North Charleston had 114,852 people at the 2020 census. The city spreads across Berkeley, Charleston and Dorchester counties, so one address can sit in a different county from its neighbor two streets over. Much of its land and housing follows from the former Charleston Naval Base, decided for closure by BRAC in 1993 and shut in 1996. The base tract on the Cooper River is still being redeveloped as the Navy Base Redevelopment District.
Housing runs from 1940s to 1960s base-era cottages and small masonry homes along Rivers Avenue and Dorchester Road, out to 1990s-and-later subdivisions toward 29420. A good number of the older houses sit over vented crawl spaces, and that shapes much of the work here. Newer homes may be built on a slab with no sub-floor to inspect, so the first question on a call is usually what the house is built on. Fire ants are part of the picture too. South Carolina lies entirely within the federal fire ant quarantine zone, and moving regulated items such as soil, sod and nursery stock out of the zone requires certification, because fire ants travel easily in them.

Clemson HGIC places Formosan termites in the Charleston area since the mid-1950s, so this is a treatment question here rather than a rare case.
Native subterranean termites swarm in early spring, usually in the afternoon, which is the first sign many North Charleston homeowners see.
A CL-100 is the state's official report of visible infestation and damage, and it is often needed when a North Charleston home is sold.
Many North Charleston houses sit over vented crawl spaces, where humid coastal air can condense on cold ducts and joists.
Charleston County runs an organized larviciding and spraying program, and most of the breeding that matters is in containers around the home.
Local weather drives activity here: heat, humidity and rain change what shows up week to week.
Clemson HGIC says Formosan subterranean termites were introduced into South Carolina in the 1950s and have been in the Charleston area since the mid-1950s. The same source notes infestations in many parts of Charleston County, concentrated in coastal areas from Charleston south to Beaufort. People are the main cause of their spread, mostly by moving infested material such as old railway ties. A swarm alone does not tell you how far an infestation has gone, so the first step is an inspection.
Native subterranean termites swarm in early spring, usually in the afternoon. Formosan swarms come later, from mid-May to July, often in the evening, drawn to lights. One newspaper account put Formosan emergence in a narrower late-May to early-June window, and sources differ on the start, so a swarm seen in late May is worth reporting either way. Drywood termites are a separate case. They nest inside the timber itself with no soil contact, so a soil barrier does not reach them.
'Palmetto bug' is an unofficial name. For some South Carolinians it means the American cockroach, and along the coast it often means the smokybrown. Clemson HGIC says more than 15 kinds of cockroach are found in South Carolina, but only a few get into homes. The most serious health problem it links to them is an allergic reaction to shed skin and droppings, rather than disease carried by the insect. Clemson's serious state pests are the American, smokybrown and German cockroaches.
The American is the largest of the three, reddish-brown, with a pale figure-eight marking behind the head, and is more often seen running than flying. The smokybrown is dark mahogany and shiny, common outdoors in leaf litter, shrubs and wood piles, and a strong flier drawn to lights. The German cockroach is small and tan with two dark stripes behind the head. It keeps to kitchens and bathrooms and does not fly, despite having wings. Telling them apart matters, because where they hide and how they move are different. For outdoor and indoor cases, see palmetto bug and smokybrown cockroach control.
Charleston County treats larvae in standing water from the air and adults by ground spraying. It posts aerial and ground schedules on its mosquito control website, and it chooses where to spray using surveillance equipment and reports from the public. The county deploys up to 30 traps across the county and tests for West Nile, eastern equine encephalitis and St. Louis encephalitis. Reports from residents are useful and can go to Charleston County Mosquito Control. No county response time is promised here.
The Asian tiger mosquito is the most common daytime biting mosquito in the Carolinas, according to Clemson HGIC. Its larvae develop in standing water in containers such as rain gutters, bird baths, flower pots, tires, barrels, boats, tarps, cans and garden pools, rather than in natural wetlands. Eliminating breeding sites is the homeowner's best control. HGIC notes that nighttime truck fogging often does not control this species, because it is mainly active in daylight. Large bodies of water should be treated only by mosquito control professionals. If mosquitoes persist after you have reduced breeding on your own property, SC DPH advises contacting your local mosquito program. For more, see mosquito control and what the Charleston County mosquito program does.
The mechanism is simple. In a warm, humid coastal climate, surfaces inside an air-conditioned house, such as ducts, joists and sub-floor framing, can sit below the dew point of the outside air. Humid air that enters a vented crawl space then condenses on them. Sustained damp feeds wood-decay fungi and draws termites to the sub-floor. The City of North Charleston's own page gives average precipitation of about 50 inches for the Charleston International Airport area and describes the local climate as temperate to subtropical.
There is no winter kill, so breeding continues through much of the year. A city climate summary and an older Charleston normals summary give a first freeze in early December and a last freeze in late February, a growing season of about 294 days. Tidal flooding is rising too. NOAA's 2022 outlook recorded 7 high-tide flood days at Charleston in 2021 and projects 70 to 90 a year by 2050, counting days above roughly 1.75 to 2 feet over normal tides. Low-lying, sandy ground that is poorly drained in places can hold that moisture against the foundation.

Clemson HGIC says Formosan subterranean termites have been established in the Charleston area since the mid-1950s and are present in many areas of Charleston County. They spread mainly when people move infested material. No neighborhood is presented here as having more of them than another, because no source gives rates by area.
Sources disagree on whether the regulation sets a validity period, so this page does not state one. In practice, lenders and closing attorneys, not the regulation, usually set the timing, so ask yours. The report covers visible infestation and damage from insects and decay. See the CL-100 wood infestation report.
Yes. The price is explained and approved before any work starts. It depends on house size and footprint, whether the house sits on a crawl space, pier or slab, access to the sub-floor and the full perimeter, the species and scope of the work, whether a CL-100 is needed for a sale, and the number of structures. No price is quoted on this page.
