to do this all over again?
