Carpenter Ant (Winged Reproductive/Swarmer)

Natural Habitat

Nests are located in moist or decaying wood in forests, but can also be found in residential wooden structures such as wall voids, porch pillars, and windowsills.

Diet & Feeding

Omnivorous; they feed on honeydew from aphids, plant juices, and other insects. Inside homes, they seek sweets, fats, and meats.

Behavior Patterns

Winged reproductives (alates) emerge in spring/early summer for nuptial flights to start new colonies. Unlike termites, they do not eat wood but excavate it to create galleries for nesting.

Risks & Benefits

Potential risk for structural damage to homes if colonies are established in building timbers. Benefits ecosystems by recycling dead wood into the soil and serving as a food source for birds and mammals.
