I tried almond extract. Mixed 1:2 with water. No effect. Do not use an escape board with bee quick. They cannot get out of super fast enough with escape board installed. To use bee quick, put a piece of towel cut to the size of the board in the inner board and staple it in place. Spray a light coat of bee quick all over the board and place it on top of the super for five minutes. Then remove it and place it on top of a fume board. Partially cover it with card board to let the remaining bees to escape.
