Henry County does not have a separate pest problem from the Davenport–Moline–Rock Island metro — it has the local edition of it, printed across 823 square miles of Illinois.
Read Henry County's pest list off its geography: hot humid summers and deep-freeze winters that push pests indoors in waves, and the result is a calendar dominated by carpenter ants, overwintering pests and house mice.
Henry County covers 823 square miles of land — the 15th largest of 102 counties in Illinois by land area, on US Census figures — centred near 41.35° N, 90.13° W. It is one of 4 counties that make up the Davenport–Moline–Rock Island metro area, and pest services here are delivered by providers based in that metro, working to Illinois licensing rules.
Henry County sits roughly 21 miles east of Davenport. Its 823 square miles make up about 36% of the land in the metro's county footprint, which places it a mid-sized county for this metro. For pest control, position is practical information: routes, response times and even the dominant pest mix shift across a metro this size, and Henry County's slot in it — its distance from the core, its share of the metro's land, its own balance of dense streets and open ground — is the context every local inspection starts from.

Within the same metro, Rock Island County (427 sq mi) lies about 24 miles to the west; Scott County (458 sq mi) lies about 32 miles to the northwest; Mercer County (561 sq mi) lies about 33 miles to the west — each with its own county page in this index, because pest pressure is read county by county even when the metro is shared.
The Iowa City, IA metro centre is about 80 miles to the west; the Cedar Rapids, IA metro centre is about 91 miles to the northwest; the Waterloo, IA metro centre is about 146 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 Henry County's edge can sit closer to a neighbouring metro's crews than to its own.
