I understand that bees can become irritated if gas powered equipment (i.e. lawn mowers, etc.) are operated near the colony. I believe that it is the combination of the carbon monoxide and ground vibrations that seem to contribute to the agitation.
I was planning on placing two hives in my yard where I normally operate an electric leaf blower within several feet of the possible locations from November through March. Will the bees tolerate the noise especially when they may be in winter cluster or is it best to break out the rake?
