Sonoma County does not have a separate pest problem from the Santa Rosa–Petaluma metro — it has the local edition of it, printed across 1,575 square miles of California.
Ask what drives pest calls in Sonoma County and the answer starts with the metro's climate — dry summers, mild wet winters and year-round moderate temperatures pests can work with — and ends at the specific roof lines, crawlspaces and yards where Argentine ants, drywood termites and roof rats find their openings.
Sonoma County covers 1,575 square miles of land — the 29th largest of 58 counties in California by land area, on US Census figures — centred near 38.53° N, 122.93° W. It is one of 1 counties that make up the Santa Rosa–Petaluma metro area, and pest services here are delivered by providers based in that metro, working to California licensing rules.
Geography puts Sonoma County about 0 miles southwest of Santa Rosa, and that position inside the metro matters more than it might seem. At 100% of the metro's total county land area, Sonoma County is a mid-sized county for this metro — and pest work here follows the settlement pattern: the closer a property sits to the metro's wooded and watered edges, the more its pressure resembles the countryside's; the closer to the core, the more it resembles the city's. Providers read the address before they read the pest, because in Sonoma County the same species behaves differently at the two ends of that spectrum.

The Vallejo, CA metro centre is about 56 miles to the east; the San Francisco, CA metro centre is about 61 miles to the southeast; the Yuba City, CA metro centre is about 87 miles to the northeast.
