I heard lots of buzzing, saw bees streaming out of the box and thought they were getting ready to swarm. I had to suit up as they were coming at me from 40 ft. away. Upon further review, saw lots of clumps of fighting bees on ground in front of hive, more on the deck. Very noisy, very irritated. I put the reducer on, then turned it to close off the entrance to 1". two hives on either side of this one little to no affect. Log hive only 6 ft. away are hanging out bearding.
