Red imported fire ants infest virtually every yard in Travis County. Carpenter ants silently hollow out structural timbers in Austin's older neighborhoods. Romex treats the colony, not just the mound — with species-specific methods backed by our satisfaction guarantee.
Austin's geography creates near-perfect conditions for multiple ant species. The city straddles the Blackland Prairie and Edwards Plateau — two ecoregions that intersect along the Balcones Escarpment, roughly following MoPac (Loop 1). East of MoPac, deep clay soils and irrigated residential lawns provide the moisture and nutrient-rich soil that fire ant queens need to establish mega-colonies. West of MoPac, rocky Hill Country terrain pushes carpenter ants into homes for moisture and nesting sites.
The Austin metro has added hundreds of thousands of new residents since 2010, and with that growth came massive land disturbance — clearing, grading, and construction that destroys existing ant colonies and forces them into yards, playgrounds, and structures. Neighborhoods like Mueller, East Austin, Pflugerville, and Hutto built on former farmland see particularly intense fire ant pressure because the colonies simply relocate into the new residential lots.
Fire ant stings send more Texans to the emergency room than any other insect. A single fire ant mound can contain 200,000–500,000 workers. When disturbed, they swarm and sting simultaneously — a coordinated chemical alarm triggers mass attack. Children, pets, and elderly residents on blood thinners are most at risk. Austin's parks department treats public spaces, but private yards require homeowner action.
Solenopsis invicta
The dominant pest ant in Austin. Fire ants build dome-shaped mounds in sunny, open areas — lawns, medians, sports fields, and playgrounds. Colonies explode after spring rains (March–May) when queens fly and establish new mounds. A single acre in Austin can have 40+ active mounds.
Romex approach: Broadcast bait application across the entire yard targets foraging workers who carry the product back to the queen. This is far more effective than individual mound treatments, which only scatter the colony. We pair this with perimeter barrier treatment at the foundation.
Camponotus spp.
Large black or bicolored ants that excavate galleries in wood for nesting. Common in Austin neighborhoods with mature trees — Hyde Park, Zilker, Tarrytown, Travis Heights. They target moist, decaying wood first, then extend into sound structural timber. Satellite colonies can be inside wall voids without any exterior sign.
Romex approach: Locate the parent colony (often in a dead tree or stump within 300 feet) and all satellite nests. Direct treatment of the colony combined with perimeter exclusion and moisture correction eliminates the infestation at the source.
Monomorium pharaonis
Tiny (1/16") yellowish ants that thrive in heated buildings. Austin's hospitals, nursing homes, restaurants, and apartment complexes near UT campus and Riverside are chronic hotspots. Colonies have multiple queens and split ("bud") when disturbed by contact sprays — making DIY treatment counterproductive.
Romex approach: Bait-only protocol. No repellent sprays near pharaoh ant trails. Slow-acting bait is carried back to all nest sites, including inaccessible wall voids and ceiling spaces. Full colony elimination takes 2–4 weeks.
Tapinoma sessile
Small dark ants that form long trailing lines from outdoor nests into kitchens and bathrooms. They emit a distinctive rotten-coconut smell when crushed. Extremely common in Austin homes of all ages, especially after rain drives colonies toward dry interior spaces.
Romex approach: Combination of exterior perimeter treatment to break trails and interior gel bait at entry points. Sealing of cable and pipe penetrations to cut off access routes. Colonies typically collapse within 1–2 weeks of baiting.
Same-day ant control service available for most Austin-area communities. Our technicians are local and know where each species thrives.
Red imported fire ants, carpenter ants, odorous house ants, and pharaoh ants are the most common species. Fire ants dominate outdoor spaces while carpenter ants target older homes with mature trees. Pharaoh ants are a persistent problem in apartments and commercial kitchens.
General pest control plans that include ant treatment start at $129–$149 per service on an every-other-month or quarterly cadence. Carpenter ant treatment may require a separate inspection and targeted interior treatment based on infestation extent.
Fire ants are active year-round in Austin due to mild winters. Peak activity occurs in spring (March–May) after rains trigger mound building, and again in fall (September–November) during pre-winter foraging. Summer heat drives colonies deeper underground during the day.
DIY mound treatments kill surface ants but rarely reach the queen, who may be 6+ feet underground. The colony relocates and rebuilds nearby. Professional broadcast bait applications treat the entire yard and are carried back to the queen for full colony collapse.
Carpenter ants produce clean, sawdust-like frass pushed out of their galleries. They don't eat wood — they excavate it. Termites consume wood and produce mud tubes on foundations. Carpenter ants are large (¼–½ inch) and black; termite workers are small, pale, and soft-bodied.
Fire ants, carpenter ants, and kitchen invaders don't go away on their own. Romex treats the colony — not just the ants you see — with a satisfaction guarantee that includes free retreatment.
