Start from the county. In Indiana, 40 counties fall inside the metros PestReach USA covers — the Indianapolis, Fort Wayne, South Bend, Evansville, Lafayette, Elkhart areas among them — adding up to about 15,455 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 Allen County (657 sq mi), Jasper County (560 sq mi), Washington County (514 sq mi) down to Ohio County at about 86 square miles. The metros anchoring coverage are Indianapolis (metro population 2,205,695; 11 covered counties in Indiana); Fort Wayne (metro population 466,258; 3 covered counties in Indiana); South Bend (metro population 324,538; 1 covered county in Indiana); Evansville (metro population 273,786; 3 covered counties in Indiana); Lafayette (metro population 228,468; 4 covered counties in Indiana); Elkhart (metro population 208,774; 1 covered county in Indiana); Terre Haute (metro population 169,241; 4 covered counties in Indiana); Bloomington (metro population 165,231; 2 covered counties in Indiana). That is the arithmetic the county pages below work from: a county's size decides how spread out the addresses are, its metro decides the pest calendar, and neither number means much without the other.
Weather sets the calendar, and in Indianapolis — the state's anchor metro — it reads: 41 inches of precipitation annually, average temperatures around 54°F, 17 days reaching 90°F and 106 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 Indiana 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 Allen County at about 657 square miles, served through the Fort Wayne metro. For metro-level guides, see the Indiana state page.
