Fairfield County covers about 504 square miles of Ohio and sits inside the Columbus metro area, which means its pest pressure is the metro's pressure — read through Fairfield County's own landscape of homes, lots and green edges.
Fairfield 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: 504 square miles (the 23rd largest of 88 in Ohio), centred at 39.75° N, 82.63° W, and one of the 10 counties composing the Columbus metro. Pest work here is done by metro-based providers under Ohio rules.
Geography puts Fairfield County about 19 miles southeast of Columbus, and that position inside the metro matters more than it might seem. At 11% of the metro's total county land area, Fairfield 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 Fairfield County the same species behaves differently at the two ends of that spectrum.

These are Fairfield County's own numbers, not the metro's: land, rank and position from Census data. Fairfield County sits 3rd of 10 in its metro by land area, roughly 19 miles southeast of Columbus — the coordinates its pest calendar is read from.
Within the same metro, Union County (432 sq mi) lies about 54 miles to the northwest; Delaware County (443 sq mi) lies about 42 miles to the northwest; Franklin County (532 sq mi) lies about 25 miles to the northwest; Hocking County (421 sq mi) lies about 19 miles to the southeast; Licking County (682 sq mi) lies about 25 miles to the north; Madison County (467 sq mi) lies about 42 miles to the west; Morrow County (406 sq mi) lies about 54 miles to the north; Perry County (408 sq mi) lies about 21 miles to the east — every one of them profiled on its own page here — the metro is shared, but the reading is county by county.
The Dayton, OH metro centre is about 80 miles to the west; the Canton, OH metro centre is about 99 miles to the northeast; the Cincinnati, OH metro centre is about 114 miles to the southwest. 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 Fairfield County's edge can sit closer to a neighbouring metro's crews than to its own.
