First one was between the floor joists. Young colony. Pulled the carpet back in a very large room, cut the plywood floor over the joists, removed the bees, and put the floor back in place, carpet back in place.
When I was done, people went back to watching TV.
2nd one was in a soffit about 15' up. The gaps between the brick and vinyl are very small, forcing the bees to enter and exit through very small openings, thus spreading them out a good 5-6' to the left and right of where the colony was located.
It appeared there was more than one colony by how they were so spread out entering and exiting where the hive was located. I thought perhaps as many as three.
