Every year, termites cause an estimated $6.8 billion in structural damage across the United States. Standard homeowner's insurance policies do not cover termite damage. That means every dollar of repair — and termite repairs can run into tens of thousands — comes directly out of your pocket unless you have active professional protection and a warranty in place before the infestation occurs.
South Carolina has three termite species capable of damaging your home. The most destructive — the Formosan subterranean termite, known in the pest control industry as the "super termite" — was first discovered on the continental United States right here in Charleston, South Carolina, in 1957. It has been spreading across the state ever since.
Our licensed termite control specialists serve Blythewood, SC and all of South Carolina with comprehensive termite inspections, treatment, CL-100 Wood Infestation Reports for real estate transactions, and termite warranty programs that cover both retreatment and structural repair.

The Eastern subterranean termite is the most widespread termite species in South Carolina and across the eastern United States. These termites live in underground colonies that can number in the hundreds of thousands, foraging constantly — 24 hours a day, seven days a week, every day of the year — through soil in search of wood to feed on. They cannot survive exposed to open air, so they build distinctive mud tubes — pencil-sized tunnels of soil and saliva — to travel between their underground colony and the wood they are consuming in your home.
Eastern subterranean termites are responsible for the majority of termite damage in South Carolina. Their constant, year-round foraging means that a colony established beneath or adjacent to your home will never take a season off. Damage accumulates silently — inside wall studs, floor joists, and structural framing — with no visible exterior sign until the damage is extensive enough to affect structural integrity or produce visible symptoms like hollow-sounding wood, sagging floors, or blistered paint.
The Formosan subterranean termite earns its "super termite" designation through sheer scale and aggression. Where an Eastern subterranean termite colony averages several hundred thousand workers, Formosan colonies average 350,000 — and can number in the millions. The average Formosan colony can consume one foot of 2×4 lumber in 25 days. That destruction rate is not a hypothetical — it is a documented consumption figure from termite research.
Formosan termites were first discovered on the continental United States in Charleston, South Carolina in 1957. They are now confirmed in Charleston, Beaufort, Dorchester, Berkeley, Orangeburg, and York counties — and the distribution is expanding. A landmark Clemson University study of 50 structures infested with Formosan subterranean termites in Charleston found that 94% were infested from ground-based colonies — meaning soil treatment programs are effective against the vast majority of Formosan infestations. The remaining 6% involved aerial colonies established above-ground when moisture conditions allowed — a scenario that soil treatments alone cannot address.
Formosan termites can also infest live trees. Charleston researchers documented Formosan infestations in 17 different tree species. Live trees near your home's foundation serve as a potential Formosan reservoir — another reason why annual inspections are essential in coastal South Carolina.
Drywood termites are less common in South Carolina than subterranean species but present a distinct threat because they do not require soil contact. They live entirely within wood — in attic framing, structural walls, furniture, and wooden decorative items — without any connection to the ground. This makes them impossible to detect with soil-focused treatment programs alone, and harder to identify because they produce no mud tubes.
Drywood termites are particularly common in coastal homes where wood remains warm year-round, and in older homes with substantial exposed wooden elements. A critical and underappreciated transmission route: drywood termites can infest and travel with used furniture, picture frames, and wooden antiques. Inspect any secondhand wooden items carefully before bringing them into your home.
The single most reliable indicator of subterranean termite activity is the presence of mud tubes — pencil-sized tunnels of soil and termite saliva running along foundation walls, crawl space piers, and exposed framing. Mud tubes allow termites to travel from underground to wood above without exposure to open air. Their presence confirms active termite foraging activity at your structure. Even old, inactive tubes should be assessed — they indicate past activity and may indicate conditions favorable to reinfestation.
Subterranean termites consume wood from the inside out — eating the soft interior grain while leaving a thin shell of surface wood intact. Tapping suspect wood with a screwdriver produces a hollow sound rather than a solid thud. In severe infestations, a screwdriver pressed firmly against affected wood will puncture the surface easily — revealing hollow galleries within. Floor joists, window frames, door frames, baseboards, and structural wall studs are the most commonly affected locations.
Termite swarmers — the reproductive members of a mature colony — emerge in large numbers, typically on warm days after rain between April and July in South Carolina (Formosans swarm April-July; Eastern subterranean species typically swarm in spring). Swarmers are attracted to light and are frequently found near windows, windowsills, light fixtures, and sliding door tracks. Finding discarded wings — swarmers shed their wings shortly after landing — near these locations is a strong indicator of a mature termite colony nearby. Many homeowners mistake termite swarmers for flying ants. The distinction: termite swarmers have straight antennae and a uniform body width (no waist), while flying ants have elbowed antennae and a pinched waist.
