couple of things occurred to me
-the statement you are doing something wrong doesn't sound like I intended, something is going wrong is better
-maybe the most important and obvious thing I missed is the sound, pay close attention to the sound.
-stop if they sting, smoke a little step away and let them calm, you can't go thru with them stinging you.
-Can't kill any. The odor released can set them off. No reason to squash any if you plan your moves in advance and proceed slow and steady, they will accommodate your action.
-Keep a calm assertive state of mind. Increased heart rate, anxiety, fear, will have you releasing scents that could result in defensive reactions.
