TL;DR
German cockroach harborage is any tight, warm, humid void where Blattella germanica clusters and breeds, classically hinge gaps, appliance motor housings, cabinet seams, and the space behind a refrigerator. Technicians locate it with flushing agents, glue monitors, and fecal-spotting patterns, because gel baits only work when placed within inches of these refuges.
What it means
German cockroach harborage is any tight, warm, humid void where Blattella germanica clusters and breeds, classically hinge gaps, appliance motor housings, cabinet seams, and the space behind a refrigerator. Technicians locate it with flushing agents, glue monitors, and fecal-spotting patterns, because gel baits only work when placed within inches of these refuges. Reducing it through caulking cracks, fixing leaks, and decluttering does more for long-term control than spraying exposed surfaces.
