Termite control here means finding out which termite is present, where it is feeding, and how it reaches the wood, then treating that route. A technician inspects the crawl space or slab edge, separates Formosan from native subterranean termites, and explains the options before any work starts.
Termites are the baseline pest in North Charleston, not a seasonal extra. Formosan subterranean termites were introduced to Charleston in the mid-1950s, and Clemson entomologists now count them as established across much of Charleston County. Native subterranean termites live in the same soil and often in the same houses. The two do not behave the same way, so a visit that treats one as if it were the other can leave a working colony in place and a homeowner with a false sense of safety.
Most of the older housing in the city sits on vented crawl spaces, with joists, sub-floor framing and cooled ducts close to the ground in very high humidity. That damp is what brings subterranean termites to the framing, because they need moisture as much as they need wood. A visit usually begins under the house, where the wood is most exposed, and then works outward to the perimeter, the porch piers and every point where soil touches wood. The technician notes what is visible, what is damaged and which parts of the structure are involved, and explains that before recommending anything.
If you are seeing mud tubes, hollow-sounding wood or a swarm in the house, call (855) 974-4733. Phones are answered 24/7, and a visit the same day is possible when a technician is free. The price is explained and approved before work starts, so you know what you are agreeing to before any treatment begins.
Look for mud tubes, soft or hollow wood, and small piles of pale frass near the framing. A technician can confirm what you are seeing by going under the house with a light.
The clearest sign is a mud tube, a thin earthen channel that subterranean termites build to travel between the soil and the wood. They often run up piers, concrete block or the sill plate, and they can be easy to miss behind a stack of stored boxes or a lattice skirt. Wood that sounds hollow when tapped with a screwdriver handle is another warning, and so is a joist or sill that gives under light pressure.
Most of the older housing sits on vented crawl spaces where the framing is exposed and damp. The inspection begins there because that is where the evidence is.
A great many houses in the city sit over vented crawl spaces. Air moves through the vents, and in very high coastal humidity the air entering the space carries a lot of moisture. Surfaces inside an air-conditioned house, such as ducts and joists, can sit below the dew point of that outside air, so the moisture condenses and stays. Damp sub-floor wood is what subterranean termites need, and a crawl space that stays wet gives them a steady reason to come up into the framing.
The main factors are how much of the structure is involved, how hard it is to reach the sub-floor and perimeter, and the age and construction of the building. The price is explained and approved before work starts.
The size and footprint of the house matter, and so does the number of structures on the lot, since a detached garage or a porch enclosure is inspected as part of the same job. Construction type changes the work as well. A pier-and-crawl-space house takes different access and different methods than a slab home, and an older building with a shared chimney or a raised porch takes more time to inspect properly.
Follow-up visits check whether the activity has stopped and whether anything new has appeared. The schedule is agreed with you when the plan is written.
A treatment is not a single moment in time. Termite colonies can be large, and some of the work takes effect over weeks rather than hours. A follow-up visit lets the technician see whether mud tubes are still being built, whether new swarms have appeared and whether the moisture conditions under the house have changed.
A South Carolina Wood Infestation Report, the CL-100, is what sales and closings usually run on here. Lenders and closing attorneys set the timing, so ask yours.
The CL-100 is the state's official report of visible infestation and damage caused by insects and decay. Sales and closings in this area usually depend on it, and many buyers ask for it as a matter of course. An inspection for a sale covers the area that the regulation sets out, and the report records what is visible in that area. The CL-100 page explains what the report does and does not cover.
A treatment carried out for a termite problem does not automatically satisfy a sale, and a report does not replace a treatment. The two answer different questions. If you are selling and you already know termites are present, tell the technician before the inspection so the report and the treatment history can be explained clearly.
Do not dig around the foundation, cut into wood to find the source, or spray soil yourself in an attempt to reach the colony. Those steps can spread the colony, disturb the mud tubes that show where it is feeding, and expose you to products that need to be applied according to their labels. Do not crawl through a damp space with exposed wiring or unstable piers without a light and a plan for getting out. Keep wood piles, mulch and stored cardboard away from the foundation while you wait for a visit. If a sign is spreading quickly or a floor feels unsafe to walk on, keep weight off that area and call (855) 974-4733.
The first call is about the signs themselves: where they showed up, when, and whether anything swarmed. A swarm seen indoors in the afternoon points one way, and a swarm at dusk points another, so the time of day is worth remembering. Nothing is treated on the phone.
The technician works through the crawl space with a light, checking the sub-floor framing, the sill plates, the piers and the duct runs. Damp boards, soft wood and any mud tubes are recorded wherever they are found. This is the stage where most of the real information comes from.
