Are you saying two different things here? I am pretty sure there are ways to asphyxiate bees with vaporized acids. Plus, research clearly shows that *any* disturbance to clustered bees cause activity at a time when they are supposed to be minimally active. Plus, you mention "good data" and "some research" but no specifics. Without any more details, you are handing us "alternative facts."
