The average Carpenter Ant colony contains more than three thousand worker ants and one queen. In some situations, colonies may also form satellite nests that contain larvae, pupae, and worker ants. When combined with the main colony, the population way extend upwards to fifteen thousand.
Carpenter Ant nests typically form in decayed wood and voids. Over time, they may expand into sound wood as well. If you suspect a Carpenter Ant infestation, keep an eye out for coarse piles of sawdust mixed with insect body parts. Also listen for the sound of worker ants chewing through wood. Outdoor nests are typically located in dead/damaged trees or rotting stumps and logs.
Carpenter Ant foraging trails will extend out three hundred or more feet from the nest. Trails between parent and satellite nests – known as “Trunk Trails” – are clear of debris and vegetation, and they tend to travel over lawns. Carpenter Ants will enter homes and other structures through window frames, doors, eaves, plumbing/utility lines, and by branches that touch the structure.
The peak foraging time for Carpenter Ants is at night.
