Common Name: Carpenter ant
Latin Name: Camponotus spp.
Common Family Name: Ants
Latin Family Name: Formicidae

Other Names: Origin: Many species of these ants are native to North America, with several species seemingly the most likely to invade structural wood members. There are many destructive species in the Pacific Northwest states, as well as from Florida to the northeast to the southwest and in Hawaii.

Carpenter ants are large, highly poisonous ants. indigenous to many parts of the world. They prefer dead, damp wood in which to build nests. Sometimes carpenter ants will hollow out sections of trees. The most likely species to be infesting a house in the United States is the Black carpenter ant, Camponotus pennsylvanicus. Despite it’s name the Black carpenter ant may have yellow markings on it. Be wary of this variety as the sting is very painful.

Symbionts:

All ants in this genus, and also some related genera, possess an obligate bacterial endosymbiont called Blochmannia. This bacterium has a small genome, and retains genes to biosynthesize essential amino acids and other nutrients. This suggests the bacterium plays a role in ant nutrition. Many Camponotus species are also infected with Wolbachia, another endosymbiont that is widespread across insect groups.

Habitat

Resides both outdoors and indoors in moist, decaying or hollow wood. They cut “galleries” into the wood grain to provide passageways for movement from section to section of the nest. They can leave “sawdust” behind that provides clues to nesting location. If this wooden complex happens to be a wall frame within your home, structural damage may result. Moisture is the key component to look for, when managing this species.

Biology of Carpenter Ants:

The usual habitat of a colony of carpenter ants is within wood, often wood buried or partially buried in the soil. They also commonly establish “satellite colonies that may be in a structure, maintaining contact between the two colonies with the workers who travel to and from over well-defined trails. Generally there is a single queen in the colony but often supplementary queens as well. Colonies typically are around 15,000 workers when mature, but potentially could be over 100,000 workers. Foods are both carbohydrates and protein, with insects a major part of the diet. These are single-node ants without a stinger, although they are capable of biting. As they expand their colony they eject frass, which is wood chips and other debris such as leftover insect parts. This frass is often seen in structures before the ants are, as they are primarily nocturnal in habit. Carpenter ants are also typically polymorphic, with various sizes of workers in the colony.

Carpenter Ant Identification:

Worker ants are easily identified to the genus Camponotus by the single, large node and the evenly rounded profile of the top of the thorax. It has no dips or spines on it, but is an even, curved line from front to back. There is a circular fringe of hairs around the anal opening and the antennae have 12 segments. Colors range from tan to black to reddish to orange to black/red combinations. Workers vary from 6 to 13 mm in length.
