The St. Louis metro spreads across several counties, and Warren County — about 429 square miles of Missouri — carries its full share of the region's pest pressure.
The county's homes sit in midwest country, where hot humid summers and deep-freeze winters that push pests indoors in waves. The pests that follow from that — carpenter ants, overwintering pests and house mice above all — are the ones local providers spend their year on in Warren County.
The county's vital statistics: 429 square miles (the 101st largest of 115 in Missouri), centred at 38.76° N, 91.16° W, and one of the 15 counties composing the St. Louis metro. Pest work here is done by metro-based providers under Missouri rules.
Geography puts Warren County about 45 miles west of St. Louis, and that position inside the metro matters more than it might seem.

Providers read the address before they read the pest, because in Warren County the same species behaves differently at the two ends of that spectrum.
