While getting ready to put the workbench I'm going to use for the welder in, I had to take off a place where I'd tacked up a piece of plywood below where we used to have an indoor basketball hoop and I didn't want anyone running into one of the nails. What I found when I took the plywood off, scares me. What I saw was ants, but I didn't know ants could do this, unless termites lived their previously and then the ants moved in, I don't see how this happened. I took some pictures, and then doused the area with bug spray. They sure did have a little channel in there. It's weird though, because no where else do I see anything like this, I'm lucky enough to have just the studs so I can see everything out front without tearing any drywall out. So have any of you seen anything like this?
