The short version
Most termite problems in Pasadena are eastern subterranean termites, and the usual fix is a liquid soil treatment or bait stations. Drywood termites need fumigation or wood treatment instead. Start with an inspection; $75–$250 is typical.
- Look for mud tubes, shed wings and hollow-sounding wood.
- Swarms usually show up from February through April.
- Drywood termites need wood treatment or fumigation instead.

- Insurance usually doesn’t cover termite damage.
Homeowners, landlords and anyone buying or selling a house in Pasadena, 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 Pasadena stay mild, with average lows near 44°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.
- 2Layered, honeycombed wood packed with soil.
- 3Termite tubes hanging down from ceilings or joists.
- 4Mud tubes running up foundation walls or piers.
- 5Sagging or spongy floors near exterior walls.
- 6Winged swarmers indoors, especially in spring.
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 Pasadena 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 Pasadena 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
Annual Renewal and Monitoring
$150–$400 per year
A renewal contract sends a technician back each year to re-inspect and touch up the treatment. Many liquid warranties stay valid only if renewal is kept current.
- Time
- 30–60 minutes per visit
- Best for
- Keeping a treated home protected after the initial job

Cardboard boxes stacked on a garage slab are termite food sitting right on their doorstep. Keep storage on shelves.Which termites live around Pasadena.
Look for tiny piles of hard, sand-like pellets. Drywood termites turn up now and then, mostly in older wood. Inspectors take them seriously. Their colonies dwarf native ones. Formosan termites have spread into parts of Texas too. It needs steady moisture. It nests in soil and builds mud tubes to reach wood. The termite you're most likely to meet in Pasadena is the eastern subterranean termite.
Local termites conditions in Pasadena.
A provider who works Pasadena and Texas 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. Knowing Pasadena'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. An inspection in Pasadena usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Around Pasadena, the area is mostly residential, 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. Pasadena sits in a local climate, and that sets the pace for termite activity here: the warmer months.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.When termites swarm here.
Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house. A swarm outside means a colony is nearby. Drywood termites swarm on spring and summer evenings, often near lights. Look for them on warm, humid evenings around porch lights. Formosan termites in Texas swarm later, from late April into June. Around Pasadena, eastern subterranean termites usually swarm from February through April, typically on a warm, sunny day after rain. Swarm season is when termites show themselves.
Where to look around your house.
The same advice applies across the area, from Pasadena out to Houston and Galveston. Keep soil and mulch below the slab edge. Outside, watch for mud tubes behind shrubs. Look where pipes come through the floor. Check the garage edges and behind baseboards. Many homes in Pasadena sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks.
A year of termites in Pasadena.
- Spring: swarm season. Around Pasadena, expect it from February through April. Check windowsills and light fixtures for wings. - Summer: with highs around 95°F in Pasadena, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 50 inches of rain a year in Pasadena, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Pasadena, 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. On a slab, they focus on joints, cracks and pipe gaps. 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?
- Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Debris: termites leave mud. Carpenter ants leave sawdust. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
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. Keep kids and pets inside while the Texas crew applies the product, and ask how long to stay off treated soil. In Texas, swarms begin in January–February in South Texas and not until April or May in the Panhandle (Texas A&M). Drill holes in slabs or patios get patched afterward.
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 Texas 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 do I need to do before and after treatment? - What does the yearly renewal cost? - What does the warranty cover, and for how long? - Is the whole foundation treated, or just one spot? - What product or system will you use? - Which termites did you find, and where?
What affects the price
- Whole-house fumigation versus spot treatment.
- Warranty type: retreatment only or damage repair.
- Amount of drilling through concrete and patios.
- Annual renewal and monitoring fees.
- Species: subterranean, drywood, or Formosan.
- Linear feet of foundation to be treated.

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
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.
Termites in Pasadena
An annual inspection is common sense here. Texas is one of the most termite-active states in the country. Like nearby Houston, Pasadena gets about 50 inches of rain a year, which is plenty for subterranean termites along any damp side of the house.

When termites are busiest around Pasadena
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
- Inspect used furniture for drywood pellets before bringing indoors.
- Keep gutters clean so water does not pool.
- Keep the termite renewal contract current after treatment.
- Fix leaking hose bibs, faucets, and pipes promptly.
- Address wood-to-soil contact at steps, fences, and trellises.
- Set deck and porch posts on concrete, not soil.
An inspection starts outside, with a flashlight along the foundation line where mud tubes show up first.Did you know?
Around Pasadena, when danger shows up, soldier termites bang their heads against the tunnel walls to warn the colony.
Around Pasadena, termites are closer cousins to cockroaches than to ants, despite the old nickname white ants.
Questions people ask
How do I know if I have termites or flying ants?
If you are still unsure, a Pasadena inspector can identify a sample in seconds. Flying ants have a pinched waist, uneven wings, and elbowed antennae. Termite swarmers around Pasadena have a broad waist, four wings of equal length, and straight beaded antennae. Look at the waist, the wings, and the antennae.
Will termites come back after treatment?
Treatment ends the current infestation, but termites remain in the soil around Pasadena, Texas neighborhoods. Keeping mulch and wood away from the foundation, fixing leaks, and keeping the renewal contract current are how Pasadena homeowners stay protected long term.
Does fumigation kill subterranean termites too?
If there are mud tubes too, a pro in Pasadena will pair fumigation with a liquid or bait treatment around the foundation. The gas reaches every gallery in the wood of a Pasadena, Texas house but not the ground beneath it. Tenting is a drywood tool.
Can I treat termites myself?
If you want to do something today, pull wood and mulch away from your Pasadena foundation while you book the inspection. Professional baits and non-repellent termiticides do. Spot sprays and stakes do not reach the colony. DIY termite control in Pasadena usually ends with a bigger bill later.
How long does termite treatment take?
A Pasadena pro should give you a timeline in the proposal. Bait systems keep working for months after a short installation. A full liquid barrier takes most of a day. Spot treatments take an hour or two. It depends on the method chosen for your Pasadena home.
Are termites common in Texas?
Around Pasadena, the usual culprit is the eastern subterranean termite.
