Mercer County does not have a separate pest problem from the Davenport–Moline–Rock Island metro — it has the local edition of it, printed across 561 square miles of Illinois.
In Mercer County the pattern is set overhead and underfoot: hot humid summers and deep-freeze winters that push pests indoors in waves above, and housing that gives those pests their harbourage below. carpenter ants and overwintering pests are where the two meet most often.
Mercer County covers 561 square miles of land — the 45th largest of 102 counties in Illinois by land area, on US Census figures — centred near 41.21° N, 90.74° 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.
Geography puts Mercer County about 19 miles southwest of Davenport, and that position inside the metro matters more than it might seem. At 25% of the metro's total county land area, Mercer County is a mid-sized county for this metro — and pest work here follows the settlement pattern: the closer a property sits to the metro's wooded and watered edges, the more its pressure resembles the countryside's; the closer to the core, the more it resembles the city's. Providers read the address before they read the pest, because in Mercer County the same species behaves differently at the two ends of that spectrum.

These are Mercer County's own numbers, not the metro's: land, rank and position from Census data. Mercer County sits 2nd of 4 in its metro by land area, roughly 19 miles southwest of Davenport — the coordinates its pest calendar is read from.
Within the same metro, Scott County (458 sq mi) lies about 31 miles to the north; Henry County (823 sq mi) lies about 33 miles to the east; Rock Island County (427 sq mi) lies about 20 miles to the northeast — and each is covered on its own county page, because a shared metro does not mean a shared pest picture.
The Iowa City, IA metro centre is about 52 miles to the northwest; the Cedar Rapids, IA metro centre is about 76 miles to the northwest; the Waterloo, IA metro centre is about 129 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 Mercer County's edge can sit closer to a neighbouring metro's crews than to its own.