Subterranean termites work within wood immediately beneath painted surfaces. Their activity creates moisture and heat that cause paint to blister, bubble, or separate from the surface in a pattern that mimics water damage — but with no moisture source present. If your paint is blistering on walls or baseboards where no plumbing or roof penetration could explain it, termites should be investigated.
Drywood termites produce distinctive fecal pellets — called frass — that they push out of kick-out holes in infested wood. Frass accumulates as small piles of granular material near baseboards, below wooden window frames, or on surfaces beneath infested wood. Frass is pale to dark brown and roughly the size and shape of fine sawdust or coffee grounds with a ridged appearance when examined closely.
Liquid soil treatment — using professional termiticides such as Termidor (fipronil) — creates a continuous chemical barrier in the soil around and beneath your structure that termites cannot detect, avoid, or survive crossing. Unlike older repellent termiticides that termites detected and tunneled around, modern non-repellent formulations like Termidor are transferred between termites through contact, spreading through the colony. Liquid treatment is applied by drilling and injecting through slabs, treating the soil in foundation trenches, and treating void spaces — creating a complete barrier around the structure's perimeter and beneath vulnerable areas. Liquid treatment provides immediate active colony elimination and lasting residual protection. It is particularly effective for Eastern subterranean termite infestations and for the 94% of Formosan infestations that originate from ground-based colonies.
Termite bait systems — the most recognized of which is the Sentricon system — involve installing bait stations in the soil around your home's perimeter. Foraging termites find the bait, feed on it, and carry it back to the colony — including to the queen. The active ingredient in Sentricon disrupts termite molting, gradually eliminating the entire colony from the inside out. Bait systems are a lower-chemical-impact alternative to liquid treatment and are particularly effective as ongoing preventive protection — the EPA awarded Sentricon the Presidential Green Chemistry Challenge Award, recognizing it as an environmentally responsible treatment approach. Bait systems require time to produce full colony elimination — typically weeks to months — and are most effective when maintained as an ongoing monitoring and replenishment program rather than a one-time installation.
For maximum protection — particularly in high-pressure situations, Formosan-active areas, or properties with prior termite history — a combination of liquid soil treatment and ongoing bait station monitoring delivers both immediate active colony elimination and long-term residual protection. This approach is the standard recommendation for most South Carolina properties in higher-risk zones.
Borate pretreatment — the application of borate-based compounds directly to wood framing during construction, before walls are closed — provides protection that is built directly into the structure. Borate penetrates deep into wood, making it permanently unpalatable to termites and resistant to wood-decay fungi. This treatment is applied after framing is complete and before insulation and drywall are installed. Borate pretreatment is the most effective form of termite prevention available for new construction — protection that lasts for the life of the building.
The CL-100 is South Carolina's Official Wood Infestation Report — the document formally required at most real estate transactions in the state. It is prepared by a licensed pest control professional following a visual inspection of the property and documents the presence or absence of wood-destroying organisms including subterranean termites, drywood termites, other wood-destroying insects, and wood-decay fungi. It also includes moisture readings, as elevated wood moisture — at or above 20% — is a significant termite risk factor and trigger for wood-decay fungus activity.
Despite being commonly called a "termite letter" or "clearance letter," the CL-100 is neither. It is explicitly a snapshot of the property's condition on the date of inspection — not a guarantee or warranty against future infestation. The report itself states this prominently. A clear CL-100 means no evidence of active infestation was found in accessible areas on the day of inspection. It does not mean your home will not develop an infestation after closing.
Virtually every mortgage lender in South Carolina requires a CL-100 before approving a loan — because the entire state falls in the nation's highest termite risk zone, and lenders protect their collateral accordingly. FHA and VA loans typically require the NPMA-33 form, which covers wood-destroying insects specifically. Most conventional lenders accept the CL-100, which is more comprehensive. The standard South Carolina real estate contract (SCR310) includes a dedicated section for the CL-100. The report is valid for only 30 days in South Carolina — because termites can establish and spread rapidly, lenders require a recent snapshot of the property's condition.
Our licensed inspectors examine all accessible areas of the property — crawl spaces, attics, exposed framing, foundation walls, and perimeter exterior. We look for live termites, mud tubes, damaged wood, evidence of prior treatments, wood-decay fungi, and moisture conditions conducive to infestation. We note all inaccessible areas that could not be inspected. We take photographs of all findings and provide a detailed digital report typically ready the same day or within 24 hours.
This is the most important thing to understand after closing: a clear CL-100 does not protect you against future termite activity. Your homeowner's insurance almost certainly does not cover termite damage. A termite bond — a service agreement with a licensed pest control company that includes annual inspections, retreatment if termites appear, and in comprehensive programs, structural repair coverage — fills this gap. We offer termite bond programs starting immediately after closing for any property we inspect.
