The St. Louis metro spreads across several counties, and Franklin County — about 923 square miles of Missouri — carries its full share of the region's pest pressure.
Ask what drives pest calls in Franklin County and the answer starts with the metro's climate — hot humid summers and deep-freeze winters that push pests indoors in waves — and ends at the specific roof lines, crawlspaces and yards where carpenter ants, overwintering pests and house mice find their openings.
The county's vital statistics: 923 square miles (the 4th largest of 115 in Missouri), centred at 38.41° N, 91.07° W, and one of the 15 counties composing the St. Louis metro. Pest work here is done by metro-based providers under Missouri rules.
There is a useful way to locate Franklin County in the metro's pest geography: about 46 miles southwest of St. Louis, holding roughly 12% of the metro counties' combined land area. One of the metro's larger counties by land. 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 Franklin County like the urban core, or like open country, will misjudge half the addresses in it.
