Marion County covers about 396 square miles of Indiana and sits inside the Indianapolis–Carmel–Greenwood metro area, which means its pest pressure is the metro's pressure — read through Marion County's own landscape of homes, lots and green edges.
Marion 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.
The county's vital statistics: 396 square miles (the 47th largest of 92 in Indiana), centred at 39.78° N, 86.14° W, and one of the 11 counties composing the Indianapolis–Carmel–Greenwood metro. Pest work here is done by metro-based providers under Indiana rules.
There is a useful way to locate Marion County in the metro's pest geography: about 1 miles west of Indianapolis, holding roughly 10% of the metro counties' combined land area. A mid-sized county for this metro. The consequence shows up in the work itself — properties here draw their pest pressure from both directions, the metro's and the countryside's, and a provider who treats Marion County like the urban core, or like open country, will misjudge half the addresses in it.

Within the same metro, Boone County (423 sq mi) lies about 26 miles to the northwest; Brown County (312 sq mi) lies about 41 miles to the south; Hamilton County (394 sq mi) lies about 20 miles to the north; Hancock County (306 sq mi) lies about 19 miles to the east; Hendricks County (407 sq mi) lies about 20 miles to the west; Johnson County (320 sq mi) lies about 20 miles to the south; Madison County (452 sq mi) lies about 34 miles to the northeast; Morgan County (404 sq mi) lies about 27 miles to the southwest — and each is covered on its own county page, because a shared metro does not mean a shared pest picture.
The Bloomington, IN metro centre is about 48 miles to the southwest; the Lafayette, IN metro centre is about 68 miles to the northwest; the Terre Haute, IN metro centre is about 69 miles to the west. 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 Marion County's edge can sit closer to a neighbouring metro's crews than to its own.
