Start from the county. In Montana, 3 counties fall inside the metros PestReach USA covers — the Billings areas among them — adding up to about 6,478 square miles. Pest pressure is read at this level because it is the level providers work at: routes, licensing and local rules all resolve to county and metro long before they resolve to state.
Read down the list and the pattern is geographic: the counties nearest a metro core carry its density problems, the outer counties carry the edge-of-development ones — new subdivisions against farmland and woodland — and every county page on this index sets out which pattern applies there, and why.
By land, the covered counties run from Yellowstone County (2,633 sq mi), Carbon County (2,048 sq mi), Stillwater County (1,797 sq mi) down to Stillwater County at about 1,797 square miles. The metros anchoring coverage are Billings (metro population 193,603; 3 covered counties in Montana). Those numbers are the frame for everything on the county pages below: area sets how rural a county reads, the metro sets its pest calendar, and the two together set what providers actually deal with there.
Weather sets the calendar, and in Billings — the state's anchor metro — it reads: 14 inches of precipitation annually, average temperatures around 48°F, 32 days reaching 90°F and 142 freezing days. The counties below share that regime; what changes county to county is housing, land and distance from the core.
The pest signature across Montana runs through mountain desert country, and the names that recur on county pages statewide are black widow spiders, house mice, wasps and yellowjackets. The largest covered county in the state is Yellowstone County at about 2,633 square miles, served through the Billings metro. For metro-level guides, see the Montana state page.
The communities county residents actually name: Billings (about 118,321 residents), Lockwood (about 7,474 residents), Laurel (about 7,198 residents), Red Lodge (about 2,399 residents), Columbus (about 1,925 residents), Absarokee (about 998 residents) are among the largest covered places in the state, and every one of them routes through the county pages above — find the community on its county page for the local reading.
Billings — a metro of 193,603 across 3 counties, where the watch list runs black widow spiders, house mice, wasps and yellowjackets — the standing pattern where arid heat, cold nights and pests that shelter in the same walls people do.
