Anyone in Cary who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
What to look for
Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs. 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.

Why it’s worth acting soon

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. For Cary homes, 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.
A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.Which termites live around Cary.
Formosan termites have turned up in parts of North Carolina. They're less common. Their colonies are much bigger, though. 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.
When termites swarm here.
For Cary homes, eastern subterranean termites usually swarm from April through May, typically on a warm, sunny day after rain. For Cary homes, 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. Swarm season is when termites show themselves.
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.
- 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. - Spring: swarm season. For Cary homes, 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.
Ways to keep the cost down.
- If you already have a warranty, keep the renewal current. - Book before swarm season, when schedules fill up. - Get two or three quotes, and compare what each one covers. - Fix leaks and drainage first. Moisture brings termites back. - Ask about both bait and liquid options for your house.
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?
- Debris: termites leave mud. Carpenter ants leave sawdust. - 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.
Getting ready for treatment day.
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. 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.
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.
- 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? - Which termites did you find, and where? - What product or system will you use? - Is the whole foundation treated, or just one spot?
What affects the price
- Time of year and how booked up local companies are.
- Species: subterranean, drywood, or Formosan.
- Liquid barrier versus bait station system.
- Annual renewal and monitoring fees.
- Wells, drains, or water features limiting chemical use.
- Cubic footage under the tent for fumigation.
- Attached garages, decks, and additions.
- Extent of existing damage needing repair.

What's your biggest concern about termite control costs?
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
Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house. 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.

Simple ways to keep termites away
- Check the foundation for mud tubes every spring.
- Paint or seal exposed exterior wood.
- Install a vapor barrier over crawl space soil.
- Set deck and porch posts on concrete, not soil.
- Ventilate crawl spaces and control humidity.
- Never leave form boards or scrap lumber in the soil.
Keep the inspection diagram, treatment record and warranty together. Buyers and inspectors will ask for them later.Did you know?
For Cary homes, some tropical termites grow fungus gardens inside the nest and eat the harvest.
For Cary homes, termites have been chewing wood for well over 100 million years, since the age of the dinosaurs.
Questions people ask
Is a bait system cheaper than a liquid treatment?
A liquid barrier has no monthly checks. Ask for both prices. Not usually upfront. For Cary homes, bait costs about the same to install, plus a yearly monitoring fee.
How much does annual termite renewal cost?
It keeps the warranty active and includes a yearly check. Letting it lapse usually ends the warranty. Usually $150–$400 a year.
Does homeowner insurance pay for termite damage?
Most policies treat termite damage as preventable. That's why catching it early matters. Usually not.
How much does termite fumigation cost?
It's mainly for drywood termites. Most homes around Cary never need it. Usually $1,200–$4,000, often $1–$4 per square foot.
Are mud tubes always a sign of active termites?
Break off a piece and check back in a week. If it's rebuilt, they're active. Not always. Old tubes can stay on a wall for years.
What is the difference between subterranean and drywood termites?
Drywood termites live inside the wood and leave tiny pellets. Around Cary, the subterranean kind causes most problems. Subterranean termites live in soil and build mud tubes.
Is termite treatment safe for kids and pets?
Bait stations are locked and buried. Ask for the label and follow any re-entry times. Used according to the label, yes. Soil treatments stay in the ground.
Are termite baits or liquid treatments more common?
For Cary homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Cary homes, 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.
