If I could get them to move on somehow (smoke?), that would be great, but it's a mature nest not just the start of one. There was a guy over on DG who used to physically move nests to a less populated area -- I'm not going to attempt that! I'm not real sure what their purpose in life is, other than to sting people (are they pollinators?). The nest is above a flower bed and I have a dog & cat so poisons are not my first choice. Vinegar? (Grandma's answer for everything!)
