Since I moved production outside, the last 5 batches I guess, these guys keep finding me and swarming when I try to brew. Mass bee/wasp suicide as they jump into the boiling wort. A mesh cover to keep them out, that was suggested, and maybe a bee suit for me? Imagine what the neighbors would think, good thing I don't have neighbors. Outside in my bee suit trying to brew a batch. That would get attention.
