Carpenter Ants: What That "Sawdust" By Your Baseboards Might Mean
Carpenter ants are one of the more misunderstood pests we deal with in the Inland Northwest. Unlike termites, they don't eat wood, but they do tunnel through it to build their nests, and they prefer wood that's already softened by moisture, like around a leaking window, a deck post, or an older roofline.
A few signs to watch for: small piles of frass (a sawdust-like material) near baseboards or window frames, faint rustling sounds inside walls, and worker ants noticeably larger than typical household ants.
If you're seeing any of these signs, message us for a free inspection and we'll help you figure out whether it's an active nest or just foraging activity.
