North Carolina's Piedmont is firmly inside termite territory. In Winston-Salem, the eastern subterranean termite is the species responsible for nearly all structural damage, and its colonies live in the red clay beneath neighborhoods old and new. Warm rain in April and May often triggers swarms, and the sight of winged insects around a window or porch light is the cue many homeowners get.
How this termite works
Eastern subterranean termites nest in soil, where they stay damp, then forage for wood through narrow mud tubes that protect them from dry air. They enter through cracks in foundation walls, expansion joints, gaps around plumbing and wood that touches the ground. They consume the soft, springwood layers of lumber first, leaving thin outer layers behind, so damaged wood can look intact while being hollow. Drywood termites are not a normal Piedmont problem, and Formosan termites are not established in the Winston-Salem area.
Parts of town and house types at risk
- Historic wood-frame homes in the West End, Washington Park and around Old Salem, where original sills and porch framing may be close to soil.
- Mid-century ranches in Buena Vista, Ardmore and the surrounding area, often built over crawl spaces with moisture issues.
- Newer subdivisions built on graded clay, where debris buried during construction can feed colonies.
- Homes with finished basements that cover the foundation wall and hide mud tubes.
What to watch for
- Swarms of winged insects in spring, particularly after rain.
- Mud tubes on piers, sill plates and the inside of foundation walls in the crawl space.
- Wood that sounds hollow when tapped or gives way when probed.
- Discarded wings near windows and doors.
- Sagging floors or soft spots near bathrooms and kitchens.
Inspection and treatment
An inspector crawls under the house when possible, checks the sill plates, probes joists and inspects the exterior for tubes and soil contact. If activity is found, treatment often involves a liquid termiticide in a trench and drilled holes along the foundation, a bait station system, or a combination. Crawl-space moisture is usually addressed in the same plan with drainage, vapor barriers, or ventilation improvements, because dry wood is far less attractive. Ask for a written report that shows where activity was found.
Cutting the risk
- Fix leaking pipes and condensate lines under the house.
- Grade soil so water runs away from the foundation.
- Keep wood-to-soil contact to a minimum, including trellises, steps and siding.
- Store firewood away from the house and off the ground.
- Remove old stumps and buried scrap lumber from the yard.

Buying or selling a house here
In Forsyth County, lenders commonly ask for a wood-destroying insect inspection on a sale. If past treatment appears in the records, ask about the method used and whether any warranty transfers, since terms vary by company.
Why Winston-Salem soil matters
The red clay under Winston-Salem drains slowly, so water lingers beside foundations after storms. That lingering moisture is attractive to subterranean colonies, which is why drainage fixes are a routine part of termite plans in Winston-Salem and across Forsyth County.
Termite FAQ
Do termites go dormant in a North Carolina winter?
Activity slows in the soil, but colonies in heated structures or deep in warm crawl spaces can feed through winter.
Is a new house safe?
Not automatically. Buried wood scraps and soil grading problems can attract termites to new builds.
What is the difference between ants and termites with wings?
Termites have a broad waist and straight antennae. Ants have a narrow waist and bent antennae.
How long does treatment take?
Many treatments are completed in a day or two, with follow-ups to monitor.
