Carpenter Ant Problems in Portsmouth, NH
Portsmouth's historic downtown is some of the most at-risk real estate in New Hampshire for carpenter ants. Homes built in the 1800s and early 1900s — common throughout the South End and Islington Street corridor — have old-growth wood framing that carpenter ants find ideal for nesting. Add coastal humidity from the Piscataqua River and tidal exposure, and you have the perfect moisture conditions that attract and sustain colonies. Tom Pray has been eliminating carpenter ant colonies in Portsmouth homes for over 35 years. He knows which neighborhoods see early spring activity, which foundation types are most vulnerable, and how to eliminate colonies on the exterior without disrupting your home.
