forced air fume boards

[danno]

Next year I want to experiment on a fume board with a bellows attached on top.  Has any tried anything like this?   I would think that chemical quanity could be reduced quite a bit.  This year bee go worked really well but I have had cooler years that it didn't.

My concern with a forced air board is controlling the distribution of the fumes, too mush in the center and you will drive out the colony before you clear out the super. Dead spots or to strong an air flow will leave bees in the super and drive workers out away from the queen. IMHO  I use Bee Quick, wait my 3-5 mins. and collect the honey with no problems.  -Mike

When you put bee quick on for 5 minutes, do the bees come out the entrance looking for a fight, or do they just slide down deeper into the hive and keep quiet?

They go into the hive. If you apply to much, they will come out the front door. If that happend, remove the fume board and let it air out away from the hive. Wait a day and you can go back into the hive but using less Bee Quick.  -Mike
