I stood back and observed the grass and did not see activity, so I worked at loosening the rest of the clump of grass. After I got it totally loose I stepped back again to make sure hanger-oners had not come home. There was one, but I saw it before it saw me. So I went and worked in another part of the garden until it had done its business and left again.
When I came back I shook the whole plant and no one appeared, so I pulled the whole clump out and just rolled it over onto its top.
I stepped back again to look for any tenants returning home and there were two. Apparently, bees cannot readjust their GPS, even when their home has moved only 12 inches.
I left the plant sitting upside down on the sidewalk for awhile and kept going back to check on them. The poor things were very confused, so I drug the whole plant out to the front of the yard and broke it apart so I could lift it into the compost bin.
By the time my daughter got home the bees had committed hara-kiri in the spider webs that cover the flower bed in front of my house. They literally had nothing to live for. But the spiders did. In fact, I think I heard one spider call his wife on the cell phone when I was loosening up the fescue right next to it: "Martha, turn on the bbq on, I've got a big one coming!"
