Sawdust Piles Are Sure Sign of Carpenter Ants. The first sign of trouble was a little mound of what looked like sawdust on the raised concrete ledge in the laundry room. My neighbor has a raised ranch. In the unfinished basement area there is a narrow, half-inch gap between the wallboard and the concrete foundation.

The âsawdustâ was the byproduct of their munching.