Outside, the work looks at every place where soil, mulch or a stacked wood pile touches the structure, along with porch steps, exterior trim and the edges of any slab additions. Gaps where a utility line enters the house are noted as well, because they give termites an easy route into the framing.
Formosan and native subterranean termites are handled differently, and so is drywood work, which does not need soil contact at all. The technician works out which one is present and how it is reaching the wood, since the route decides the method. You will hear the reasoning, not just a recommendation.
The findings and the proposed treatment are explained in plain terms before anything starts. The price is explained and approved by you before work begins, and any part you do not want done is left out. The plan says what will be treated, what will be monitored and what the technician could not reach.
This applies when the colony is the Formosan species, which Clemson counts as established along this coast and concentrated in the coastal belt. Because the species is established across much of the county, the inspection looks at the whole structure rather than a single corner. The swarms come later in the year and in the evening, which is one of the clues a technician will ask about. See the Formosan treatment page for the details.
This applies when the signs point to the native species, which swarm in early spring, usually in the afternoon. Native colonies still reach the sub-floor framing through the same soil and damp. The work is aimed at the colony location and the moisture that supports it. More on this is on the native termite page.
Newer homes built on slab-on-grade have no crawl space, so the inspection and treatment move to the slab penetrations, expansion joints and the perimeter. In this market that is common in the post-1995 developments with young landscaping and new turf. The technician looks for soil contact against the slab edge and any wood framing that sits close to grade.
Most termite control calls are scheduled the same day when a technician is free, and you approve the price before any work starts.
North Charleston sits across Berkeley, Charleston and Dorchester counties, and the county lines run through the city. Two neighbours can be under different county programmes, but termite work does not stop at a county line. A colony under one house can reach the framing of the house next door through the same soil, so the inspection looks at the structure in front of it and at the conditions around it.
The city's housing is a mix of mid-century crawl-space houses, older raised frame buildings near the downtown and the Navy base area, and newer slab homes further out. Each kind needs a different inspection path. The old raised frame stock has exposed sub-floor framing and deep porches, while the crawl-space stock has the damp that feeds termites into the joists. Slab homes move the work to the perimeter and the penetrations, and the technician looks for soil and wood contact in each case.
This is a warm, humid coastal climate with no winter freeze deep enough to stop breeding, so termite activity does not pause for a season. Formosan swarms come from mid-May into July, often in the evening and drawn to lights, while native swarms appear in early spring. The timing of a swarm is useful information, and the more precisely you can describe it, the more useful the inspection will be. Tidal flooding and heavy rain can also wet the ground under older houses, which is one more reason the crawl space gets a close look.

A pest control quote in North Charleston depends mostly on the house: its footprint, whether it sits on a crawl space or a slab, how much of the sub-floor and perimeter a technician can reach, and the species and scope of the work.
Formosan subterranean termites were introduced into Charleston in the mid-1950s and are now established along the coast.
The CL-100 is South Carolina's official Wood Infestation Report, covering visible insect infestation and damage.
In South Carolina, pest control is licensed by the Department of Pesticide Regulation at Clemson University, not by a standalone licensing board.
A vented crawl space in coastal South Carolina can hold more moisture than its vents suggest.
Yes, and it matters for the treatment. Formosan subterranean termites are an introduced species that Clemson counts as established along this coast, while native subterranean termites are the local species that have always been here. Native swarms appear in early spring, usually in the afternoon, and Formosan swarms come later, in the evening. A technician will ask about the time of day for that reason.
Not always. Subterranean termites often stay inside the wall or the framing and build mud tubes on the outside of the structure. Hollow-sounding wood, blistered paint, and a musty smell in the crawl space can be signs before anything is seen. An inspection under the house is usually the most useful next step.
The length depends on the size of the house, the amount of access to the crawl space or slab edge, and what is found. A first inspection is usually a longer visit than a follow-up. The technician will tell you what the visit covers before starting. Visits are scheduled as a technician is available, and a same-day visit is possible when one is free.
Yes. Slab homes have no crawl space, but termites can still reach the structure through cracks, utility penetrations, soil in contact with the slab edge, and wood framing that sits close to grade. Newer developments often have young landscaping and new turf, which can bring soil right up to the foundation. The inspection looks at those points.
They are different problems that often appear together. Moisture in the crawl space can cause wood decay and attract termites, and termites can make a damp space worse by opening new paths for water. Clearing the moisture source is part of most plans, so the technician will look at the ground, the vents and the ducts as well as the termites.
Describe what you saw, where you saw it and when. Mention any swarms, the time of day, any mud tubes, and any soft or hollow wood. Tell them whether you are buying or selling, and whether you already have a termite contract with another company. That information helps the inspection start in the right place.
