Most Widespread Termite in South Carolina
Eastern Subterranean Termites in Mount Pleasant, SC
Year-round underground activity; swarmers late January through April
Short answer
Eastern subterranean termites are the most widespread termite species in South Carolina and are present throughout Charleston County. They swarm during the day in late winter to early spring, often after rain. Colonies are smaller than Formosan colonies but still capable of significant structural damage over time.
Identification
Signs to look for
What normally prompts the call.
Daytime swarmers near windows or on window sills in late winter
Winged reproductives leaving to start new colonies. Discarded wings near windows are a common first sign.
Wood that sounds hollow when tapped
Interior wood consumption leaving a thin shell. Most visible in floor joists and sill plates in crawl spaces.
The local reason behind it
Eastern subterranean termites are native to South Carolina and present statewide. No part of Charleston County is outside their range.
Homes on crawl space foundations with direct soil contact and homes with wood-to-soil grade contact are at highest risk.
Dunes West sits close to tidal salt marsh along the Highway 41 corridor, where damp, humidity-holding ground gives subterranean colonies an easy path to a foundation. Mount Pleasant shares that same moisture-heavy soil, and the licensed pros working this area see identical mud tubes on homes stretching out toward Awendaw and the Highway 17 North approach, wherever crawl spaces stay damp and untreated wood sits low enough to touch the ground.
The same job gets done in West Ashley, Hanahan and Folly Beach, and everywhere else covered around Mount Pleasant.

- Range
- Statewide across South Carolina
- CL-100 relevance
- Any active infestation or prior damage must be disclosed on a CL-100 inspection report
- Active period
- Year-round underground activity; swarmers late January through April
- Typical treatment
- an estimated $449–$1400
Or is it something else?
Formosan subterranean termites. Eastern subterraneans swarm during the day in late winter to early spring; Formosans swarm at night in late spring. Eastern swarmers are slightly smaller.
The treatment, step by step
Annual termite inspection under a current termite bond
Liquid soil termiticide treatment
In-ground bait station program
The honest split is simple: contained and caught early is a single visit; recurring outdoor pressure is a plan.
| The case | Usually the right call |
|---|---|
| A single active problem, found early | Single visit |
| Something that keeps reappearing | Recurring plan |
| A problem in wall voids, an attic or a crawl space | Treatment, then closing the way in |
Before you call anyone
Subterranean termite colonies are underground and beyond the reach of consumer products. A SCDPR-licensed inspection and treatment is the required approach.
Putting a number on it
A guide figure for eastern subterranean termites locally is an estimated $449 to $1400, which is a band rather than a quote. The inspection costs nothing and the real number goes in writing before anyone starts. Estimated bands, and what pushes a job up or down them, are set out on the pricing guide, and the service that handles this is Termite Inspection.

Questions & Answers
Frequently Asked Questions
How is a termite bond different from a warranty?
A termite bond is a service contract that includes annual inspections and coverage — either retreatment only, or retreatment plus repair — if termites are found active between inspections. A retreatment-only bond costs less but leaves repair costs to the homeowner.
My neighbor had a swarm. Should I be worried?
Eastern subterranean termites can travel significant distances underground. A swarm next door is a reasonable prompt for an inspection, especially if your home has not been inspected recently.
Does homeowners insurance cover termite damage?
Standard homeowners insurance policies in South Carolina do not cover termite damage, which is considered a maintenance issue. A termite bond with repair coverage is the primary financial protection available.
