Why Theriot

Why this happens here, not just "everywhere."

Cockroaches need three things to establish a colony: food, water, and warmth. Theriot's housing stock gives them exactly that. Elevated and pier-built homes dominate this bayou landscape, a direct response to the area's chronic flood exposure. Combined with Theriot's climate — a hot, extremely humid subtropical climate shaped by surrounding wetlands, marsh, and the Gulf of Mexico — indoor cockroach pressure rarely lets up on its own.

Because sanitation and moisture are almost always part of the problem, our process pairs targeted gel-bait treatment with a review of what's drawing roaches in — a leak, exposed food storage, cluttered voids. Broadcast sprays just scatter a colony; bait placed at the harborage site eliminates it. A follow-up visit confirms results.

Questions Answered

Cockroach Control FAQ — Theriot.

How much does cockroach control cost in Theriot?

Cost depends on the severity of the infestation and property size. A single-visit treatment for a light problem costs less than an ongoing plan for a heavier or recurring infestation. We provide a written quote after inspection, before any treatment starts.

Why do store-bought sprays and foggers not work?

German cockroaches in particular have developed resistance to many over-the-counter sprays, and foggers rarely reach the tight cracks and voids where roaches actually live. Gel bait placed directly at the harborage site is far more effective.

How long until the cockroaches are gone?

Gel bait works over one to two weeks as roaches feed and carry it back to the colony. Most Theriot customers see a sharp drop in sightings within the first week, with a follow-up visit to confirm the infestation is fully cleared.
