I am remodeling my basement in Eldersburg. The basement of our rancher has a 2 car garage on one end, then you can proceed from the garage into the living space. I was tearing insulation out of the wall between the garage and the living space and found this mound of small droppings. I reached out to my local pest service and they could not identify the droppings. They referred me to you all for possible identification. The dropping has a shiny sheen to it and sounded like beads hitting the floor as they fell out. Any identification or advice you can provide would be greatly appreciated. Thank you!
