Here we are discussing how to go and pick a feral hive and bring it to yard. After my experience it is really difficult job, and pleasure not at all.
Often bees are in difficult place. When you go and broke their hive, they don't like it at all. When you start to smash combs, bees mostly became mad. They attach inside the smoker and soon you will be full of stings. The smell of poison make them killer bees.
It depends of course what is the origing of hive. How tame the colony is.
But just warning: To catch feral hive is not beginners job. It is difficult even to experts.
If swarm is just settled down in it's hole, you can put larva frame into box and bees and queen will go around larvas.
In Finland swarm goes mostly into into ventilation canal of chimney. The measures of hole is 4 inch x 4 inch. Combs may be 3 feet long. It is really difficult to take them off.
When hive is inside tha house wall, are you just going to break down the wall. It is easy. But are you going to repair it to original condition? What is the cost? What like master of house? Is he going to break himself? When you attach on someone's house, do you know what you are doing, good work or disaster?
