- Insurance usually doesn’t cover termite damage.
Homeowners, landlords and anyone buying or selling a house in Apex, whether you've spotted something or just want to know what to watch for.
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 Apex, but they move deeper and keep feeding under heated homes.
- 1Dry hexagonal pellets under window frames or eaves.
- 2Doors and windows that suddenly stick.
- 3Small kick-out holes in exposed wood.
- 4Live pale insects inside a broken mud tube.
- 5Sagging or spongy floors near exterior walls.
- 6Screwdriver sinks easily into sills or trim.
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.

A slow leak under a sink keeps the wood damp, and damp wood is exactly what termites are looking for.Which termites live around Apex.
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. The termite you're most likely to meet in Apex is the eastern subterranean termite.
Local termites conditions in Apex.
A provider who works Apex 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. Apex 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. Across Apex, 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 Apex usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Apex'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 downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.When termites swarm here.
Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves. Across Apex, eastern subterranean termites usually swarm from April through May, typically on a warm, sunny day after rain. Across Apex, 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.
Where to look around your house.
The same advice applies across the area, from Apex out to Holly Springs and Cary. A lot of houses around Apex 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.
A year of termites in Apex.
- Spring: swarm season. Across Apex, expect it from April through May. Check windowsills and light fixtures for wings. - Summer: with highs around 89°F in Apex, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 46 inches of rain a year in Apex, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Apex, before swarm season starts.
What happens at an inspection.
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. They'll also go into the crawl space.
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.
Keep kids and pets inside while the Apex crew applies the product, and ask how long to stay off treated soil. In North Carolina, native species begin swarming in late winter and continue into September or October, usually during the day on warm days following rain (NC State). Drill holes in slabs or patios get patched afterward. Prep is light for liquid treatments and bait stations. Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines.
Mulch and termites.
Pull mulch back from the foundation and keep the layer thin. A dry gap along the house makes mud tubes easier to spot; in Apex that means extending downspouts and pulling mulch back from the slab. Wood chips touching the siding trap the moisture termites are after.
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
- Number of bait stations required.
- Attached garages, decks, and additions.
- Local labor rates and licensing requirements.
- Warranty type: retreatment only or damage repair.
- Annual renewal and monitoring fees.
- Cubic footage under the tent for fumigation.

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
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.
Termites in Apex
Most houses will see termites at some point. With summer highs around 89°F, Apex's humid subtropical climate decides when local termites are busiest. A typical home in Apex is worth around $525k, which puts a few hundred dollars for an inspection and prevention in perspective. Apex gets about 46 inches of rain a year, and average humidity sits near 71%, so the soil around foundations rarely dries out. Termite activity in North Carolina is above average.

When termites are busiest around Apex
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. NC State references state rules requiring drilling and treating attached slabs and voids near known activity. FDACS and UGA list NC among Formosan states.

Simple ways to keep termites away
- Use borate-treated or pressure-treated lumber for repairs.
- Keep gutters clean so water does not pool.
- Caulk gaps around plumbing and utility penetrations.
- Keep the termite renewal contract current after treatment.
- Keep six inches between soil and siding or wood.
Keep the inspection diagram, treatment record and warranty together. Buyers and inspectors will ask for them later.Did you know?
Across Apex, some tropical termites grow fungus gardens inside the nest and eat the harvest.
Questions people ask
Can termites damage a house on a concrete slab?
They come up through expansion joints, plumbing gaps and small cracks. Inspectors check those spots first. Yes.
What does a WDI report include?
It also notes conditions that invite them, like wood touching soil. It only covers areas the inspector could reach. It lists any termites or damage found.
Do I need a termite inspection when buying a house?
Either way, it's cheap peace of mind. Ask your agent when it's due. Usually, yes. Many lenders ask for a wood-destroying insect (WDI) report.
Do I have to leave my house during termite treatment?
Fumigation is different. Everyone leaves for two to three days, pets and houseplants included. Not for a soil treatment or bait stations.
Are termite baits or liquid treatments more common?
Across Apex, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Apex, 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 Apex, the usual culprit is the eastern subterranean termite.
