Seeing large black ants in your home? Carpenter ants are one of the most common structural pests in New England. Unlike termites, they don’t eat wood — but they tunnel through it to build nests, which can weaken structural materials over time.

Our technicians locate nesting areas, treat active colonies, and help prevent carpenter ants from returning.

Signs You May Have Carpenter Ants
Carpenter ants are often active at night and can go unnoticed until the infestation grows. Common warning signs include:
• Large black ants inside your home • Sawdust-like material (frass) near baseboards or windows • Rustling sounds inside walls • Winged ants appearing indoors in spring • Ant trails along walls, foundations, or decks
If you notice these signs, it’s important to address the problem quickly before colonies expand.

Why Carpenter Ants Are a Serious Problem
Carpenter ants can cause structural damage if left untreated. Over time, colonies can expand through wall voids, beams, and other wooden structures.
Potential risks include:
• Structural wood damage • Multiple satellite colonies forming in the home • Hidden nesting in walls or insulation • Recurring infestations if not treated properly
Professional treatment helps ensure the entire colony is addressed.
