An Engineer can assess the structural impact of any carpenter ant damageCarpenter ants can infest a house or building and cause structural damage. A Professional Engineer assesses the structural impact of any carpenter ant damage. If repairs are needed, the expenses are included in the expense analysis provided in the inspection report.

Carpenter ants do not eat wood. Carpenter ants excavate wood galleries to create nests. Since carpenter ants do not use wood as a food source, their damage to a building's structure is limited. Nonetheless, carpenter ants can damage a building's structure.

A qualified pest control specialist should be called in to recommend control options to control an existing carpenter ant infestation and recommend control options to help prevent future carpenter ant infestations. Check the National Pest management Association website for more information on carpenter ant inspection and treatment options.

More About Carpenter Ants

Carpenter ants live in colonies containing three castes, winged and wingless queens, winged males, and workers.Carpenter ants are among the largest ants found in buildings. Carpenter ants live in colonies containing three castes, winged and wingless queens, winged males, and workers. Worker ants have some brown coloring while queens are black. Worker ants have large heads and a small thorax. Carpenter ants have constricted waists and elbowed antennas.

Winged male and female carpenter ants (known as swarmers) emerge from mature colonies, usually from early Spring through mid-Summer. After mating, the male ants die and newly fertilized females establish a new colony in a small cavity in wood. A mature colony can take six years to develop, and may contain 4,000 carpenter ants. The larger worker ants guard the nest, battle intruders, and explore for food. Workers travel as far as 100 yards from their nest for food. Smaller worker ants expand the nest and care for the young.

Carpenter ant nests are usually established in soft, moist wood. Occasionally, nests may be established in an existing dry wood cavity. Worker ants cut galleries in the wood to expand the nest. These galleries are irregular, with smooth walls. Shredded wood fragments, which look like sawdust, are carried from the nest and deposited outside. An active carpenter ant colony produces a distinct rustling sound similar to the crinkling of cellophane.

The Difference Between
Termites and
Carpenter Ants

Flying ants and swarming termites are difficult to tell apart. Flying ants have elbowed antennae, while termites have relatively straight, bead-like antennae. Flying ants have two pairs of wings, and one pair of wings is much larger than the other pair.

Termites have two pairs of wings that are of almost equal length. The thorax of the ant is joined by a narrow waist, while the termite's thorax is broadly joined. Regardless of whether you see ants or termites, have the situation evaluated by a qualified pest control specialist.
