Why Am I Seeing Roaches in a Clean House?

Seeing roaches in a clean home is frustrating, but it doesn't mean you're doing anything wrong. Roaches come inside looking for water, warmth, and shelter, not just food crumbs, and in Arizona they often come up from sewers and drains or in from outside, regardless of how spotless your kitchen is.

Why clean homes still get roaches

• They come for water. Roaches need moisture more than food. Drains, sinks, and bathrooms draw them in even when there's no food out.
• They come up from sewers. American roaches (the big ones) live in sewers and drains and travel up through plumbing into clean homes.
• They hitchhike. Roaches arrive in grocery bags, boxes, deliveries, and secondhand items.
• They come in from outside. During heat or after rain, roaches move indoors through gaps and door thresholds.
• Neighbors and shared walls. In attached homes, roaches travel between units no matter how clean yours is.

The difference between species matters

American roaches usually come from drains and outside and tend to be occasional invaders. German roaches are smaller, breed indoors fast, and a few can become an infestation, so seeing small roaches or egg cases is worth acting on quickly.

How to get them out

Sealing entry points, addressing drains and moisture, and targeted treatment of where they travel and harbor is what clears them, cleaning alone won't, since the source is often outside or in the plumbing.

FAQ

Are baby roaches a bad sign?

Yes, small roaches, especially German roaches, mean they're breeding indoors, which can escalate quickly. It's worth treating promptly.

Do roaches come up through drains?

American roaches commonly do. Keeping drains covered and P-traps full helps, alongside treatment and sealing.
