Pest Control in Oregon

Oregon pest pressure, metro by metro

Oregon does not have one pest problem — it has one per metro, shaped by local weather:

• long wet winters and heavy moisture that drive ants, rodents and decay pests toward structures (Portland)
• long wet winters and heavy moisture that drive ants, rodents and decay pests toward structures (Salem)
• long wet winters and heavy moisture that drive ants, rodents and decay pests toward structures (Eugene)
• long wet winters and heavy moisture that drive ants, rodents and decay pests toward structures (Bend)

Across the state we cover 12 counties within these metro areas. Browse the metro pages below, or see the Oregon county index for county-level coverage.

Oregon coverage in numbers

Add the state up and coverage looks like this: about 3,857,851 people across 5 metro areas, 70 named communities, 224 ZIP codes and 12 counties — with Portland, the largest metro, carrying roughly 66% of the covered population. Annual average temperatures span from about 49°F around Bend to 56°F around Medford, a spread that moves first-frost dates, termite pressure and tick seasons from one end of Oregon to the other.

Read Oregon through its largest metro: Portland homes have a median build year of 1983, with roughly 46% of the stock built before 1980 and 62% owner-occupied. Age like that means settled gaps at foundations, mature landscaping against walls, and crawlspaces that have hosted decades of seasons — the conditions the metro pest guides on this page are written around.
