Providers plan their work county by county, and Chester County — 751 square miles inside the Philadelphia–Camden–Wilmington metro — is planned around the same weather and housing forces as the rest of the metro, felt at this county's own addresses.
Ask what drives pest calls in Chester County and the answer starts with the metro's climate — humid summers and cold winters that swing pressure between termites, ticks and overwintering invaders — and ends at the specific roof lines, crawlspaces and yards where subterranean termites, ticks and carpenter ants find their openings.
