  • Very little information is known on the Pavement ant colony. Most colonies are located under sidewalks, building slabs, large rocks. It is common to see sand piles and small soil particles in structures near cracks in concrete slabs, foundations or cracks in sidewalks.

Carpenter ants have several species (Camponotus species) The 2 most destructive species in the Western United States are the C. modoc and the C. Vicinus. Carpenter ants are among the largest ants in north America with workers ranging from 1/8"- 34" long. The modoc Carpenter Ant is black in color while the Vicinus Carpenter Ant varies in color but is usually red and black.
  • Mature colonies may range from several thousand to 15,000 including satellite nest. Carpenter Ants complete their life cycle in about 60 days. Swarmers do not appear in the colony until usually 3-4 years.
  • Carpenter Ants do not consume wood but excavate it to make their nest. This often begins in an area where there is damage from water or wood decay. From here they will expand the nest into sound wood and compromise structural integrity. They will nest in wall voids, hollow doors foam insulation, & fiberglass insulation.
  • Carpenter Ants feed on sugar solutions from honey dew producing insects such as aphids, sweets and the juices from insects they capture.
