Carpenter Ant Identification Guide

What are carpenter ants?

As one of the largest species of ants living all throughout North America, carpenter ants regularly invade businesses, homes, yards, and other structures in our area of Connecticut. Carpenter ants in New Haven have segmented, oval-shaped bodies that are typically black, red, or a combination of those colors; workers grow to between 1/4 and 1/2 an inch in length and have large, powerful mandibles that they use to create nesting sites by chewing through wood.

Are carpenter ants dangerous?

Carpenter ants are not only annoying to have wandering around your property, but they are also dangerous. In addition to causing structural damage, they contaminate food sources and the surfaces of your home or business with the bacteria found on their legs and bodies. After finding their way inside while foraging for food, they may decide to stay and build satellite nests near their new food source. Attracted to water-damaged wood, carpenter ants tunnel through it to create nesting galleries where the damage they cause to a building's structural wood can be costly over time. Carpenter ants don't sting; if they feel threatened, they will deliver painful bites that are made even more painful by the formic acid they spray into the wound.

Why do I have a carpenter ant problem?

Carpenter ants are moisture-seeking pests, and having a problem with these ants could indicate a moisture problem in or around your home or business. Carpenter ants are also attracted to properties that offer them access to food. They feed on a wide variety of things including proteins, sugars, and honeydew produced by aphids and other plant-feeding insects. Compost bins, trash cans, and gardens are all potential food sources for carpenter ants and will attract them to your property. Once on your property, they will eventually find their way indoors through openings in your the exterior, usually while foraging for additional food sources.

Where will I find carpenter ants?

Carpenter ants live in parks, yards, and in or near wooded areas – creating nests in dead trees, stumps, rotting fence posts, under mulch, and in old piles of wood. If carpenter ants find their way inside, they nest behind walls, in hollow doors, inside insulation, and in structural wood found around pipes. Unlike termites, which you'll rarely see outside of the wood they are feeding on, carpenter ants can be seen wandering around basements, pantries, kitchens, walkways, gardens, and driveways while searching for food.
