Pest pressure in Washington
Washington's climate is oceanic in the west, semi-arid in the east. Western Washington's wet climate drives heavy carpenter ant, rodent and slug pressure; eastern Washington sees more wasp and ant activity. That climate profile is what drives the specific pest pressure WA homeowners deal with — and it's the reason pest control programs in Washington look different than they do in colder northern states.
The biggest pest issues in Washington
Carpenter ants
Carpenter ants are the #1 wood-destroying organism in Washington — the wet western climate creates ideal conditions in old framing.
Norway rats and roof rats
Seattle and Tacoma have well-documented urban rat pressure; roof rats are common in coastal communities.
Yellowjackets and bald-faced hornets
Wasp colonies build aggressively through hot dry summers, especially east of the Cascades.
