Older homes in two river towns
The U.S. Census Bureau’s American Community Survey puts the median year built for Centralia homes at 1975 and for Chehalis homes at 1963, and 59% of Centralia homes and 69% of Chehalis homes were built before 1980, compared with 44% across Washington. Older foundations and crawl spaces stay damper and have more ways in. That is why our inspections in older neighborhoods start under the house and around the vents.
Lewis County is farm country. The USDA’s 2022 Census of Agriculture ranks it first in Washington for poultry and eggs and first for Christmas trees. Feed, barns and outbuildings draw rodents, and our Lewis County records show it: rats and mice were on 33% of first visits for new Lewis County customers over the last five years, and boxelder bugs on 14%, nearly three times the Thurston County share.
When to expect it
Rodents are a year-round call here, with a rise in fall. In Interstate Pest Management records for new customers with Lewis County billing addresses over the last five years, September brought 17% of the year’s new rodent calls and September through December brought 42%. Boxelder bug calls come in two waves, in March and again in October.
Share of new calls by month. Source: Interstate Pest Management service records, first appointments of new customers with Lewis County billing addresses over the last five years. Each row sums to about 100%.
For the shop, the barn or a stored-feed problem, the Washington State Department of Health says mice can fit through a quarter-inch gap and advises keeping feed and seed in tight containers. For a bug you can’t name, the WSU Lewis County Plant & Insect Clinic at 17 SW Cascade Ave. in Chehalis takes insect samples Monday to Thursday, 9am to 3pm.

Centralia and Chehalis pest control questions
Still have a question about your Centralia or Chehalis home? Call our Olympia office, Monday to Friday from 8am to 5pm.

Can you treat barns, shops and outbuildings?
Yes. Tell us about them when you book, and your technician will include them in the inspection.
Why are there so many boxelder bugs on my house?
They gather on sunny walls in fall looking for a place to spend the winter, then come back out in spring. Boxelder bugs were on 14% of first visits for new Lewis County customers in our records from the last five years. Sealing gaps keeps most of them out, and our plan covers treating the walls where they gather.
