Carpenter Ant

(Camponotus spp.)

Introduction: Carpenter ants are either completely black, or red and black depending on the species and are polymorphic, meaning individuals of the colony vary in size (1/4” to 3/4”). They are one of the largest ant species encountered and in their natural habitat, they aid in the decomposition of dead, decaying trees.

Habits: Carpenter ants excavate galleries for nests in wood and they prefer wood that is moist or unsound, such as logs, stumps, hollow trees or other soft materials (such as foamed plastic insulation board). Around or in the home, this ant species prefers areas associated with wet or damp wood such as near water leaks or behind gutters. They do not use the wood for food, but their activities can weaken a structure, although not to the extent of termites. Also, carpenter ants are active foragers, often traveling great distances in search of food. Colonies established outdoors may even send the large, dark-colored worker ants inside structures to feed on a variety of items. Homes built in wooded areas are especially subject to carpenter ant infestations.

Control: A few tips for homeowners to help prevent a carpenter ant infestation are:
• Correct any moisture problems within or around the home.
• Seal as many cracks and crevices as possible.
• Remove any dead stumps that are around the home.
• Re-locate woodpiles and wood debris away from the home.

A perimeter treatment with species specific bait is highly effective in reducing carpenter ant infestations. However, the key to the control of carpenter ants is to find and professionally treat the main colony and as many satellite colonies as possible.
