Homeowners, landlords and anyone buying or selling a house in Durham, 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 Durham, 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.
- 1Wood that sounds hollow when tapped.
- 2Doors and windows that suddenly stick.
- 3Buckling laminate or warped hardwood flooring.
- 4Tiny pinholes in drywall rimmed with mud.
- 5Screwdriver sinks easily into sills or trim.
- 6Mud tubes running up foundation walls or piers.
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.

Prices are typical published ranges. Ask what’s included before you compare quotes.
Drywood termites can fly straight into attic framing through vents, so attics belong on the inspection list in warm climates.Which termites live around Durham.
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 Durham is the eastern subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture.
Local termites conditions in Durham.
An inspection in Durham usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Durham'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 Durham 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. Durham 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 Durham homes, the area is mostly urban, 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.
A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.When termites swarm here.
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. For Durham homes, eastern subterranean termites usually swarm from April through May, typically on a warm, sunny day after rain. For Durham homes, formosan termites in North Carolina swarm later, from late April into June.
Where to look around your house.
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 Durham out to Chapel Hill and Cary. A lot of houses around Durham are built over crawl spaces, and that's usually where termites start. Take a flashlight underneath.
A year of termites in Durham.
- Summer: with highs around 89°F in Durham, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 46 inches of rain a year in Durham, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Durham, before swarm season starts. - Spring: swarm season. For Durham homes, expect it from April through May. Check windowsills and light fixtures for wings.
What happens at an inspection.
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. 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.
Termites or ants?
- 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. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
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. Soil treatments and bait stations need little prep. Clear a path along the outside walls. Move stored boxes away from garage walls.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like. Keep mulch thin and pull it back from the foundation.
Questions to ask before you sign.
- 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? - Which termites did you find, and where?
What affects the price
- Slab, crawl space, or basement construction.
- Annual renewal and monitoring fees.
- Attached garages, decks, and additions.
- Species: subterranean, drywood, or Formosan.
- Cubic footage under the tent for fumigation.
- Warranty type: retreatment only or damage repair.

What's your biggest concern about termites?
When to call for help
Termites leave mud. Carpenter ants leave clean tunnels and sawdust. It's also the cheapest termite service. Lenders often ask for one. Get a wood-destroying insect (WDI) report either way. Buying or selling? Hollow-sounding wood is another clue. Call if you see mud tubes, pellets or an indoor swarm.
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
- Keep gutters clean so water does not pool.
- Store firewood well away from the house, off the ground.
- Keep mulch at least a foot from the foundation.
- Paint or seal exposed exterior wood.
- Set deck and porch posts on concrete, not soil.
- Inspect used furniture for drywood pellets before bringing indoors.
Keep the inspection diagram, treatment record and warranty together. Buyers and inspectors will ask for them later.Did you know?
For Durham homes, a termite queen can keep laying eggs for 25 years or more.
For Durham homes, some tropical termites grow fungus gardens inside the nest and eat the harvest.
Questions people ask
Do I have to leave my house during termite treatment?
Not for a soil treatment or bait stations. Fumigation is different. Everyone leaves for two to three days, pets and houseplants included.
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.
Can I treat termites myself?
Prevention, yes. An active colony is harder. The product must reach the whole colony. It also needs even coverage around the foundation. Store-bought sprays usually kill only what you see.
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 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.
Do most pest control companies treat existing homes for termites?
For Durham homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Durham 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 Durham, the usual culprit is the eastern subterranean termite.
