I have a few supers to remove today or tomorrow so I'll try spraying them
down with water and mint oil laced water instead of using the smoker to
see if there's any difference in aggressiveness.  I may try using sugar
water
and sugar water with mint oil also.  One possible complication is that
my bees now associate the smell of mint oil with FOOD.  Wonder how that
happened... ;)
 
Didn't someone post successful results a few
months ago, spraying a water-smoke flavoring mixture?
