Why Millbrae

Why this happens here, not just "everywhere."

Cockroaches need three things to establish a colony: food, water, and warmth. Millbrae's housing stock gives them exactly that. A mix of older wood-frame Victorian and mid-century homes and newer high-density construction, most without air conditioning given the mild climate. Combined with Millbrae's climate — a temperate climate with minimal seasonal temperature swing, though fog and microclimates vary sharply by neighborhood — indoor cockroach pressure rarely lets up on its own.

We start with an inspection to identify the species and the source — sanitation issue, moisture problem, or entry point. Treatment centers on gel bait placed in cracks, voids, and under appliances, not broadcast spraying, since German cockroaches in particular have developed resistance to many surface sprays. A follow-up visit confirms the bait is working and the population is dropping.

Questions Answered

Cockroach Control FAQ — Millbrae.

How much does cockroach control cost in Millbrae?

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 Millbrae customers see a sharp drop in sightings within the first week, with a follow-up visit to confirm the infestation is fully cleared.
