Homeowners, landlords and anyone buying or selling a house in Cary, whether you've spotted something or just want to know what to watch for.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 30°F slow termites near the surface around Cary, 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.
- 1Mud in cracks of subfloor or joists.
- 2Screwdriver sinks easily into sills or trim.
- 3Mud tubes running up foundation walls or piers.
- 4Termite activity reported at a neighbor's home.
- 5Piles of identical shed wings on windowsills.
- 6Layered, honeycombed wood packed with soil.
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.

The termite you're most likely to meet in Cary is the eastern subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture. Formosan termites have turned up in parts of North Carolina. They're less common. Their colonies are much bigger, though.
Local termites conditions in Cary.
Cary sits in a humid subtropical climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. In Cary, the area is mostly suburban, so termites pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by. An inspection in Cary usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Cary's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. A provider who works Cary and North Carolina every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options.
Mulch piled against the house and a dripping hose bib give termites moisture and cover. Pull mulch back and fix the drip.When termites swarm here.
Swarm season is when termites show themselves. In Cary, eastern subterranean termites usually swarm from April through May, typically on a warm, sunny day after rain. In Cary, formosan termites in North 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.
Where to look around your house.
A lot of houses around Cary are built over crawl spaces, and that's usually where termites start. 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 Cary out to Apex and Raleigh.
A year of termites in Cary.
- Spring: swarm season. In Cary, expect it from April through May. Check windowsills and light fixtures for wings. - Summer: with highs around 89°F in Cary, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 46 inches of rain a year in Cary, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Cary, before swarm season starts.
What happens at an inspection.
Most inspections take an hour or two. 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.
Termites or ants?
- 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. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth.
Getting ready for treatment day.
Soil treatments and bait stations need little prep. Clear a path along the outside walls. Move stored boxes away from garage walls. Mark sprinkler heads and any buried lines. Keep pets and kids inside while the crew works outside. Ask how long to stay off treated soil. Any drill holes in a slab or patio get patched.
Mulch and termites.
Keep mulch thin and pull it back from the foundation. A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like.
Questions to ask before you sign.
- 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 do I need to do before and after treatment?
What affects the price
- Wells, drains, or water features limiting chemical use.
- Warranty type: retreatment only or damage repair.
- Whole-house fumigation versus spot treatment.
- Cubic footage under the tent for fumigation.
- Local labor rates and licensing requirements.
- Annual renewal and monitoring fees.

What's your biggest concern about termites?
When to call for help
Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud. 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.
What you can do yourself
Store-bought sprays usually kill only the termites you see. It also needs even coverage around the entire foundation. The product has to reach the whole colony. Treating an active colony is harder. Keep firewood away from the house. Fix leaks and clear gutters. Pull mulch back from the foundation. Some of the work is yours.

Native species begin swarming in late winter and continue into September or October, usually during the day on warm days following rain (NC State).
The NC Official Wood-Destroying Insect Information Report 'is the only form that is legal for this purpose and is required on almost every residential structure sold', and must be issued by a licensee of the NCDA&CS Structural Pest Control Division.

Simple ways to keep termites away
- Extend downspouts so water drains away from walls.
- Caulk gaps around plumbing and utility penetrations.
- Paint or seal exposed exterior wood.
- Set deck and porch posts on concrete, not soil.
- Inspect used furniture for drywood pellets before bringing indoors.
- Seal cracks in the foundation and slab.

In Cary, termites have been chewing wood for well over 100 million years, since the age of the dinosaurs.
Questions people ask
Will termites come back after treatment?
They can. Treatments wear down and new colonies move in. That's what yearly inspections and renewal plans are for.
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.
Are mud tubes always a sign of active termites?
Not always. Old tubes can stay on a wall for years. Break off a piece and check back in a week. If it's rebuilt, they're active.
Can termites damage a house on a concrete slab?
Yes. They come up through expansion joints, plumbing gaps and small cracks. Inspectors check those spots first.
What are the signs of termites that homeowners miss?
In Cary, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In Cary, 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 North Carolina?
Around Cary, the usual culprit is the eastern subterranean termite.
