Eastern Subterranean Termite — the one Wilmington homes actually get

This is the termite behind essentially every residential infestation Clegg's treats in the Wilmington area. Colonies live in the soil and reach wood above ground through shelter tubes — those pencil-width mud highways you find running up a crawl space pier or a foundation wall. They need constant contact with moisture, which is exactly why coastal crawl spaces are such productive habitat.

Swarmers are the usual first sign a homeowner notices. Eastern subterranean termites swarm during the daytime, typically in spring, often on a warm day after rain — winged, dark-bodied insects with four equal-length wings that drop off and pile on windowsills. NC State Extension notes that swarming most often follows a warm rain when temperatures pass 70°F and wind is low. A swarm inside the house means a colony is already established in or against the structure.

Formosan Subterranean Termite — not established in New Hanover County

You'll see the "super termite" mentioned in coastal marketing, so it's worth being precise. Formosan subterranean termites are established in parts of the Gulf South and in South Carolina — the first U.S. record was Charleston in 1957 — but North Carolina's documented history is short and specific. NC State Extension records the state's first detection in Brunswick County in 1992, in railroad ties being used as landscaping timbers, with the infested material hauled to a landfill and no termites detected at the residence; the only other NC finds were in Rutherford County, beginning in Spindale in 1994 and again in 1996 and 2002. Extension's summary is blunt: infestations have been found in parts of Rutherford County "but not in any other areas of the state." We're not aware of any authoritative confirmation of an established Formosan population in New Hanover County or the City of Wilmington. If a company tells you your Wilmington home has Formosan termites, ask them to show you the identification.

That said, our inspectors know the differences, because port cities are how this species moves. A Formosan colony can hold well over a million individuals and forage across an area more than 300 feet wide, versus far smaller native colonies — which is where the faster-damage reputation comes from. They can also build carton nests in above-ground voids where moisture is available, rather than relying entirely on soil contact. And their swarm behavior is distinct: Formosan alates fly at dusk, from April through June, while our native swarmers fly in daylight in spring. Soldier heads are oval; native soldier heads are rectangular. If we ever saw those markers on a Wilmington job, it would go straight to NC State's Plant Disease and Insect Clinic for confirmation.

The Other Wood-Destroying Insects on a Coastal Inspection

A termite inspection in North Carolina isn't only about termites. Powderpost beetles are a genuine issue in older Wilmington homes with unfinished heart-pine floor systems and crawl space framing, and damp coastal crawl spaces suit them well. Carpenter ants nest in wood that's already been softened by moisture — a leaking gutter line or a wet band board is a standing invitation. All of these are reportable on North Carolina's official Wood-Destroying Insect Report, which is why we look for them on every inspection rather than only when someone asks.

Historic District — Pre-1900 Heart-Pine Homes

Wilmington's National Register historic district is one of the largest urban historic districts in the country, and its oldest houses were framed in dense old-growth heart pine and set over shallow, often unimproved crawl spaces. Two things follow. First, that framing is genuinely valuable and genuinely irreplaceable, so damage here isn't just a repair bill — it's a preservation problem. Second, the treatment has to respect the house: brick foundation walls, original mortar, tight crawl clearances, and sometimes historic-district review all shape where we can trench, where we drill, and where a bait station makes more sense than a soil application. Our technicians plan these jobs before they touch a shovel.

Mid-Century Neighborhoods — 1920s–1970s Crawl Space Homes

Forest Hills, laid out in the 1920s as one of Wilmington's first automobile suburbs, and the Winter Park and Sunset Park areas nearby, hold the city's deepest concentration of mature crawl space houses — bungalows, Cape Cods, and 1950s ranches under a heavy live oak canopy. The risk profile here is quiet and cumulative: original chemical soil barriers from decades ago are long gone, decades of settled landscaping have raised grade against siding, mature roots have shifted drainage, and shade keeps crawl spaces from ever drying out. These are the homes where a routine inspection most often turns up active tubes the owner never suspected.

Slab-on-Grade Construction — Newer East and North Wilmington

Slab construction removes the crawl space, which removes the easiest place to find termites early. That's the trade-off. On a slab home the colony reaches framing through expansion joints, plumbing and conduit penetrations, or the edge of the slab hidden behind brick veneer and mulch — and the first visible evidence is often inside, along a baseboard, rather than under the house. Many of these neighborhoods were built on cleared woodland where stumps and root systems remain in the soil. Pre-construction soil treatments also weaken over time, so a house that's fifteen or twenty years past its build date should not be assumed protected.

Raised & Pier Coastal Construction

Raised homes on piles and piers near the waterway are built for flood clearance, and the open underside genuinely helps — good airflow is not a termite's preferred environment. The vulnerability is different: every pile is an individual soil-to-wood pathway, and salt air, blowing sand, and wind-driven rain steadily weather the structural wood at the connections. Storage rooms, enclosed stair towers, and ground-level utility closets built in under the house re-create exactly the enclosed, humid, wood-to-ground conditions the elevation was supposed to eliminate. On these properties we inspect every pile individually and pay close attention to anything framed in below the flood line.
