Every year, these wood-destroying insects cause more than $5 billion in property damage across the country and most standard homeowners insurance policies don't cover a single dollar of it. In South Carolina, western North Carolina, and the CSRA Georgia area, the threat is particularly serious. Our warm climate, high humidity, and mild winters create conditions that allow termites to remain active virtually year-round. By the time most homeowners notice visible damage, the colony has already been at work for months and sometimes years.
At Terminix Service, Inc., we've been protecting homes in this region for over 75 years. Here's everything you need to know.
Key Takeaways
- Most homeowners insurance does not cover termite damage and thus making prevention and early detection critical
- In SC and western NC, these pests can remain active year-round due to our mild winters and high humidity
- Subterranean termites are the most common and destructive species in our region, often active for months before any signs appear
- Seeing swarmers near your home means a large, established colony is likely already very close
- Annual professional inspections are the single most effective way to catch activity before it becomes costly damage
Types & Habitats of Termites in SC & NC
Not all termites are the same and in South Carolina and western North Carolina, homeowners may encounter several distinct species, each with its own behavior, habitat, and threat level.
Eastern Subterranean Termite: The most common and destructive species in our region. They nest in moist soil beneath or near your foundation and travel through mud tubes to reach above-ground wood. Look for them along foundation walls, crawlspaces, and anywhere soil contacts wood directly.
Formosan Termite (Coptotermes formosanus): The "super termite." Formosan colonies nest underground but are uniquely capable of establishing secondary above-ground carton nests inside wall voids, attics, and crawlspaces wherever moisture is available. A mature colony can consume up to 13 ounces of wood per day. Most prevalent in SC coastal areas, Fripp Island, Isle of Palms, and Surfside, though their range is expanding inland.
Drywood Termite: No soil contact needed. They live and nest entirely inside the wood they infest such as attic joists, structural walls, door frames, and wooden furniture. Often introduced through secondhand furniture or antiques.
Dampwood Termite: Found in wood with high moisture content like decaying trees, water-damaged timber, and wood near leaky pipes or poorly ventilated crawlspaces. Addressing moisture issues is the most effective defense against this species.
Termites vs. Ants: How to Tell Them Apart
One of the most common reasons homeowners miss early activity is mistaking swarmers for flying ants. Here's how to tell the difference:
- Antennae – termites have straight, beaded antennae; ants have elbowed antennae with a distinct bend
- Waist – termites have a broad, uniform waist with no narrowing between body segments; ants have a pinched, narrow waist
- Wings – termite swarmers have two pairs of equal-length wings; flying ants have front wings noticeably larger than their back wings
- Body – termites are soft-bodied and pale; ants are harder-bodied and typically darker

Termite Swarmers: What They Mean for Your Home
Swarmers, also called alates, are the reproductive members of a mature colony. When conditions are right, they emerge in large numbers to find a mate and establish new colonies. In South Carolina and western North Carolina, swarming typically occurs in spring and early summer, most often following a stretch of warm, rainy weather, usually around dusk when the air is humid and still.
Swarmers don't travel far from their original colony. If you're seeing them near your home, a large, established colony is likely already very close and possibly in your yard, crawlspace, or inside your walls. After pairing, they shed their wings and search for a new place to establish a colony. Finding discarded wings near windowsills, doorways, or vents is one of the most reliable early warning signs of nearby activity.
