Arlington sits squarely between Dallas and Fort Worth on the geological boundary where Blackland Prairie clay meets Grand Prairie limestone — creating a dual-soil environment that supports subterranean termites year-round. As DFW's third-largest city with thousands of homes built in the 1960s–1990s expansion era, Arlington has some of the highest termite pressure in the metroplex. Romex is your locally managed, Sentricon®-certified termite team.

Arlington is DFW's third-largest city and one of its oldest suburban communities. The city's housing stock spans six decades of construction — from 1960s ranch homes near UT Arlington to 2020s builds in Viridian — creating a wide range of termite vulnerabilities. The oldest neighborhoods have long exceeded their original soil treatment lifespan, while mid-era homes (1980s–2000s) are entering the critical degradation window now.
Arlington's geology is unique in DFW: it straddles the Blackland Prairie / Grand Prairie boundary. Eastern Arlington (east of Cooper Street) sits on heavy black clay that retains moisture against foundations, creating ideal subterranean termite habitat. Western Arlington transitions to the limestone and chalky marl of the Grand Prairie formation, where termites exploit cracks, expansion joints, and moisture-trapping landscape features.
The Johnson Creek watershed running through central Arlington, Village Creek along the southern boundary, and the Trinity River bottoms to the north provide permanent moisture corridors that sustain established termite colonies year-round. Neighborhoods near these waterways — including North Arlington, Dalworthington Gardens, and areas near River Legacy Park — face consistently elevated termite pressure.
Liquid soil treatments create a chemical barrier that degrades over time. Sentricon® takes a fundamentally different approach — it targets the colony itself.
Our TDA-licensed inspector evaluates your property's foundation perimeter, identifies active mud tubes, moisture intrusion points, and wood-to-soil contacts. Sentricon® stations are installed every 10 feet around your foundation — in Arlington's clay soils, we often tighten spacing to 8 feet near high-risk areas like garden beds and AC condensate drains.
Subterranean termites forage constantly through soil. In the heavy clay around Arlington, foraging tunnels can extend 300+ feet from the colony. The Recruit HD bait contains a chitin synthesis inhibitor — termites consume it and share it through trophallaxis (mouth-to-mouth feeding), carrying the active ingredient back to the colony.
The active ingredient (noviflumuron) prevents termites from molting. Since every termite must molt to survive, the effect cascades through the colony — workers, soldiers, reproductives, and the queen are all eliminated. Colony collapse typically occurs within 60–90 days of initial bait uptake.
Stations remain in the ground permanently and are checked quarterly. If a new colony moves into the area — common in Arlington's expanding suburban developments — the stations intercept it before it reaches your home. This continuous protection is what sets Sentricon® apart from one-time liquid treatments.
Pencil-width mud tubes running vertically on your foundation or interior walls. In Arlington, these most often appear on the shaded north and east sides of homes where moisture lingers. Check behind landscaping — dense plantings against foundations are the #1 concealment factor we see in the field.
Translucent, equal-length wings shed by reproductive termites after mating flights. The primary swarm season in the Mid-Cities runs March through May, triggered by warm days following rain events. Swarmers inside your home indicate 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 — especially in older homes with original wood framing. In our experience, this is the sign most homeowners notice only after significant damage has already occurred.
Moisture from termite tunneling behind walls causes paint to bubble or peel. This is often misdiagnosed as water damage, particularly in bathrooms and kitchens where plumbing creates additional moisture that attracts foragers.
Advanced termite damage to floor joists and subfloor causes visible sagging. Doors and windows that suddenly stick may indicate structural damage beneath. We recommend immediate inspection if you notice this — by the time structural signs appear, colony activity has been underway for months.
Small piles of soil-like material near baseboards, in crawl spaces, or on windowsills can be termite "workings" — soil packed into tunnels. In the Mid-Cities's clay soils, this is sometimes mistaken for dirt kicked up by settling foundations.
Eastern subterranean termites are the dominant species across Tarrant County. Arlington sits on the Blackland Prairie–Grand Prairie geological boundary, with both clay and limestone substrates supporting termite colonies. Formosan subterranean termites have been confirmed in scattered DFW locations.
Central Arlington homes built in the 1960s–1980s with original pier-and-beam foundations face the highest risk. Properties along Johnson Creek and Village Creek see elevated moisture. North Arlington near the Trinity River floodplain is also high-pressure. Newer South Arlington developments are entering the risk window.
Arlington's primary swarming season runs March through May, triggered by warm days following spring rains. A secondary window opens September–October. Swarmers inside indicate an established colony.
