The article in March American Bee Journal relating to "Bee Busting",(page 166 )
The author indicated he uses nitrogen fertilizer in his smoker. It is
purported that during the burning process the fertilizer converts to nitrous
oxide and causes bees to evacuate the colony UNHARMED, (but happy). Anyone
having information which substaniates this or any other material which will
cause the bees to evacuate the void UNHARMED, please contact me. Thanks.
