Katy is covered by 33 licensed roach-control operators, spread across the tri-county corner of Harris, Fort Bend, and Waller. Most of Katy is newer slab-on-grade brick homes on flat former rice prairie, and that flatness is the issue: the clay soil drains poorly, so flowerbeds and foundation lines stay damp long after a Gulf downpour. Outdoor American and smoky-brown "tree roaches" ride that moisture — after big storms they come up from storm drains and soaked beds and appear in garages overnight. New construction doesn't stop German cockroaches either; they arrive with cardboard and groceries and settle into brand-new kitchens.
Roach extermination near Katy typically runs $100–$400 for a one-time treatment by national cost guides, with multi-visit German roach clean-outs at $300–$600 — we are collecting exact Houston-area quotes by phone.

4.9★ (4557 reviews) TPCL #566236 Brittmoore - Tanner, Houston, TX ~16 mi
Bulwark's service tags explicitly call out roach control, with home-treatment and exterior-spraying capabilities targeting both German cockroaches sheltering indoors and the American roaches migrating in from outside.

4.8★ (7849 reviews) TPCL #566614 Houston, TX ~19 mi
German cockroach control often demands multiple visits to catch successive generations; Berrett's flexible scheduling and rescheduling options make follow-up treatments straightforward. The crew's thorough inspections and informative approach explain which interior zones—kitchen cracks, bathroom voids, appliance backs—harbor populations and why Houston's year-round humidity sustains relentless pressure.
4.6★ (9941 reviews) TPCL #566503 Fairbanks / Northwest Crossing, Houston, TX ~19 mi
Aptive Pest Control's thoroughness in exterior work shows through outside spraying around typical entry zones—foundation cracks, weep holes, garage seals—where Houston's American and smoky-brown roaches establish outdoor populations before filtering indoors.
