Carpenter Ant Identification & Control in Hampton Roads
Complete Pest Management has been treating Carpenter Ants in Newport News and Hampton Roads since 1993. Licensed and insured in Virginia — VDACS #11694.
Carpenter ants are the largest ant species you'll encounter in Hampton Roads — and unlike odorous house ants or pavement ants, they can cause real structural damage by excavating galleries in moist, decaying wood. Finding them inside your home, especially at night, is a sign worth investigating because they almost always indicate a moisture problem in the wood they're nesting in.
Quick Facts
How to Identify Carpenter Ants
Carpenter ants are large — workers range from 1/4 to 1/2 inch, and the queen can reach 3/4 inch. Most are black, though some have reddish or bicolored (black abdomen, red thorax) coloring. The key structural identifier: a smoothly rounded thorax profile when viewed from the side (termites have a straighter thorax-abdomen connection). They produce frass — a sawdust-like mix of wood shavings and insect body parts — pushed out of their galleries as they excavate. Unlike termites, they don't eat wood; they remove it to build galleries in wood that's already softened by moisture. Finding frass is often the first sign of carpenter ant activity inside walls.
Why Carpenter Ants Are Common in Hampton Roads
Hampton Roads' high humidity, frequent rainfall, and coastal moisture creates the moist wood conditions carpenter ants prefer as nesting sites. Crawlspace homes in Newport News and Hampton with inadequate vapor barriers often develop moisture-compromised sill plates and floor joists — ideal carpenter ant habitat. Our mature tree canopy means abundant outdoor parent colonies in dead trees and stumps near homes, which establish satellite colonies inside when wood moisture conditions are right. The region's wood-frame housing stock with pier foundations gives them easy access to structural wood from below.
What to Do About Carpenter Ants
DIY Steps You Can Take Now
- ✓ Find and fix the moisture source first — carpenter ants nest almost exclusively in wood that's been softened by a water leak, condensation, or drainage problem. No moisture fix means the ants will return.
- ✓ Inspect crawlspace sill plates, around window frames, under bathroom floors, and near any roof leaks for soft, discolored wood.
- ✓ Eliminate outdoor satellite colony sources: remove dead stumps, logs, and wood debris from within 30 feet of the home.
- ✓ Trim tree branches that touch or overhang the roofline — carpenter ants use them as bridges from outdoor colonies.
- ✓ Apply residual boric acid or commercial ant bait in crawlspace areas near the foundation perimeter.
When to Call a Professional
- → You're finding large black ants inside the home at night — especially in the kitchen, bathroom, or near window frames.
- → You find carpenter ant frass (sawdust-like material) in corners, window sills, or crawlspace areas.
- → You hear faint rustling or crunching sounds inside walls at night — this is carpenter ants excavating.
- → You've identified moisture-damaged wood in the crawlspace or around windows that may already be infested.

Carpenter Ants FAQs — Hampton Roads
Key differences: carpenter ants are large, dark, and visible; termites are small, pale, and rarely seen unless you break into infested wood. Carpenter ants leave sawdust-like frass outside their galleries; termite frass is finer and mixed with soil. Carpenter ant damage shows smooth, clean gallery walls; termite damage has a muddy appearance. Winged carpenter ants have unequal wings and elbowed antennae; termite swarmers have equal wings and straight antennae.
No — carpenter ants excavate wood to build galleries but don't eat it. They're omnivores that feed on insects, honeydew from aphids, and food scraps. The damage they cause is from physically removing wood material to expand their nesting galleries, which can weaken structural members over time — particularly in wood that's already compromised by moisture.
If you're finding carpenter ants indoors in winter, the colony is likely nesting inside the structure — not just foraging in from outside. Indoor nests are kept warm by the home's heat, so ants remain active year-round. This is a more serious situation than occasional summer foragers and warrants a professional inspection to locate the nesting site.
We locate the nesting site (including any satellite nests) through inspection, apply residual treatment directly into galleries where accessible, treat the perimeter and crawlspace, and provide recommendations for the underlying moisture issue. Treatment without fixing the moisture source is temporary — the ants or a different pest will return to the same compromised wood.
