Bees don't drop bombs
That is a political statement and this is a Forum about bees, sooo...
I suppose that you are a pacifist
Anyhow from one who was a potential bomb dropper, for a long time, your question is old hat. There was, and probably still is a method of beekeeping that did just that; Start fresh in the spring with a package of bees and a queen, let them do their thing, produce, hopefully, a good crop of honey and at season end gas the bees in the hive and be done with the problem of overwintering. Start fresh next spring. Go huntin' and fishing instead of worrying about some insects
Canadian beeks did just that. Some of them at least. Now since there is a restriction on obtaining packages of bees from the US, where their bees came from, I believe that some of their bee killing practices have changed. Perhaps some Canadian beeks will chime in and fill us in with the gory details.
Actually if one were to consider all factors involved the bee killin' after one season does have it's merits, as was explained to me by a Canadian beek. One important factor being that commercial beeks could get by with using low skilled labor, read cheap, labor. Also read here " Hispanic or illegal laborers here in the US ".
Overwintering bees in Northern climes is fraught with potential problems and is expensive. Just think, there is a nectar season of, at most, four months in Canada and eight months of worry over keeping the bees alive. Read some of Finsky's post to get an idea of what all is involved keeping bees in cold climes since he has been doing this for a loooong time.
Hope I haven't dropped a " bomb " on your little world of concern.
