Here are a link to 3 photos:
These bees were near the back of building.
In addition (in a completely different area of same side of building) there are also some ordinary bees nests (such as wasps nests) underneath the diagonal fascia board near, but near the front of the same side of building. (The building is around 40 feet long from front to back) Do I need to be concerned about the ordinary bees nests if there is no activity seen? Right now I'm more concerned about whether or not the bees in the photos are carpenter bees. What do you think?
