German cockroaches don't respond to retail sprays — many Austin populations have developed resistance to the active ingredients in store-bought products. Romex uses professional-grade gel baits rotated on a schedule to eliminate resistant colonies in apartments, kitchens, and commercial spaces.
Austin homeowners face two distinct cockroach challenges that require completely different treatment strategies. Understanding which species you're dealing with determines whether your problem is a seasonal nuisance or a chronic infestation.
German cockroaches (Blattella germanica) are Austin's most medically significant roach species. They live exclusively indoors — they don't come in from outside like other species. They spread through infested items (used appliances, cardboard, grocery bags, furniture), shared walls in multi-unit buildings, and deliveries. Once established, they multiply explosively: a single female produces an egg case (ootheca) every 6 weeks containing 30–40 nymphs.
The worst infestations we see in Austin are in West Campus apartments near UT, older complexes along Riverside Drive and Oltorf, and commercial kitchens across the metro. Multi-unit housing is particularly vulnerable because cockroaches travel between units through shared plumbing and electrical chases. Treating one unit without addressing the building is futile.
American cockroaches ("water bugs" or "palmetto bugs") and smoky brown cockroaches live outdoors in Austin's sewer systems, tree holes, mulch beds, and wood piles. They enter homes through plumbing traps, weep holes, under doors, and via attic vents (smoky browns are strong fliers attracted to lights). These species are a year-round nuisance across all Austin neighborhoods, particularly homes near creek corridors and those with older plumbing infrastructure.
Blattella germanica
Small (½–⅝ inch), light brown with two dark stripes behind the head. The only roach species that lives exclusively indoors. Hides in cracks near heat and moisture — behind refrigerator compressors, under sinks, inside dishwasher motors, behind stove backsplashes, and in electrical outlets.
Health impact: Cockroach allergens from droppings, shed skins, and saliva are a leading asthma trigger in children. The EPA identifies German cockroach infestations as a significant indoor air quality concern.
Romex approach: Professional gel bait applied in cracks and crevices where roaches harbor. We rotate bait active ingredients on each visit to prevent resistance buildup. No broadcast spraying — repellent sprays drive cockroaches deeper into walls and scatter the population.
Periplaneta americana
Large (1.5–2 inches), reddish-brown with a yellowish figure-eight pattern behind the head. Austin locals call them "water bugs" or "tree roaches." They live in sewer systems, storm drains, and damp outdoor environments. They enter homes through plumbing traps (especially floor drains and rarely-used toilets).
Romex approach: Exterior perimeter barrier treatment prevents entry. Interior crack-and-crevice treatment in bathrooms and kitchens. Plumbing trap inspection to identify entry routes. Regular service on an every-other-month or quarterly cadence keeps the barrier active.
Periplaneta fuliginosa
Large (1–1.5 inches), uniformly dark mahogany-brown. Strong fliers attracted to exterior lighting. Common in Austin's tree canopy, gutters, and attic spaces. They enter through gable vents, soffit gaps, and weep holes, particularly on warm evenings when exterior lights attract them.
Romex approach: Exterior light management guidance, attic vent screening, and perimeter treatment. Addressing moisture in gutters and fascia areas reduces harborage near the roofline.
Blatta orientalis
Medium (1 inch), shiny dark brown to black. Strongly associated with moisture — found in basements, crawl spaces, water meter boxes, and beneath mulch beds. Slower-moving than other species and produces a distinctive musty odor.
Romex approach: Moisture reduction and harborage elimination. Granular bait in exterior landscape beds and crack-and-crevice treatment near foundation-level entry points.
Same-day cockroach treatment available across the Austin area. Our technicians carry professional-grade gel baits and equipment for immediate treatment.
German cockroaches (indoor-only, kitchen and bathroom infestations), American cockroaches ("water bugs" from sewer systems), smoky brown cockroaches (fliers attracted to lights, enter through attic vents), and Oriental cockroaches (moisture-loving, basements and crawl spaces).
They reproduce explosively (300–400 offspring per female), live exclusively indoors in inaccessible crevices, and many Austin populations have developed resistance to retail spray products. Professional gel bait rotation is the most effective approach.
General pest plans covering outdoor roach species start at $129–$149 per service. German cockroach infestations require dedicated treatment programs with initial cleanout and follow-up visits — pricing varies by space size and severity.
Yes. Cockroach allergens (droppings, shed skins, saliva) are a leading asthma trigger, especially in children. German cockroach infestations significantly degrade indoor air quality. The EPA classifies cockroach allergens as a significant health concern.
American cockroaches enter through plumbing traps (floor drains, rarely-used toilets), weep holes, and under exterior doors. Smoky brown cockroaches fly to exterior lights and enter through gable vents, soffit gaps, and attic openings. Perimeter treatment and entry point sealing prevent most intrusions.
Retail sprays scatter cockroaches — they don't eliminate them. Romex uses professional gel baits and bait rotation to collapse resistant German cockroach populations, and perimeter barriers to keep outdoor species outside.
