They were living in the insulation of the pipe. I picked it up in one chunk, checked I had the queen & took them to the other side of the creek. Then I used my ant vacuum to get the dozen or so angry stragglers. Put them with the rest of the colony and watched with delight as they all disappeared into a crack near the foot of an oak tree.
They will miss having "running water" but there is a stream right there... figure it out, girls! You can't live with my mom!
