Carpenter Ant Sawdust Piles (Frass) — Chicago, Illinois
Small piles of fine, sawdust-like material (frass) appearing near baseboards, windowsills, or door frames are a telltale sign that carpenter ants are excavating galleries inside your woodwork. Unlike termites, carpenter ants do not eat wood—they hollow it out to nest, weakening structural members over time. A pest-control technician can locate the parent colony and satellite nests, apply targeted gel bait or dust treatments into wall voids, and recommend moisture corrections that remove the conditions carpenter ants seek.
