Providers plan their work county by county, and Winnebago County — 513 square miles inside the Rockford metro — is planned around the same weather and housing forces as the rest of the metro, felt at this county's own addresses.
In Winnebago County the pattern is set overhead and underfoot: hot humid summers and deep-freeze winters that push pests indoors in waves above, and housing that gives those pests their harbourage below. carpenter ants and overwintering pests are where the two meet most often.
