Jersey County is one of the counties that make up the St. Louis metro. Across its roughly 370 square miles, the pest story is the regional story told at county scale.
Jersey 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.
Jersey County — 370 square miles, centre near 39.08° N, 90.36° W, and the 81st largest of the state's 102 counties by land — belongs to the St. Louis metro alongside 14 other counties. Local providers cover it from that metro, licensed under Illinois rules.
There is a useful way to locate Jersey County in the metro's pest geography: about 23 miles north of St. Louis, holding roughly 5% of the metro counties' combined land area. A mid-sized county for this metro. The consequence shows up in the work itself — properties here draw their pest pressure from both directions, the metro's and the countryside's, and a provider who treats Jersey County like the urban core, or like open country, will misjudge half the addresses in it.
