Can be exceptionally difficult to control requiring multiple treatment techniques and services.
Most common species in the Northeast is the Black Carpenter Ant (Camponotus pennsylvanicus) but they may also be red, brown or a mix of all of the colors.
Carpenter ants are polymorphic which means they can range in size depending on what their role is in the colony. Just because some might be small doesn't mean they're not carpenter ants.
Prefer moist wood (i.e. leaking windows, where porches or decks meet the house, damp basements, etc.) to set up satellite nests. These satellite nests will be used for egg storage and food storage while the main colony often still exists outside.
They eat the same types of food we do (proteins, sugars, etc) and although they don't eat wood like termites do, their damage can be just as significant.
As they carve out their "galleries" in the wood, they clean out the resulting sawdust, often times mixing it with body parts from dead ants of the colony.
Can easily overwinter inside of a home if their nest is given ample time to mature and secure a weather-proof area to protect themselves.
Carpenter ants are active year-round and can be found both indoors and outside.
