Where to Look for Carpenter Ants in Your Home
Carpenter ants prefer to nest in moist or previously damaged wood. Common nesting sites include areas around windows, door frames, chimneys, sinks, and within wall voids. They may also establish satellite colonies in nearby trees or outdoor structures, creating multiple entry points into your home.
When to Call Professional Help
Contact professional pest control immediately if you notice sawdust-like material (frass) around wooden structures, hear rustling sounds in your walls, or spot carpenter ants consistently inside your home. These signs indicate an established colony that requires professional intervention to protect your home’s structural integrity.
