Carpenter Ants in Hampton Roads

Carpenter ants do not eat wood, they hollow it out for nesting, and they almost always pick wood that moisture already softened.

Determination

Camponotus species

A large ant indoors at night, and clean sawdust below a slit opening in softened wood.

Description

These are the large black or reddish-black ants, workers up to half an inch, that homeowners spot trailing along baseboards or countertops at night. Outside they nest in stumps and landscape timbers. The trouble starts when a satellite colony moves into the structure, and the wood they choose tells the story: damp sills, leak-softened window frames, and moisture-affected joists are their preferred real estate.

Carpenter ants are one of the five wood destroying insects flagged on Virginia real estate inspection reports, so an active infestation can hold up a closing the same way termites can.

The couplet

Carpenter ant or termite: what the damage tells you

Both are wood destroying insects on a Virginia report, and both hollow structural wood, but they do it differently and they are treated differently.

What it leaves behind

Wood dry enough to stay sound is wood carpenter ants rarely choose. Their presence is a moisture alarm before it is anything else.

Field indicators

Evidence, in the order it is usually found

Homeowners meet carpenter ants at night, on a counter or a baseboard, weeks before anyone looks at the wood they came out of.

  1. 01 Large ants indoors, especially at night in kitchens and bathrooms
  2. 02 Fine, sawdust-like frass accumulating below tiny slit openings in wood
  3. 03 Faint rustling inside walls on quiet nights
  4. 04 Winged swarmers emerging indoors in spring

Grade level

Where it lives in the structure

The wood they choose tells the story. Follow the column to the band where the moisture is, because that is where the nest will be.

Exterior wall, trim, and deck

Outside they nest in stumps and landscape timbers, which is where the satellite colony comes from.

Sill, band, and floor framing

Damp sills, leak-softened window frames, and moisture-affected joists are their preferred real estate.

Consequence

What it costs to ignore

Two separate costs run at once, and the second one is the expensive one.

Structural

They work slower and their galleries are cleaner, but left alone for years they genuinely damage structural wood.

At closing

An active infestation can hold up a closing the same way termites can, because carpenter ants are one of the five wood destroying insects flagged on Virginia real estate inspection reports.

The signal

More importantly, their presence is a moisture alarm. The wood was softened before they arrived.

Correction

What we do about it

Find the nest, treat the colony, then take away the condition that made the wood attractive.

Treatment starts with finding the nest, not just the trail. We track workers back to the nesting site, treat the colony directly, and identify the moisture condition that softened the wood in the first place. Fix the leak or the damp crawl space and you remove the reason the next colony would move in.