A Retreat-Only warranty — sometimes called a Retreatment Bond — covers the cost of professional retreatment if termites appear between annual inspection visits. It does not cover the cost of structural damage repair. This is the lower-cost warranty option and is appropriate for properties with lower structural damage risk or where damage repair coverage is less of a financial concern. Annual renewal inspections maintain the warranty.
A Retreat & Repair warranty covers both retreatment and structural repair costs if termites cause damage during the warranty period — up to a specified maximum, commonly $250,000. This is the comprehensive option — the one that functions most similarly to an insurance policy against termite damage, and the one most appropriate for South Carolina's high-risk termite environment where Formosan infestations can cause significant damage in a short period. Annual renewal maintains coverage.
Our termite warranty programs are fully transferable to new owners at no additional cost when a home is sold. A transferable termite warranty is a genuine selling advantage in South Carolina's real estate market — it provides the buyer with documented protection history and ongoing coverage, which many buyers and their lenders specifically look for.
Not all termite warranties cover Formosan termites in addition to Eastern subterranean termites. In coastal South Carolina where Formosan pressure is documented, this matters. Our warranty programs specifically cover both Eastern subterranean and Formosan subterranean termites — confirming coverage before treatment begins rather than discovering an exclusion at claim time.
We conduct a thorough inspection of your property — interior and exterior, from crawl space to attic — identifying all evidence of active infestation, prior damage, mud tubes, moisture conditions, and conducive conditions that increase infestation risk. We provide a detailed written report with photographs.
Based on the inspection findings, property construction type, and termite species present or at risk, we develop a treatment plan selecting the appropriate product and delivery method — liquid soil treatment, bait system, or combination program. We explain the options, their timeline, and their warranty implications before any work begins.
We apply the selected treatment program — including all required drilling, soil injection, bait station installation, and void treatments — in full compliance with South Carolina pesticide application law and product label requirements. Our technicians are licensed applicators with specific training in termite control.
We conduct annual inspection visits to monitor treatment effectiveness, assess for new activity, replenish bait stations as needed, and maintain your warranty documentation current. Annual inspections are required to maintain warranty coverage and produce the ongoing documentation record that supports future real estate transactions.
Termites are strongly attracted to moisture. Ensure gutters and downspouts direct water away from the foundation. Grade soil so that it slopes away from the structure. Fix any plumbing leaks promptly — including crawl space condensation lines. Keep crawl spaces dry with adequate ventilation and vapor barrier. Elevated wood moisture readings — above 20% — dramatically increase termite risk and are flagged on every CL-100 inspection.
Direct contact between wooden structural elements and soil is the primary termite entry point. Maintain a clear gap between soil and any wooden structure element. Remove wood debris, stumps, and dead tree material from your property perimeter. Store firewood elevated and away from the structure.
Shrubs, vines, and ground cover growing against the exterior of your home conceal mud tubes from visual inspection and create moisture conditions that attract termites. Maintain a clear zone of at least 12 inches between any vegetation and your structure's exterior.
In South Carolina's Termite Infestation Probability Zone 1 environment, an annual professional termite inspection is the minimum reasonable precaution for any homeowner — with or without active treatment in place. Early detection catches infestations before damage becomes structurally significant, dramatically reducing the cost of intervention.
Termite treatment pricing depends on the size of the structure, the construction type (crawl space, slab, basement), the treatment method selected, whether active infestation is present, and the warranty program selected.
Crawl space, slab, or basement — each needs a tailored treatment plan and price.
Retreat-only vs. Retreat & Repair up to $250K changes long-term value.
A preventive bait station installation on a standard crawl space home differs significantly in cost from a liquid soil treatment for an active Formosan infestation on a large slab-on-grade commercial building. Annual warranty renewal costs are far lower than initial treatment costs. The cost of treatment — even comprehensive treatment — is a fraction of the average termite damage repair cost, which commonly runs $3,000 to $8,000 for moderate infestations and far higher for severe structural damage.
No. Standard homeowner's insurance policies in South Carolina and throughout the United States classify termite damage as a preventable maintenance issue and exclude it from coverage. This makes a Retreat & Repair termite warranty the only financial protection available against termite damage repair costs. We discuss warranty options as part of every termite inspection.
Our warranty programs specifically cover both species — not just the more common Eastern subterranean termite. In Blythewood and across coastal South Carolina, Formosan coverage is essential.
We issue South Carolina CL-100 Wood Infestation Reports with same-day or next-day turnaround — meeting the tight deadlines of real estate transactions. We coordinate directly with your realtor and closing attorney.
