I've got a garden shed that's been FULL of carpenter bees (bumblebees) and back yard loaded with ground bees for the past 20 years. I just go about my business in the shed and mow right over swarms of the ground bees. I pretend they aren't there and they tend to ignore me. Haven't been stung a single time doing that this century. My daughter got stung once... swatting one of the carpenter bees. Luckily, they didn't go in to full attack mode. But, for typical bees, just leave them alone.. for MF'n wasps kill those bastards in sight..
