Frequently Asked Questions

American cockroaches originate from sewer systems and sub-grade infrastructure. They enter structures through floor drains, sewer cleanouts, and unsealed pipe penetrations in basements and mechanical rooms — not from outside the building.

Large cockroaches in basement or mechanical areas are almost always American cockroaches coming up from the sewer system. The appearance is triggered by heavy rain (which pressurizes the system), dry P-traps in floor drains, or unsealed sewer access points.

American cockroach treatment starts at the entry point — drain treatment, P-trap maintenance, and sealing pipe penetrations at slab level. Gel bait is placed in sub-grade mechanical areas. The approach is structural, not chemical-first.