Signs of a Termite Infestation
These insects are called silent destroyers for a reason. By the time visible damage appears, an infestation is often well established. Watch for these warning signs:
- Mud tubes (shelter tubes) – pencil-thin tunnels of soil and debris running along foundation walls, piers, or beams. Try breaking a small section, if live insects are present inside, call for an inspection immediately
- Hollow-sounding wood – tap on baseboards, door frames, and structural wood. A papery or hollow sound indicates feeding from the inside out
- Discarded wings – small, equal-length wings near windowsills, vents, and entry points signal recent swarmer activity
- Frass – small, pellet-like droppings near wooden surfaces are a sign of drywood termite activity
- Sounds in walls – soldier termites bang their heads against wood to signal danger; workers create faint clicking sounds while feeding. Unexplained sounds from walls at night are worth investigating
- Warped doors and windows – structural damage can cause frames to warp, making them difficult to open or close
- Sagging floors or ceilings – feeding activity can cause visible warping or sagging in flooring and ceiling materials
What Termites Actually Damage
Most homeowners think of structural wood as the primary target and it is. But termites are capable of navigating through plaster and even metal siding to reach food sources inside your home. Beyond framing and support beams, they have been known to damage:
- Drywall and drywall backing
- Carpet backing and flooring
- Furniture and built-in cabinetry
- Picture frames and antiques
- Cardboard, paper, and leather items
- Books and personal belongings
The damage isn't always replaceable. These pests have destroyed irreplaceable antiques and family heirlooms in homes across SC and NC.
What Causes Termite Infestations
Understanding what draws them in gives you a real advantage in prevention. The three most common conditions that invite activity are:
- Moisture: Leaky pipes, poor drainage, clogged gutters, and inadequate crawlspace ventilation all create the damp conditions subterranean and dampwood species need to thrive. In SC and western NC, our naturally high humidity makes moisture management especially important year-round.
- Wood-to-Soil Contact: Direct contact between wood and soil gives subterranean termites easy, hidden access to your home's structure. Foundation framing, deck posts, and porch supports that touch soil are among the highest-risk points.
- Structural Vulnerabilities: Cracks in your foundation, gaps around utility penetrations, and areas of aging or deteriorating wood all provide entry points and food sources for colonies looking to expand.
How to Prevent Termites
No prevention strategy is foolproof, but these steps significantly reduce your home's risk:
- Schedule an annual professional inspection as this is the single most effective prevention tool available
- Maintain at least 18 inches between any wood portions of your home and the soil
- Keep mulch beds at least 15 inches away from your foundation
- Store firewood at least 20 feet from your home and 5 inches off the ground
- Fix leaky pipes, improve drainage, and ensure gutters direct water away from the foundation
- Keep crawlspace vents clear and consider a vapor barrier to reduce moisture
- Inspect secondhand furniture, antiques, and wood items before bringing them indoors
- Regularly check your foundation for mud tubes especially in spring when swarming activity increases
In SC and western NC, mild winters mean these insects don't go dormant the way they do in colder climates. Year-round vigilance is essential.
When to Call a Professional
If you've spotted any of the warning signs above, mud tubes, hollow wood, discarded wings, frass, or swarmer activity, don't wait to act. The longer an active colony goes untreated, the more extensive and expensive the damage becomes.

TERMITES
WHERE TO LOOK
Termites prefer warm, moist areas (like bathrooms!), and can be found behind tile and bathtubs.
Drywood termites love a good antique—built-in cabinets, door frames, baseboards, beams, paneling, and grandma’s old dresser.
Termites often go unseen, constantly in search of food (cellulose) inside walls, ceilings and floors.
Termite FAQs
When do termites swarm in SC and NC?
Swarming typically occurs in spring and early summer, most often following warm, rainy weather around dusk when conditions are humid and still.
What is the difference between termites and flying ants?
Termites have straight antennae, a broad uniform waist, and equal-length wings. Flying ants have elbowed antennae, a pinched waist, and front wings larger than their back wings.
Does homeowners insurance cover termite damage?
Most standard homeowners insurance policies do not cover termite damage, making early detection and professional protection plans especially important for SC and NC homeowners.
How fast can termites damage a home?
Formosan termite colonies can consume up to 13 ounces of wood per day and cause severe structural damage in as little as three months. By the time most homeowners notice visible damage, the colony has typically been active for months.
What are mud tubes and what do they mean?
Mud tubes, also called shelter tubes, are pencil-thin tunnels that subterranean termites build to travel between their underground colony and above-ground food sources. Finding them on your foundation is a strong indicator of active or recent activity.
How often should I have my home inspected for termites?
Annual professional inspections are recommended for all homeowners in SC and NC, where these pests can remain active year-round. Homes in high-risk coastal SC areas where Formosan termites are prevalent may benefit from more frequent monitoring.
