The signs that actually mean termites
Subterranean termites work inside wood and inside soil, so by the time anything is visible from a hallway, the colony has usually been established for a while. These are the findings that matter, roughly in order of how much they should worry you.
Winged swarmers indoors
A cluster of dark, winged insects at a window in spring — or a scatter of discarded wings on a sill, in a bath, or around a light fitting — is the clearest signal there is. Swarmers are the colony's reproductive caste leaving to start new colonies. Indoors, they mean the colony is in or under the structure, not in the yard.
Mud tubes on foundations and piers
Pencil-width tubes of soil and saliva running up a stem wall, a pier, or the inside of a garage wall. Termites build them to cross exposed concrete without drying out. Break one open: live workers inside means an active route. A dry, empty tube may be old, but the only way to know is to keep watching it or have it checked.
Hollow or blistered wood
Tap door frames, baseboards and window trim with the handle of a screwdriver. Termite-damaged wood sounds papery and gives under pressure. Painted surfaces can blister or ripple where galleries run just beneath.
Doors and windows that suddenly stick
This one is ambiguous in Dallas, because seasonal foundation movement in Blackland clay does exactly the same thing. That is precisely why it is worth having checked rather than assumed: the same soil behaviour that racks your door frames also opens the routes termites use.
What treatment involves
A general pest inspection is not the same thing as a termite inspection, and an exterminator who handles quarterly pest work does not necessarily do termite treatment — it is a separate licence category in Texas. Ask which you are getting.
Two broad approaches dominate residential work in North Texas, and a good operator will explain which one they are proposing and why.
Liquid soil treatment
A termiticide is applied to the soil around and beneath the foundation, typically by trenching along the perimeter and drilling through slab, patio or driveway where the foundation cannot be reached from outside. The aim is a continuous treated zone that termites cannot cross undetected. On a slab home this is the most common approach and the reason quotes are usually priced by linear feet of foundation.
Baiting systems
Stations are installed in the soil around the structure and monitored. Foraging termites take treated bait back to the colony. Baiting is less disruptive than drilling through finished concrete and is often chosen where slab drilling would be difficult or where an ongoing monitoring relationship suits the property. It works on the colony's timescale rather than on yours, which is a real consideration if you are mid-sale.
Ask which one you are buying — and what comes after
Termite proposals usually bundle two separate things: the treatment itself, and an ongoing agreement covering monitoring, annual re-inspection and re-treatment terms. They are priced differently and they renew differently. Ask what the agreement covers, what it costs to renew, what voids it, and whether it transfers if you sell the house. Get all of that in writing before the first hole is drilled.
What this costs in Dallas
Full subterranean termite treatment on a typical Dallas single-family home commonly falls somewhere between $1,200 and $4,000, and larger or more complex properties go above that. The variables that move it most are the linear footage of foundation, whether the crew can trench freely or has to drill through concrete, whether the home is slab or pier-and-beam, and which method is used. These are typical local ranges, not quotes — the only real number comes from an inspection.
For a job in that price band, two or three written proposals is normal and sensible. Compare scope and agreement terms, not only the headline figure.
Why Dallas is termite country
Subterranean termites need soil contact and moisture, and North Texas gives them both alongside a long warm season. The Blackland Prairie clay under most of the city has a high shrink-swell capacity: it pulls back from foundations in drought and closes again when it rains, working cracks and joints open and shut year after year. Add irrigation running against a foundation, mulch piled above the slab line, or a flowerbed that buries weep holes, and you have moisture exactly where the colony wants it, right next to the wood it is looking for.
The practical takeaway is that termite prevention here is largely a drainage and grading exercise. Keep soil and mulch below the slab line, keep sprinkler heads pointed away from the foundation, fix the outside tap that drips onto the flowerbed, and keep firewood and lumber off the ground and away from the house.

Termite questions, answered plainly
How quickly do termites actually damage a house?
Slowly, in the sense that nobody loses a house over a season, and steadily, in the sense that a colony that has been feeding for three years has done three years of work. The urgency with termites is not that the ceiling is about to come down — it is that damage found today started long before today, and every month of waiting is more of it. That is a reason to get an inspection promptly, not a reason to accept a same-day decision under pressure.
Is a spring swarm inside the house an emergency?
It is the strongest evidence you will get, and it should trigger an inspection within days rather than months. It is not an emergency in the sense of evacuating the house. Collect a few of the insects or wings in a bag or a jar, photograph where they appeared, and keep that for the inspector — where swarmers emerged narrows down where the colony is.
Can I treat termites myself?
Over-the-counter products can kill the termites you can see, which is the part of the problem that matters least. A subterranean colony is in the soil and can number in the hundreds of thousands. Effective liquid treatment means establishing a continuous treated zone around and under a foundation, which needs equipment, product volume and a licensed applicator. DIY on a confirmed subterranean infestation generally costs you time you did not have.
Does homeowners insurance cover termite damage?
Standard homeowners policies in Texas generally exclude damage from termites and other insects, on the reasoning that it is a maintenance issue rather than a sudden accidental loss. Read your own policy and ask your carrier directly. We cannot tell you what your policy covers, and any pest control company that promises an insurance outcome is out of its lane.
Slab or pier-and-beam — which is worse for termites?
Neither is safe; they are different problems. A slab home gives termites cracks, expansion joints and plumbing penetrations to bridge, and treatment often means drilling. A pier-and-beam home gives them direct access to floor joists and sill plates from the piers, plus a crawlspace that holds moisture — but that crawlspace also makes the damage far easier to inspect. Older Dallas neighbourhoods with pier-and-beam construction tend to catch problems earlier for exactly that reason.
How often should a Dallas home be inspected?
Annually is the general recommendation in a high-pressure termite region, and it is what most ongoing termite agreements are built around. If you have no agreement and no history of activity, an inspection every year or two is reasonable — and one is effectively mandatory anyway when you sell, in the form of a WDI report.
Found mud tubes or spring swarmers?
Photograph what you found and where. A licensed inspector can tell you in one visit whether it is active. Calls may be recorded for quality and training.
