Coverage in Missouri is organised county by county: 30 of them, roughly 16,994 square miles in all, tied to the St. Louis, Kansas City, Springfield, Columbia, Joplin, Jefferson City metro areas. That is the scale pest services actually run at — state licensing above, county and metro routes below — so each county below gets its own page: its pest pressure, its position in its metro, and the guides that serve it.
The counties around a metro's core are often where the pressure is most interesting — newer subdivisions built into former farmland and woodland meet established pest populations at the edge, while the urban core deals with the pests of density. Each county page reads its own position in that pattern.
By land, the covered counties run from Franklin County (923 sq mi), Bates County (837 sq mi), Callaway County (835 sq mi) down to St. Louis city at about 62 square miles. The metros anchoring coverage are St. Louis (metro population 2,814,421; 7 covered counties in Missouri); Kansas City (metro population 2,270,682; 9 covered counties in Missouri); Springfield (metro population 500,694; 5 covered counties in Missouri); Columbia (metro population 219,062; 3 covered counties in Missouri); Joplin (metro population 208,796; 2 covered counties in Missouri); Jefferson City (metro population 152,712; 4 covered counties in Missouri). 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.
The state's pest calendar is anchored by its largest metro, St. Louis: about 42 inches of precipitation a year, an average temperature near 57°F, roughly 47 days at 90°F or above and 85 days at or below freezing. Every county in this index lives inside that weather pattern, adjusted by its own distance from the metro core.
The pest signature across Missouri runs through midwest country, and the names that recur on county pages statewide are carpenter ants, overwintering pests, house mice. The largest covered county in the state is Franklin County at about 923 square miles, served through the St. Louis metro. For metro-level guides, see the Missouri state page.
The communities county residents actually name: Kansas City (about 508,233 residents), St. Louis (about 293,109 residents), Overland Park (about 197,199 residents), Springfield (about 169,432 residents), Olathe (about 143,720 residents), Columbia (about 127,200 residents) are the largest covered communities on this index; each sits inside one of the counties above, and its county page carries the local pest reading for that ground.
