Because the honeybee cannot be distinguished from its native cousins without detailed scientific measurements, any honeybee nest or swarm should be respected at a safe distance. Only experienced beekeepers and/or pest management professionals should be contacted to deal with colonies or swarms of honeybees. Never attempt to treat such nests without the proper training and equipment.
Once the colony inside a wall or attic has been eliminated, the building owner will need to open the wall and remove all the honey and honeycomb. If not removed, the honey will rot, produce strong odors and seeping stains, and will attract other insect pests.
