Carpenter ants nest in moist wood including places such as rotting trees, tree roots or tree stumps,
and logs or boards lying on or buried in the ground
They may also nest in moist or decayed wood inside of buildings.
Infestations may be caused by wood exposed to leaks, condensation, or poor air circulation
behind bathroom tiles
around tubs, sinks, showers, and dishwashers
under roofing, in attic beams and under floors
in hollow doors and wall voids
Carpenter ants may also nest in foam insulation.
A parent carpenter ant colony sometimes establishes one or more satellite nests in nearby indoor or
outdoor sites.
satellite nests are composed of workers, pupae, and mature larvae
a satellite nest does not require moisture
Satellite nests can be potentially more damaging because of the ants’ ability to nest in sound wood.
