So, it isn't really the bugs, but the remains. I should have taken a picture before I moved the wood pile, but didn't think about it. Basically, I had a stack of firewood up close to my house. Hadn't used it since last winter and just happened to see that it looked like there was sawdust all over the wood. After closer inspection, I'm pretty sure something is eating it. Don't think it's termites, but I'm not a pro. This is what was left after I moved all the wood. It looks like a mix of sawdust, dirt, sand, and just maybe bug poop. Anyone have any ideas what this might be? What I need to do to get rid of them, although I've moved the wood far away from the house...don't really want them on my property.
