Union County is one of the counties that make up the Knoxville metro. Across its roughly 224 square miles, the pest story is the regional story told at county scale.
The county's homes sit in southeast country, where hot humid summers, heavy rain and mild winters in classic termite-and-ant country. The pests that follow from that — subterranean termites, mosquitoes and red imported fire ants above all — are the ones local providers spend their year on in Union County.
Union County — 224 square miles, centre near 36.28° N, 83.84° W, and the 86th largest of the state's 95 counties by land — belongs to the Knoxville metro alongside 8 other counties. Local providers cover it from that metro, licensed under Tennessee rules.
From Knoxville, Union County lies about 22 miles to the northeast. Counties are not equal shares of a metro: at 224 square miles, Union County accounts for around 6% of the total county land in this one, and it is one of the metro's more compact counties. Pest pressure tracks those proportions loosely but honestly — more open land means more wildlife and field-pest interface; tighter settlement means more of the pests of density — and Union County's blend of the two is its own.

The Johnson City, TN metro centre is about 83 miles to the east; the Chattanooga, TN metro centre is about 122 miles to the southwest; the Kingsport, TN metro centre is about 83 miles to the east. Those distances are the county's real geography, and pest work respects it: providers cross metro lines on their routes every week, and an address near Union County's edge can sit closer to a neighbouring metro's crews than to its own.
