There are times when we need to place a queen in a cage. Every extra day in a cage causes damage to the queen, hence people often ask how long can a queen bee live in a cage?
When introducing a new queen, we have to allow the workers in the new hive to become accustomed to her. If you just drop a queen in a hive she will normally be killed
Banking queens is a method where you place a whole lot of queens in cages and place these in a hive. The workers can feed the queens through the mesh, but cannot kill them.
There is always some creative clown who decides they want to smuggle bees. People get insanely fascinated with bees and the variety of different types of bees around the world.
Wild bees often choose nesting sites that are quite close to other beehives. I remember a bee removal I did when I was 19. There was a garden shed with “Some bees” in it.
