Rock Island County does not have a separate pest problem from the Davenport–Moline–Rock Island metro — it has the local edition of it, printed across 427 square miles of Illinois.
Rock Island County's pest calendar is the regional one with a local accent: hot humid summers and deep-freeze winters that push pests indoors in waves, and the work concentrates on carpenter ants first, overwintering pests second, and house mice never far behind.
On the map, Rock Island County is 427 square miles of Illinois — the 67th largest county in the state by land area on Census figures — with its centre near 41.47° N, 90.57° W. The Davenport–Moline–Rock Island metro counts 4 counties, and providers serve this one from that metro under Illinois licensing.
The numbers that frame Rock Island County: 427 square miles, about 19% of the metro's county land, centred roughly 5 miles northwest of Davenport. A mid-sized county for this metro. Local providers plan around exactly this kind of framing, because the distance from the core predicts which problems arrive first in spring, which linger latest in autumn, and how the county's housing — its age, its spacing, its tree cover — translates weather into pest calls.

These are Rock Island County's own numbers, not the metro's: land, rank and position from Census data. Rock Island County sits 4th of 4 in its metro by land area, roughly 5 miles northwest of Davenport — the coordinates its pest calendar is read from.
Within the same metro, Scott County (458 sq mi) lies about 12 miles to the north; Henry County (823 sq mi) lies about 24 miles to the east; Mercer County (561 sq mi) lies about 20 miles to the southwest — every one of them profiled on its own page here — the metro is shared, but the reading is county by county.
The Iowa City, IA metro centre is about 56 miles to the west; the Cedar Rapids, IA metro centre is about 68 miles to the northwest; the Waterloo, IA metro centre is about 123 miles to the northwest. Those distances are the county's real geography, and pest work respects it: providers cross metro lines on their routes every week, and an address near Rock Island County's edge can sit closer to a neighbouring metro's crews than to its own.
Coverage for Rock Island County runs through these metro guides, every one of them written from local climate and housing data rather than a template.
