Cockroach Control

Cockroaches in Arizona almost always mean one of two very different problems. American roaches — often called water bugs — come up through drains, sewer cleanouts, and block wall voids, drawn by moisture more than food. German roaches are the opposite: small, fast-breeding, and almost entirely indoors, usually arriving in a box or bag rather than walking in from outside. Treating them the same way rarely works, which is why identifying which one you have comes first.

Two roaches, two treatments

An American roach problem is really a moisture and access problem — treatment focuses on the drains, cleanouts, and voids they’re using to get in, not the kitchen. A German roach problem is a harborage and food-source problem, and it responds best to gel bait placed directly where they hide, not a broad interior spray (which can actually disperse a colony into neighboring rooms or units and make the job harder).

Why German roach infestations spread between units

In condos, apartments, and duplexes, German roaches move through shared wall voids and plumbing chases, which is why a unit that treats on its own can still see activity return from next door. Multi-unit properties usually need a coordinated approach rather than a single-unit spot treatment — see commercial pest control for multi-unit and property-management service.
