Just wanted to thank you for your post. As a first year beek I've just installed my first three packages of hives and have so far done 3-4 additional inspections. Besides finding out that bees hate bee brushes (my first and only sting) I've been amazed at how docile they've been, even with no smoking. I've always worn my gear, and even had several bees within the veil, but the above is a good reminder to not get complacent. I had a quick robbing incident the other day from open feeding and was amazed at the difference in the attitude of the hives versus 1 hour earlier. You can't blame bees being bees, and the responsibility rests with the beek to keep protected and to manage the hives in such a way that pets or neighbors don't pay the consequences.
