I have read just how destructive the SHB are. With us purchasing our packages and nucs from the south, we have inadvertantly expanded their range, besides their normal expansion.
Just how far north have they expanded their range and when did they arrive in your area. Are they surviving the winters and becoming a pest to be dealt with. Lastly, are they surviving the winters of the more northern states. If our winters are becoming milder, then their range of survival is likely increasing as well.
I am hoping that this thread doesn't revert into frustrations against the bee production in the south as they also fill a vital need. My thoughts are that we should be prepared, if we can.
