Signs of Carpenter Ants in the House

As they burrow into wooden beams in houses, carpenter ants are highly destructive. Tiny as they are, the pests easily enter homes through:

  • Cracks in windows and doors.
  • Holes in siding and roofs.
  • Fissures in building foundations.

Carpenter ants set up parent nests in addition to several satellite colonies in close proximity to each other, so individuals may encounter multiple nests in infested homes.

Damp Environments
Colonies are typically found in moist or decaying wood where there’s plenty of condensation and poor airflow, including:

  • Under bathroom tiles
  • Around dishwashers
  • Under roofing
  • Around windows
  • Under tubs, sinks, and showers

Dry Areas
However, dry areas like those found in insulation, wall voids, and hollow doors become infested with workers, pupae, and larvae.

Control & Prevention

Prevention is key to reducing the possibility of encountering carpenter ant infestations in the house, and the best form of prevention is habitat modification.

Habitat Modification
To make homes less favorable to the pests, homeowners should:

  • Repair weathered or rotted wood.
  • Make sure attics and crawl spaces are well ventilated.
  • Clean out gutters.
  • Keep soil away from wood.
  • Eliminate collections of moisture.

Firewood stored near building foundations, tree stumps, and debris around yards attract the pests, so individuals should do their best to eliminate them.

Cracks & Gaps
Finally, thoroughly check for cracks around windows and doors and seal any openings.


Over-the-counter removal techniques can be sporadically successful but are often ineffective in the long-term without the expertise of professional pest control.
