Carpenter Ants — Control Tips

  • The key to control is finding the nest or nests. Look for piles of sawdust or carpenter ant trails at night when they are most active.
  • Carpenter ants prefer damp wood over dry wood. Increase ventilation in areas like attics, basements, and crawl spaces to reduce moisture.
  • Repair all leaks in the roof, attic, inside the home, and the foundation.
  • Seal areas where plumbing, cable, or electrical hardware enters the home.
  • Consider increasing ventilation or insulating pipes if condensation is a constant source of moisture near wood.
  • Replace water damaged wood, and store firewood several feet away from structures.
  • Keep tree limbs trimmed away from wood structures so that the ants cannot use the limb as a bridge to the structure.
