There were two established colonies of honeybees on my new property. One inside the wall, and one in the hollow of the oak tree in our driveway/front yard. I had the ones in the wall relocated to a community garden. I called a beekeeper about the ones in the tree because I was constantly crossing paths with them and they had even flown inside our cars and home several times. I was told that most likely the bees would move on eventually if they did not die or go dormant in the winter. We had a really sudden burst of cold weather and I thought the bees were gone so I took some advice of the web and filled the hole with expanding foam. Almost two weeks later, I went to remove the excess foam and cover the hole with something decorative. Much to my suprise I heard the bees buzzing inside!! I put my hand on the foam and I could feel the vibration. Now, I can hear the foam crackling and I'm most certain that the bees are in the process of gnawing their way out. What I am afraid of, is that they will escape in an extremely aggitated state. They are VERY close to my frount door. I have two infants. I am afraid of what will happen if they get out. Can anyone give me advice or ease my worried mind? I tried to educate myself and do the best I could, but now I am in trouble. Thanks in advance. -B-
