The Blackland Prairie clay beneath every Dallas home is termite highway. Eastern subterranean termites cause more structural damage in Dallas County than storms, floods, and fire combined — and homeowner insurance doesn't cover it. Romex is DFW's locally managed, Sentricon®-certified termite team. We eliminate colonies, not just surface activity.

Dallas sits squarely on the Texas Blackland Prairie — a geological formation of deep, expansive clay soils that stretches from the Red River to San Antonio. This clay is the single biggest factor in DFW's termite pressure. It retains moisture for weeks after rainfall, creating ideal tunneling conditions for eastern subterranean termites. The clay also expands and contracts dramatically with seasonal moisture changes, creating foundation cracks that give termites direct entry into structures.
The DFW metro receives approximately 37 inches of rain annually — more than Austin — with intense spring storms in March through May that saturate the soil and trigger mass swarming events. Dallas homeowners routinely report finding translucent wings on windowsills and mud tubes on foundation walls within days of heavy rain. The Trinity River floodplain and White Rock Creek watershed create permanent moisture corridors that sustain massive colony networks.
Dallas's building stock amplifies the risk. Historic neighborhoods like Lakewood (1920s–1940s Tudor and Craftsman homes), M Streets, Oak Lawn, and Kessler Park feature pier-and-beam foundations with exposed wood near soil contact. Even newer slab-on-grade construction in suburbs like Frisco, McKinney, and Forney is vulnerable where builder-grade soil treatments have degraded after 5–7 years. The 2021 Winter Storm Uri complicated matters further — foundation shifts from freeze-thaw cycles opened new entry points that many homeowners haven't addressed.
Termite pressure varies across the DFW metro based on soil composition, home age, and proximity to waterways. Here's what our technicians see in the field.
Liquid soil treatments degrade faster in DFW's expansive clay — seasonal shrink-swell cycles break chemical barriers within 3–5 years. Sentricon® bypasses the soil entirely and targets the colony itself.
Our TDA-licensed inspector evaluates your foundation perimeter, identifies active mud tubes, moisture intrusion, and wood-to-soil contacts. In Dallas's expansive clay, we often install stations at 8-foot intervals (vs. the standard 10) near irrigation lines, AC condensate drains, and garden beds where moisture concentrates.
Subterranean termites forage through soil tunnels that can extend 300+ feet from the colony. In DFW's moisture-rich clay, foraging is especially aggressive after spring rains. The Recruit HD bait contains noviflumuron — a chitin synthesis inhibitor termites consume and share through trophallaxis (mouth-to-mouth feeding), carrying it back to the colony.
Noviflumuron prevents termites from molting. The effect cascades through the colony — workers, soldiers, reproductives, and the queen are all eliminated. Colony collapse typically occurs within 60–90 days. In Dallas's dense suburban developments with overlapping colony territories, Sentricon® often intercepts multiple colonies simultaneously.
Stations remain in the ground permanently and are checked quarterly. As DFW's northern suburbs (Frisco, McKinney, Celina) expand into former farmland, new colonies establish alongside new construction. The Sentricon® network intercepts them before they reach your home.
Pencil-width mud tubes on your foundation or interior walls. In Dallas, these often appear on the shaded north and east sides of homes. Check behind landscaping — dense plantings against foundations are the top concealment factor our technicians find in Lakewood and M Streets.
Translucent, equal-length wings shed by reproductive termites after mating flights. DFW's primary swarm season is March through May, triggered by warm days after rain. Finding swarmers inside indicates the colony is already established in or under the structure.
Subterranean termites eat wood from the inside out, leaving a paper-thin surface. Tap door frames, baseboards, and window sills — particularly in pier-and-beam homes in Kessler Park, Oak Cliff, and older Lakewood neighborhoods where framing contacts soil through pier blocks.
Dallas's expansive clay shrinks dramatically during summer droughts, then swells after rain. This cycle creates foundation cracks that serve as termite superhighways. After the 2022–2023 drought, we saw a surge in termite intrusion through foundation gaps across North Dallas.
Moisture from termite tunneling behind walls causes paint to bubble. This is commonly misdiagnosed as water damage in Dallas homes, particularly in bathrooms and kitchens where plumbing creates additional moisture that attracts foragers.
Advanced termite damage to floor joists causes sagging. Doors and windows that suddenly stick may indicate structural compromise. In older Dallas homes with pier-and-beam foundations, inspect wooden support beams in the crawl space for tunneling and frass.
Our technicians are positioned across the metroplex for fast response. Same-day inspections available for most communities.
Eastern subterranean termites are the dominant species across Dallas County. They thrive in the Blackland Prairie's heavy clay soils, which retain moisture and provide ideal tunneling. Formosan subterranean termites have been confirmed in pockets of East Dallas and southern Dallas County. Drywood termites are rare in DFW.
Costs vary by property size, foundation type, and severity. Romex offers free inspections with no obligation. Sentricon® installation pricing is based on foundation linear footage. Financing is available for all termite treatments.
Yes. Complimentary inspections are available throughout the DFW metro, including Plano, Frisco, McKinney, Arlington, Fort Worth, and all Dallas County communities.
DFW's primary swarm season runs March through May, triggered by warm days following spring storms. A secondary swarm sometimes occurs in September–October. Swarmers inside your home mean the colony is already established in or beneath the structure.
Older neighborhoods with pier-and-beam foundations face the highest risk — Lakewood, M Streets, Oak Lawn, Bishop Arts, and Kessler Park. Homes near the Trinity River floodplain and White Rock Creek also see elevated pressure. East Dallas renovation sites are at risk when existing barriers are disturbed.
Termite damage isn't covered by homeowner insurance. A free inspection takes less than an hour and could save you thousands. Romex has protected DFW homes since 2016.
