Homeowners, landlords and anyone buying or selling a house in Corpus Christi, 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. Winters around Corpus Christi stay mild, with average lows near 47°F, so colonies keep feeding all year. 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.
- 2Dry hexagonal pellets under window frames or eaves.
- 3Crumbling baseboards behind furniture.
- 4Tiny pinholes in drywall rimmed with mud.
- 5Doors and windows that suddenly stick.
- 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.

Treatment options and typical costs
Termite Inspection and WDI Report
$75–$250
The inspector checks the foundation, garage, attic and damp spots. Bring up anything you’ve noticed.
- Time
- 60–120 minutes
- Best for
- Every job, real estate closings, and yearly peace of mind
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year
Baiting is slower than a liquid barrier but reaches deeper colonies. For a Corpus Christi home on a well or with a finished slab, it is often the cleaner option.
- Time
- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Localized Wood, Foam, and Borate Treatment
$250–$1,500
Foam termiticide is injected into wall voids liquid cannot reach. In Corpus Christi this pairs well with a soil barrier around tricky slab construction.
- Time
- 1–3 hours
- Best for
- Small drywood spots, wall voids, and exposed framing
Fumigation for Drywood Termites
$1,200–$4,000 (often $1–$4 per square foot)
Fumigation tents the house and fills it with sulfuryl fluoride gas. For Corpus Christi homes with drywood termites in several areas, it is the only way to reach every gallery.
- Time
- 2–3 days including tenting and aeration
- Best for
- Widespread drywood termites throughout a structure
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.How treatment works on a typical Corpus Christi home.
In Corpus Christi, on a slab, the crew treats the soil along the outside walls. Under patios and garage floors, they drill small holes. Treatment goes in through the holes, which get patched afterward. 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.
Which termites live around Corpus Christi.
The termite you're most likely to meet in Corpus Christi is the eastern subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture. Formosan termites have spread into parts of Texas too. Their colonies dwarf native ones. Inspectors take them seriously. Drywood termites turn up now and then, mostly in older wood. Look for tiny piles of hard, sand-like pellets.
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.
Swarm season is when termites show themselves. In Corpus Christi, eastern subterranean termites usually swarm from February through April, typically on a warm, sunny day after rain. Formosan termites in Texas swarm later, from late April into June. Look for them on warm, humid evenings around porch lights. Drywood termites swarm on spring and summer evenings, often near 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.
Many homes in Corpus Christi sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks. Check the garage edges and behind baseboards. Look where pipes come through the floor. Outside, watch for mud tubes behind shrubs. Keep soil and mulch below the slab edge.

In Corpus Christi, expect it from February through April. Check windowsills and light fixtures for wings.
What happens at an inspection.
Photos help. Afterward, ask them to show you what they found. A moisture meter and a probe help them find hidden activity. On a slab, they focus on joints, cracks and pipe gaps. Inside, they check the garage, baseboards, plumbing gaps and the attic. They check the foundation, the soil line and nearby wood. The inspector walks the outside of the house first. Most inspections take an hour or two.
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.
Any drill holes in a slab or patio get patched. Ask how long to stay off treated soil. Keep pets and kids inside while the crew works outside. Mark sprinkler heads and any buried lines. Move stored boxes away from garage walls. Clear a path along the outside walls. Soil treatments and bait stations need little prep.
Mulch and termites.
Wood chips right against siding hold moisture termites like. A dry strip along the house lets you spot mud tubes. Keep mulch thin and pull it back from the foundation.
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
- Whole-house fumigation versus spot treatment.
- Extent of existing damage needing repair.
- Annual renewal and monitoring fees.
- Wells, drains, or water features limiting chemical use.
- Cubic footage under the tent for fumigation.
- Linear feet of foundation to be treated.

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
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.

When termites are busiest around Corpus Christi
Swarms begin in January–February in South Texas and not until April or May in the Panhandle (Texas A&M).
Texas A&M identifies the eastern subterranean and Formosan subterranean termites as the two economically important species. Termites enter via wood in direct contact with soil and by building shelter tubes over or through foundation cracks; modern termiticides provide approximately 5 years of protection and licensed professionals are recommended.

Simple ways to keep termites away
- Extend downspouts so water drains away from walls.
- Remove tree stumps and buried wood near the house.
- Trim shrubs so foundation walls stay visible and dry.
- Use borate-treated or pressure-treated lumber for repairs.
- Keep gutters clean so water does not pool.

Questions people ask
How do I know if I have termites or flying ants?
Save one in a bag for the inspector. Ants have a pinched waist; termites don't. Termite wings are all the same length. Check the wings and the waist.
Will termites come back after treatment?
That's what yearly inspections and renewal plans are for. Treatments wear down and new colonies move in. They can.
Can I treat termites myself?
Store-bought sprays usually kill only what you see. It also needs even coverage around the foundation. The product must reach the whole colony. An active colony is harder. Prevention, yes.
What is the difference between subterranean and drywood termites?
Around Corpus Christi, the subterranean kind causes most problems. Drywood termites live inside the wood and leave tiny pellets. Subterranean termites live in soil and build mud tubes.
Do most homeowners know termites can damage their house?
In Corpus Christi, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In Corpus Christi, 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 Texas?
Around Corpus Christi, the usual culprit is the eastern subterranean termite.
