Thomas D. Seeley did a number of experiments to determine how a swarm chooses a site and came to the conclusion that bees prefer a nest entrance that is rather small, faces south, is high off the ground, and opens into the bottom of the nest cavity. His excellent book, Honeybee Democracy, goes into great detail on how he came to these conclusions, and I would highly recommend it to anyone interested in learning more about the decision making processes in a hive.
With all that being said, sometimes a swarm will choose a location that goes against those basic tenets. I give you Exhibit A:
This hive is underground in one of the large green boxes that contain the water cutoff valves for either a sprinkler system or the water line entering your home.
I was initially sent this photo of a bunch of bees on the ground that was causing some concern.
Fallen leaves were completely covering the entrance, and I had to remove a rather thick layer of leaves to reveal what is shown in the video. I did not try and remove the cover as it most likely was lined with comb, and my intention of this first visit was to properly assess the situation. Luckily, the bees were not aggressive even after raking away the leaves and dirt covering the entrance. I had one or two guard bees give me a buzz but other than that, they were rather nonplussed with the whole situation.
My next step is to reach out to some fellow beekeepers to see who would be interested in removing this hive. I personally don’t do bee removals as I really don’t have the special equipment or apiary space to relocate these feral hives. I’ve seen hives in some interesting places, but this is the first time I’ve personally witnessed a hive located underground. I’ll hopefully be posting an update soon on the successful removal of this hive.
