Carpenter Ant

Look for relatively large ants with a single petiole node and a smoothly rounded thorax (Camponotus spp.). Workers vary in size within a nest. In Asheville, think black or dark red ants that are often active at dusk and at night. Confirm by locating wood galleries (smooth, clean tunnels) and finding frass piles — unlike termites, carpenter ants produce wood shavings, not mud tubes.

Noisy activity in walls at night, visible worker trails along baseboards or foundation, discovery of winged swarmers in late spring, small round exit holes with coarse frass below, peeling paint over infested wood, and soft or hollow-sounding structural members.

Professionals begin with a targeted inspection to map out interior and exterior satellite nests, moisture sources, and entry points. Effective treatment typically combines: placement of slow-acting ant baits to eliminate worker-forager pathways back to hidden colonies; localized void treatments (dusts or non-repellent liquid) into gallery systems; removal or treatment of heavily damaged wood; and long-term exterior perimeter treatments and exclusion work. In older or historic homes and log cabins, technicians will prioritize interior attic/cupola and sill-plate checks and treat moisture-prone areas like roof leaks, chimneys, and crawlspaces.

Reduce moisture (repair roof leaks, divert gutters, improve crawlspace ventilation), move firewood and mulch at least 20–30 feet from foundations, remove or replace water-damaged wood, trim tree limbs that contact the house, seal cracks and openings around foundations, doors, and utilities, screen vents and chimney gaps, inspect window sills and porch posts regularly, and schedule annual inspections—especially for older Craftsman bungalows and mountain cabins where native timber and historic construction provide attractive nesting sites.

Moist or decayed wood in wall voids, attics, porch posts, roof eaves, chimneys, hollow doors, log cabin timbers, and tree stumps or root systems near foundations. In Asheville, colonies often establish where exterior moisture is persistent after heavy rains or from roof/crawlspace issues.

{prevalence_note} In Asheville and the surrounding Western North Carolina Mountains, carpenter ants are a common nuisance because the region's humid subtropical climate with cool mountain influence supports both abundant moisture and extensive forested properties. Older homes, cabins, and houses with nearby wood piles or damp porches are at higher risk.
