How to Identify Carpenter Ants in Your Home
Color alone is not enough to identify carpenter ants because many ant species in New England are dark brown or black. Some carpenter ants may appear reddish-brown, but color variation exists across several species. Although carpenter ants are often larger than other ants, size alone is not always the most reliable way to identify them during an infestation.
One of the clearest ways to identify carpenter ants is by the damage they leave behind, especially tunneling through moist wood and the small piles of wood shavings, or frass, near nesting sites.
Why Pest Control for Carpenter Ants Matters
Carpenter ants can cause significant damage by tunneling through damp or weakened wood and expanding their nests over time. The longer an infestation goes untreated, the greater the risk to parts of your home’s structure. Just as important, it is difficult to feel comfortable in your home when ants are actively invading it. Early, professional pest control for carpenter ants can help stop the infestation before the damage becomes more extensive.
Common Ant Species Found in New England Homes
Although thousands of ant species exist worldwide, only a handful are commonly found in New England homes and around foundations. The most common include the following:
- Odorous House Ants: About an eighth of an inch in length, these brown or black bugs seek food in homes, particularly sweets. If crushed, they smell like old coconuts, giving them their name.
- Pavement Ants: Only about three millimeters in length, these dark brown or black ants are shiny and small. You might notice white hairs on their bodies. They nest under patios, porches, and sidewalks, coming inside to find food.
- Citronella Ants: If these ants feel threatened or get crushed, the emanating odor may remind you of lemon verbena. They are less likely to want human food than the other two species mentioned so far would.
- Carpenter Ants: This species tends to be noticeably larger than the others listed, up to half an inch in length. Usually dark brown or black in hue, they tunnel through moist wood, kicking the shavings behind them as they dig.
Our service provides effective pest control for ants in ways that are safe for you and your family, guests, and pets. If you’re already seeing signs of activity, here is how to resolve a carpenter ant infestation before the damage gets worse.

The Modern Solution to Ants
Our Carpenter Ant control program targets the specific interior and exterior areas where these pests nest, travel, and forage. Because Carpenter Ants hollow out wood to create nesting galleries, our treatment protocol is built around precision. We utilize specialized materials placed directly into both natural and excavated voids, neutralizing the colony at the source. This targeted approach establishes immediate structural protection by addressing the specific “hot spots” where activity is concentrated.

Ant Pest Control FAQs
Don’t see your question answered? Get in touch today!
What is the best time of year to start ant pest control?
If you already have ants in your home, the best time to start ant pest control is right away. For proactive prevention, spring is often the ideal time because ants become more active after winter and begin searching for food and nesting areas. Learn more about why homeowners often notice increased carpenter ants in spring and what that seasonal activity can mean for your home.
How much does an ant exterminator cost in New England?
Prices for ant exterminators from Modern Pest Services can vary based on the size of your home, the ant species involved, and the degree of the infestation, among other factors. To find out how much your customized pest control for ants would cost, please reach out for a free inspection and quote.
Why am I suddenly seeing so many carpenter ants in my home?
First, the infestation may have reached the point where you notice them and/or their behaviors. Or perhaps this is a new infestation.
In either case, if your home contains moist untreated wood, this can attract carpenter ants to exposed areas. If the wood is already softening, the impact of the ant presence can be more significant as they tunnel through the material to create their nests. So, check areas where leaks can exist in your home because moisture seeping into the wood can form a perfect place for a carpenter ant presence. Our pest control for carpenter ants helps to eliminate them.
What are the signs of a serious ant infestation?
The easiest sign to spot: ants in your home, which often occur in groups since these are social critters. As they trudge through your home in search of food, particularly your kitchen and pantry, they leave behind special chemicals that attract additional ants to the hunt.
If you notice damage to the wood in your home, carpenter ants may be causing this destruction as they tunnel through the wood. Unlike termites, they don’t eat the wood, engaging in this behavior to build nests. Outdoors, you may notice small dirt mounds created by ants, a colony that may find its way indoors to eat and drink.
Do you offer ongoing or seasonal ant prevention plans?
Our ant control program is a core component of the HomeCare Green plan, providing comprehensive protection against more than 55 common New England pests, including rodents and wasps. We prioritize proactive prevention over reactive spot treatments, utilizing environmentally friendly techniques to maintain a pest-free environment. This service includes scheduled triannual treatments to ensure consistent, year-round protection and long-term results for your home.
How can I help prevent ants from coming back?
Indoors, make sure to wipe down and sweep away crumbs, clean up spills, and otherwise make it difficult for ants to find food in your home. Store food in airtight containers (including pet food) and vacuum rugs and cushions to ensure that no crumbs hide there. Eliminate ready sources of moisture by fixing leaks. Outdoors, close up cracks and crevices that ants can use to get indoors; store woodpiles and keep mulch about six inches from your home’s foundation. Use peppermint or eucalyptus essential oils to make your home smell spicy-sweet and repel ants.
Also, rely upon our professional pest control for ants to help keep them away for good.
