The Billings metro spreads across several counties, and Yellowstone County — about 2,633 square miles of Montana — carries its full share of the region's pest pressure.
What shapes pest pressure in Yellowstone County is the same force that shapes it across the metro: arid heat, cold nights and pests that shelter in the same walls people do. Expect black widow spiders and house mice to lead the call log, with wasps and yellowjackets close behind.
On the map, Yellowstone County is 2,633 square miles of Montana — the 23rd largest county in the state by land area on Census figures — with its centre near 45.94° N, 108.28° W. The Billings metro counts 3 counties, and providers serve this one from that metro under Montana licensing.
The numbers that frame Yellowstone County: 2,633 square miles, about 41% of the metro's county land, centred roughly 38 miles northeast of Billings. 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.

| Rank by area in state | 23rd of 56 counties |
| Rank by area in metro | 1st of 3 counties |

These are Yellowstone County's own numbers, not the metro's: land, rank and position from Census data. Yellowstone County sits 1st of 3 in its metro by land area, roughly 38 miles northeast of Billings — the coordinates its pest calendar is read from.
Within the same metro, Stillwater County (1,797 sq mi) lies about 57 miles to the west; Carbon County (2,048 sq mi) lies about 61 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 Idaho Falls, ID metro centre is about 257 miles to the southwest; the Logan, UT metro centre is about 326 miles to the southwest; the Rapid City, SD metro centre is about 287 miles to the southeast. 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 Yellowstone County's edge can sit closer to a neighbouring metro's crews than to its own.
The metro guides below are how Yellowstone County is served: each one is built from its metro's own climate record and housing stock.
