Carpenter Ants

A Carpenter ant infestation in Massachusetts may not be as destructive as a termite infestation, but it still requires prompt attention to prevent structural damage caused by their tunneling. Unlike termites, ants do not consume wood for nutrition; instead, they excavate it to create nesting spaces. The displaced wood shavings are often used to construct partitions within their tunnels.

Most ant species establish their nests in moist, decaying wood around a home's perimeter. Common nesting sites include wood retaining walls, damp porches, decks, fascia boards, dead sections of standing trees, stumps, logs and wood landscape edging. While ants can burrow into both hardwood and softwood, they generally do not cause the same level of structural damage as termites.

CARPENTER ANT PREVENTION

Effective carpenter ant control starts with structural and environmental modifications to reduce entry points and eliminate food and water sources.

✅ Begin by trimming any tree limbs that touch or overhang the roof, as carpenter ants can drop onto a structure from branches up to five feet above. Keep firewood stacks away from the house, just as you would to prevent termites.

✅ Seal cracks and gaps in the foundation, siding, windows, and doors with caulk. Additionally, install fine mesh screens over crawl space and attic vents to block potential entry points. Since ants need water to survive, eliminating moisture sources will make your home less hospitable. Repair any plumbing leaks, insulate sweating pipes, redirect air conditioner drains, and adjust sprinkler heads to prevent excess moisture near the foundation.

✅ Carpenter ants are especially attracted to damp wood. Keep all wood trim, decks, and exterior structures dry and well-maintained to deter infestations. Indoors and outdoors, maintain cleanliness by removing food sources such as sweets, grease, and crumbs that could attract ants.

✅ If you spot ant trails, use containerized baits along suspected paths and apply liquid bait into cracks and voids where ants are present. Initially, baiting may increase ant activity as workers gather the bait to bring back to the colony. Avoid killing ants during this time — the goal is for them to transport the bait to the nest for colony-wide elimination.

✅ Refrain from spraying insecticides after placing bait, as this can interfere with its effectiveness or kill worker ants before they deliver it to the colony. With patience, you should see a noticeable decline in ant activity over time.

Here is what my clients have to say about my home inspection services:

Hi Dave,

I was very impressed with you on Monday when we met in Peabody . I have never seen a home inspector spend 4 hours doing the most total inspection you did. And not only doing the inspection but educating your client at the same time.

I am sending you a new client, his name is Norman C. He is a good friend of mine. He is buying a house in Wenham on lake street and asked if I knew a "good" home inspector.

I have seen a lot of home inspectors over the years. The general contractor who couldn't make it on his own and thought that being a home inspector was another way of making money. But, all the while feeding his bad information along with his bad practices. David, your not that guy. I put you in the top 5% of all the home inspectors I've seen in the past 25 years. Well done!
