Start a pest map of the Chicago–Naperville–Elgin metro and Lake County is one of its pieces: 444 square miles where the metro's climate lands on this county's own mix of subdivisions, older streets and open ground.
Lake 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.
Lake County — 444 square miles, centre near 42.19° N, 87.81° W, and the 61st largest of the state's 102 counties by land — belongs to the Chicago–Naperville–Elgin metro alongside 12 other counties. Local providers cover it from that metro, licensed under Illinois rules.
From Chicago, Lake County lies about 38 miles to the north. Counties are not equal shares of a metro: at 444 square miles, Lake County accounts for around 6% of the total county land in this one, and it is a mid-sized county for this metro. 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 Lake County's blend of the two is its own.

| Land area | 444 sq mi |
|---|---|
| Rank by area in state | 61st of 102 counties |
| Rank by area in metro | 8th of 13 counties |
| Share of metro land | 6% |
| County centre | 42.19° N, 87.81° W |
| Distance to Chicago | about 38 miles (north) |
| Counties in metro | 13 |
These are Lake County's own numbers, not the metro's: land, rank and position from Census data. Lake County sits 8th of 13 in its metro by land area, roughly 38 miles north of Chicago — the coordinates its pest calendar is read from.
Within the same metro, Kane County (519 sq mi) lies about 36 miles to the southwest; Kendall County (320 sq mi) lies about 52 miles to the southwest; Lake County (499 sq mi) lies about 54 miles to the southeast; McHenry County (603 sq mi) lies about 34 miles to the west; Newton County (402 sq mi) lies about 87 miles to the south; Porter County (418 sq mi) lies about 60 miles to the southeast; Will County (836 sq mi) lies about 52 miles to the south; Cook County (945 sq mi) lies about 22 miles to the south — every one of them profiled on its own page here — the metro is shared, but the reading is county by county.
The Rockford, IL metro centre is about 61 miles to the west; the Bloomington, IL metro centre is about 129 miles to the southwest; the Champaign, IL metro centre is about 137 miles to the south. 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 Lake County's edge can sit closer to a neighbouring metro's crews than to its own.
