What causes a 'swarm' and how does it act?
I'm having my first 'experience' with a swarm of honey bees. It's not a very favorable one. They are trying to take up residnece in my fireplace chimney. They have been here for two days and I'm working on getting someone to come remove them without harm.
My question here is what actually makes them swarm? I think I know but I'm no authority. What can I expect in the way of behavior? They have been pretty docile so far. What are the chances of a repeat encounter once we have gotten rid of this bunch? Do I have something that is attracting them? Could they like the smell of the fireplace?
