Green County does not have a separate pest problem from the Madison metro — it has the local edition of it, printed across 584 square miles of Wisconsin.
Green 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: 584 square miles (the 50th largest of 72 in Wisconsin), centred at 42.68° N, 89.61° W, and one of the 4 counties composing the Madison metro. Pest work here is done by metro-based providers under Wisconsin rules.
Green County sits roughly 26 miles south of Madison. Its 584 square miles make up about 18% of the land in the metro's county footprint, which places it a mid-sized county for this metro. For pest control, position is practical information: routes, response times and even the dominant pest mix shift across a metro this size, and Green County's slot in it — its distance from the core, its share of the metro's land, its own balance of dense streets and open ground — is the context every local inspection starts from.
