Reading the Dallas swarm calendar
Two species fly here on two very different schedules, and the difference is easy to observe without any expertise. February through April brings the native eastern subterranean swarm. University of Georgia places that species swarming from February through April, and Mississippi State describes native daytime flights from mid February to mid May. These happen in daylight, often on the first genuinely warm afternoon after rain, and they end with wings on windowsills. Later in spring the Formosan pattern begins. University of Georgia describes Formosan swarming from dusk until about midnight between April and July, and Mississippi State places their flights in late April through June, a few hours after sunset. Evening flights around exterior lights fit that description. So the two questions that matter are the month and the hour. A daytime March flight suggests native subterranean. A ten o'clock flight in May suggests Formosan and warrants a faster call. Save a few specimens in a jar. Where they emerged matters most of all: outdoors in the yard means the species is in the area, while indoors means the colony has reached the structure.
Treating a slab home in North Texas
Slab construction is the defining feature of termite work around Dallas, and it changes the job in specific ways. With no crawlspace, there is no way to look at the underside of the floor and no soil to reach from beneath. A barrier has to be continuous around and under the structure, which means trenching wherever exposed soil exists and drilling through concrete wherever it does not. Garage floors, front walks, driveways poured to the wall, and covered patios all typically require drill points. Expect noise and dust control during the work, and expect patched holes afterward. Ask in advance how holes in a garage or on decorative concrete will be finished. Brick veneer adds a second consideration. The cavity behind the brick is a protected vertical route, and a treatment plan should address the weep line rather than treating the visible wall as the boundary. Finally, ask about plumbing penetrations. Those are the classic slab entry points, and a plan that names them specifically is a plan someone thought about rather than priced from a template.
The foundation watering problem, and how to handle it
North Texas homeowners face a genuine conflict that most of the country does not. Clay soils shrink when they dry, and that movement pulls support away from a slab. The common response during a hot Dallas summer is to run soaker hoses or drip lines along the foundation to keep moisture steady. Given summer highs near 96F, that is a reasonable building maintenance decision. The termite side of the ledger is straightforward: a continuously wet strip of soil against the slab is prime foraging ground, and it sits directly against the structure you are trying to protect. The practical compromise is control rather than abandonment. Water on a timer for even, moderate moisture instead of long soakings. Set the hose or emitters slightly out from the slab edge rather than tight against it. Avoid bed edging that traps water in a channel along the foundation. Tell your inspector how and where you water. It frequently explains why activity turned up on one wall and not another, and it should influence how a treatment plan is designed rather than being discovered after the fact.
What the inspection covers on a Dallas property
Without a crawlspace to work in, a slab home inspection concentrates on edges, penetrations, and interior evidence. Outside, the inspector walks the full perimeter checking the exposed slab edge, the brick weep line, grade height against the wall, mulch depth, downspout discharge, irrigation and soaker hose placement, and any wooden fence, gate, or deck post contacting soil. Inside, they look at baseboards along exterior walls, door and window casings, the garage where slab meets framing, and any area near a slab plumbing line. Bathrooms, laundry areas, and water heater closets get closer attention. The attic gets a look for drywood evidence, which the pest brief places as a summer and fall issue in some regions. You should receive a diagram marking findings, a distinction between active infestation and previous evidence, and a written list of inaccessible areas. Stored belongings along a garage wall are a common blind spot, so move them beforehand. Ask the inspector to show you one finding directly. It teaches you what to look for during your own perimeter walks afterward.
Comparing two Dallas termite proposals
Two quotes for the same slab home can differ in ways the totals never reveal, so compare the components. Begin with identification. Ask each company which species they found and where. A Formosan finding and a native finding can justify different plans, and disagreement should be settled before you look at price. Then ask for the mechanics: linear feet treated, number of drill points, whether the garage, driveway, walkways, covered patio, and any addition are included, and how the brick veneer cavity is addressed. Compare protection expectations against a known baseline. Texas A&M puts modern termiticide protection at roughly five years, so a proposal implying much less deserves a question and one implying much more deserves an explanation. Compare follow up terms. Ask how many reinspections are included, what the annual renewal costs, and what happens if activity returns within the covered period. For bait proposals, get the service interval and renewal price in writing, since protection depends on continued servicing. Finally, confirm current Texas licensing for the company and the applicator performing the work.
