Anyone in Mount Pleasant who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 40°F slow termites near the surface around Mount Pleasant, but they move deeper and keep feeding under heated homes. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.
- 1Screwdriver sinks easily into sills or trim.
- 2Layered, honeycombed wood packed with soil.
- 3Mud in cracks of subfloor or joists.
- 4Crumbling baseboards behind furniture.
- 5Blistered or bubbling paint on wood surfaces.
- 6Damage found during a remodel or repair.
Why it’s worth acting soon
- Colonies grow and spread every year they go untreated.
- Damage hides behind drywall, flooring and trim.
- Homeowners insurance usually doesn’t cover termite damage.
- An active infestation can complicate a home sale.
- Formosan colonies are large and can do serious damage quickly.

- Colony elimination, wells and slabs, homes near water
Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
A soil barrier stops termites from reaching wood through the ground. For most Mount Pleasant homes with active subterranean termites, this is the fastest way to end feeding.

- Best for
- Active subterranean termites; fast knockdown around the foundation
Fumigation for Drywood Termites
$1,200–$4,000 (often $1–$4 per square foot)

Crawl spaces are where termites usually get in. Joists, piers and the sill plate should all get a close look.How treatment works on a typical Mount Pleasant home.
They also treat around piers and plumbing. Fix any moisture under the house too. Bait stations are the other main option. They're spaced every 10 to 20 feet. Termites carry the bait back to the colony. The stations are checked on a schedule, often every few months. With a crawl space, the crew treats soil outside and underneath.
Which termites live around Mount Pleasant.
It nests in soil and builds mud tubes to reach wood. It needs steady moisture. Formosan termites have spread into parts of South Carolina too. Their colonies dwarf native ones. Inspectors take them seriously. The termite you're most likely to meet in Mount Pleasant is the eastern subterranean termite.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.When termites swarm here.
Across Mount Pleasant, eastern subterranean termites usually swarm from March through May, typically on a warm, sunny day after rain. Formosan termites in South Carolina swarm later, from late April into June. Look for them on warm, humid evenings around porch lights. A swarm outside means a colony is nearby. A swarm inside usually means it's in the house. Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves.
Where to look around your house.
Take a flashlight underneath. Check the piers, the sill plate and the floor joists. Standing water or a musty smell needs fixing either way. The same advice applies across the area, from Mount Pleasant out to Charleston and North Charleston. A lot of houses around Mount Pleasant are built over crawl spaces, and that's usually where termites start.
A year of termites in Mount Pleasant.
- Winter: a good time to book an inspection in Mount Pleasant, before swarm season starts. - Spring: swarm season. Across Mount Pleasant, expect it from March through May. Check windowsills and light fixtures for wings. - Summer: with highs around 89°F in Mount Pleasant, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 51 inches of rain a year in Mount Pleasant, make sure gutters and downspouts carry water well away from the foundation.
What happens at an inspection.
The inspector walks the outside of the house first. They check the foundation, the soil line and nearby wood. Inside, they check the garage, baseboards, plumbing gaps and the attic. They'll also go into the crawl space. A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help. Most inspections take an hour or two.
Termites or ants?
- Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Wings: termite wings are all the same length. Ant wings aren’t. - Waist: termites are thick through the middle. Ants are pinched. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Debris: termites leave mud. Carpenter ants leave sawdust.
Getting ready for treatment day.
Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines. Keep kids and pets inside while the Mount Pleasant crew applies the product, and ask how long to stay off treated soil. In South Carolina, native subterranean species swarm in early spring, often in the afternoon; Formosan swarms mid-May to July, often in the evening, attracted to lights (Clemson). Drill holes in slabs or patios get patched afterward. Prep is light for liquid treatments and bait stations.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot, and with roughly 51 inches of rain a year in Mount Pleasant, keeping that strip dry takes real grading and gutter work. Wood chips touching the siding trap the moisture termites are after. Pull mulch back from the foundation and keep the layer thin.
Questions to ask before you sign.
- What do I need to do before and after treatment? - Which termites did you find, and where? - What product or system will you use? - Is the whole foundation treated, or just one spot? - What does the warranty cover, and for how long? - What does the yearly renewal cost?
What affects the price
- Amount of drilling through concrete and patios.
- Local labor rates and licensing requirements.
- Linear feet of foundation to be treated.
- Access to crawl spaces and attics.
- Attached garages, decks, and additions.
- Annual renewal and monitoring fees.

What's your biggest concern about termites?
When to call for help
Call if you see mud tubes, pellets or an indoor swarm. Hollow-sounding wood is another clue. Buying or selling? Get a wood-destroying insect (WDI) report either way. Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud.
What you can do yourself
Treating an active colony is harder. The product has to reach the whole colony. It also needs even coverage around the entire foundation. Store-bought sprays usually kill only the termites you see. Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house.

Simple ways to keep termites away
- Never leave form boards or scrap lumber in the soil.
- Keep gutters clean so water does not pool.
- Trim shrubs so foundation walls stay visible and dry.
- Paint or seal exposed exterior wood.
- Extend downspouts so water drains away from walls.
- Keep six inches between soil and siding or wood.
An inspection starts outside, with a flashlight along the foundation line where mud tubes show up first.Did you know?
Some African termite mounds stand more than 25 feet tall.
Across Mount Pleasant, when danger shows up, soldier termites bang their heads against the tunnel walls to warn the colony.
Questions people ask
How do I know if I have termites or flying ants?
Check the wings and the waist. Termite wings are all the same length. Ants have a pinched waist; termites don't. Save one in a bag for the inspector.
What does a WDI report include?
It lists any termites or damage found. It also notes conditions that invite them, like wood touching soil. It only covers areas the inspector could reach.
Is termite treatment safe for kids and pets?
Used according to the label, yes. Soil treatments stay in the ground. Bait stations are locked and buried. Ask for the label and follow any re-entry times.
How long does termite treatment take?
A liquid barrier takes half a day to a day. Bait stations take a few hours to install. Fumigation takes two to three days.
How long do termite bait stations take to work?
Usually several weeks to a few months. Termites have to find the stations first. Then the bait spreads through the colony.
Is termite fumigation common?
Across Mount Pleasant, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Mount Pleasant, a professional inspection looks for mud tubes, damaged wood, and swarming activity, and treatment targets the soil and the colony rather than just the visible wood.
Are termites common in South Carolina?
Around Mount Pleasant, the usual culprit is the eastern subterranean termite.
