Providers plan their work county by county, and Callaway County — 835 square miles inside the Jefferson City metro — is planned around the same weather and housing forces as the rest of the metro, felt at this county's own addresses.
Callaway 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.
