I'm happy to pick up swarms, but I draw the line at small children and neighbour's dogs. :D
LJ does have a point about the odd beekeeper that doesn't try to manage swarming. They should at least be ready to catch them.
It's irresponsible not to.
Had one of Simon's for 3 years now. First year there was a fault with the hood, it became rusty after washing. He replaced it straight away. Still going strong.
I believe that Derek was talking about maximum efficiency.
Of course they'll fill them with honey, they would fill an empty space with it if they had nothing else.
