A very heavy evening swarm at lights
Large numbers of pale golden swarmers around porch and street lights after dark in the warm months is a pattern worth having identified rather than dismissed as ordinary flying ants.
The reason SC termite work is different
Formosan Termites in Horry County: What Is Verified
Soil activity year-round on the coast, with evening swarms in the warm months
The gist
Formosan subterranean termites were introduced to South Carolina and are not native. Clemson entomologists list them as established in sixteen counties, and Horry is one of them, which puts the Conway area inside the documented range. Their colonies are far larger than the native species, they can build carton nests above ground, and that combination changes how a local termite inspection has to be done.
Diagnosis
How to tell
Any one of these is worth an inspection.
Hard gritty material inside a void
Carton nest material packed into a wall cavity, a hollow door frame or around a leaking pipe. It is a Formosan hallmark and it means the colony can hold its own moisture away from the soil.
Damage with no tube to the ground
Active galleries in an upper floor, an attic or a soffit with no visible soil connection is exactly the scenario that separates this species from the native one and the reason inspections here go higher up.
Tubes on a tree in the yard
They infest living and dead trees as well as structures, so mud work on a trunk, or a hollow sounding limb, can indicate a colony on the property before the house is involved.
Blistered paint over soft trim
A bulge that feels papery and gives under light pressure often covers a gallery. Because colonies are large, damage in a single season can be more noticeable than with native termites.
Why this one turns up here
This is verifiable rather than a scare story. Clemson lists Formosan termites as established in sixteen South Carolina counties including Horry, alongside neighboring Georgetown, and points out that a county appearing on that list does not mean uniform distribution across it, only that established infestations have been documented in some locations. So the correct way to read it for Conway is a real, documented local possibility that an inspector should be looking for, rather than something certain to be present on any given property.
The conditions on this coast suit them. Warm soil almost the whole year, high humidity, a high water table and abundant dead wood in trees, stumps and landscape timbers all support large colonies. Coastal construction adds the rest: crawl spaces that stay damp, wood in soil contact, and the plumbing and roof leaks that let a colony hold moisture inside a wall. Storm damaged trees left standing after a hurricane season also provide undisturbed wood close to houses, which is not something a drier inland market has to think about.
That risk isn't confined to Conway proper, either: the same colonies move through Carolina Forest, where wetland preserves and neighborhood stormwater ponds along River Oaks Drive keep soil moisture high year-round, and out toward Carolina Forest Boulevard where newer construction still backs up to undisturbed timber. Formosan activity found near the Carolina Bays Parkway corridor is the same species the licensed pros we connect you with confirm on older Conway lots, just working a wetter, woodier stretch of ground.
We deal with this across Conway and the surrounding towns, Litchfield Beach, Atlantic Beach and Briarcliffe Acres included.

What it gets mistaken for
Native subterranean termite swarmers. Size and color are the practical tells during a swarm. Clemson's comparison puts the Formosan swarmer at around half an inch and golden brown, against roughly three eighths of an inch and dark for the native species, and Formosan flights are typically in the evening and heavily attracted to lights. Under a lens there are head and wing hair differences that a lab or an experienced inspector uses. If a swarm has been collected, keeping a few specimens in a bag rather than vacuuming them all up makes proper identification possible, and the identification matters for how the property gets treated.
What treatment actually involves
Clemson's guidance is worth repeating plainly, because it cuts through a lot of marketing: the same control products and strategies used for native subterranean termites work on Formosan termites, and pest management professionals in the coastal counties have been protecting homes from them for decades. So the products are not exotic. What changes is thoroughness. Because the colony is bigger and can nest above ground, the inspection cannot stop at the crawl space; it has to cover wall voids, upper floors, attic framing, roof leaks, plumbing chases and the trees on the property.
In practice that means treatment is built to handle both routes. Soil work still matters, whether that is a continuous liquid treated zone or a monitored in ground bait system, and any above ground nest found gets treated directly in the void it occupies. Correcting moisture is not optional here, because a carton nest holding its own water is what allows a colony to survive away from the ground. There is also a disclosure point: South Carolina regulation requires that the presence of Formosan subterranean termites be disclosed when an active infestation is found in a structure, so identification is a matter of record and not just a technical detail. Ongoing inspection and a clear written agreement matter more with this species than with any other pest in the file.
Nobody needs a schedule for a formosan termites problem with an obvious start and an obvious end. Anyone who says otherwise is working from a sales sheet.
| What you are looking at | The fit |

| One place, one cause, spotted early | A single visit |
| A pattern rather than an incident | Cover through the year |
| Anything set up inside the structure itself | Both: the animal and the hole |
Where DIY works and where it does not
There is no sensible do it yourself version of this one, and that is not a sales line. Colony size, the ability to nest above ground and the fact that damage happens inside sealed framing all put it beyond retail products. What a homeowner can usefully do is remove the fuel and the water: get stumps, storm damaged limbs, buried lumber and old landscape timbers off the property, keep mulch below the siding line, fix roof and plumbing leaks quickly, and dry the crawl space out. Keep a few swarmers in a sealed bag if a flight happens, since identification changes the plan. Then get the structure inspected rather than guessing, because with this species the cost of being wrong is structural.
Roughly what it runs
A formosan termites job around here tends to sit between an estimated $449 and $1400. Which end depends on the house rather than on the insect. Having somebody look costs nothing, and you see the number in writing first. See the pricing guide for the complete set of ranges, and this one is handled under Termite Control & Inspections.

Questions & Answers
Frequently Asked Questions
Are Formosan termites definitely in Conway?
They are documented in Horry County by Clemson, which is the honest way to put it. Clemson's own wording is that a county on the list has had established infestations in some areas, not that the species is spread uniformly across it. So the correct expectation for a Conway property is that Formosan termites are a genuine local possibility an inspector should be checking for, and that identification during a swarm is worth doing properly.
Does a Formosan infestation need a different product?
Clemson's position is that the same products and strategies used against native subterranean termites work on Formosan termites, and that coastal professionals have been doing this successfully for a long time. What genuinely differs is scope and diligence: a larger colony, the possibility of an above ground nest with no soil connection, and therefore an inspection that covers wall voids, upper floors and attic framing as well as the crawl space.
Can they really get in without touching the soil?
Yes, and that is the single most important practical difference. They build a hard carton nest from chewed wood and soil that retains moisture, which lets a colony live in a wall void, an attic or a tree without a continuous connection to the ground. It is why finding no mud tubes at the foundation does not clear a property, and why a roof or plumbing leak is a termite issue here and not only a repair issue.
Do I have to tell a buyer if I have had them?
South Carolina regulation requires the presence of Formosan subterranean termites to be disclosed when an active infestation has been found in a structure, so it is a matter of record rather than discretion. Beyond that, disclosure obligations in a sale come from state real estate rules and your contract, so talk to your closing attorney or agent. Keep the inspection reports, the treatment records and the agreement paperwork together, because that documentation is what reassures a buyer.
