Carpenter ants are the most destructive ant species in New Jersey. Unlike termites, they don't eat wood — they excavate it to build nests, leaving behind smooth tunnels and piles of sawdust-like frass. In Roselle Park, carpenter ants thrive in homes with moisture issues: leaky roofs, damp crawl spaces, window frames with condensation. Left untreated, a carpenter ant colony can cause serious structural damage. Sousa Exterminating Co. specializes in locating and eliminating carpenter ant colonies inside walls and structural wood.
Call 908-352-7959 — Free QuoteCarpenter ants create galleries inside wood — long, smooth tunnels where they raise their young. They prefer softened or moisture-damaged wood but will excavate sound wood once a colony is established. A mature colony can contain 10,000+ ants with satellite colonies throughout your home. Common nesting sites include wall voids near bathrooms, roof rafters, window frames, porch columns, and deck supports.
We do not just spray baseboards. Our carpenter ant treatment begins with a full property inspection to locate the main colony and satellite nests. We use moisture meters and acoustic detection to find nests inside walls. Treatment includes direct wall-void injection, targeted baiting systems, perimeter barrier treatment, and moisture recommendations to prevent re-infestation.
Large black ants (3/8 to 1/2 inch) inside your home, especially in spring or at night. Piles of fine, sawdust-like frass near baseboards, window sills, or under sinks. Faint rustling sounds inside walls. Winged ants emerging indoors (swarming indicates a mature colony nearby). Wood that sounds hollow when tapped.
Carpenter ant treatments start at $350, including wall-void injection and perimeter treatment. Severe multi-colony infestations may require 2-3 treatments. All work includes a satisfaction guarantee.
