I opened up a wall where the paint was peeling and I was expecting moisture but I didn’t find any instead I did find this http://tweetphoto.com/32893341 (pic). I have no idea what it is, maybe a nest of some kind or fungus, I have no idea… any ideas?
Hopefully long dead and abandoned? It certainly LOOKS bad! Being allergic to those things I try not to get too close to them. Tread carefully until you are sure no one is home! Then find the opening they were using and caulk it up tight! Normally nothing reuses an old nest but you don’t want them to come back and start remodeling. 🙂
