Rats & mice
Rats and mice look for garages, crawl spaces and older foundations near the river.

Ants trail into kitchens in spring, and carpenter ants work into damp wood.
Ants guide →Spiders
Webs fill eaves and porches in summer, and house spiders come in for the fall.
Spiders guide →Wasps & yellow jackets
Yellow jackets nest in lawns and wall voids in late summer.

Five mountains and a mile of river
The City of Columbia City says it sits on Highway 30, 2 miles north of St. Helens, where the Columbia is nearly a mile wide, with five peaks in view from Mount St. Helens to Mount Jefferson. The Oregon Blue Book lists the city as incorporated on June 7, 1926, and the city’s history page says the Caples House was built in 1870 by Dr. Charles Caples and is open to the public.
Rodents lead the list here. In Interstate Pest Management records for new customers with Columbia County, Oregon billing addresses over the last five years, rats and mice were on 39% of first visits, the most of any pest, compared with 33% across our whole Kelso service area. Boxelder bugs were on 11%.
When to expect it
Rodent calls come in all year, with a bump at the end of summer. In Interstate Pest Management records for new Columbia County, Oregon customers over the last five years, August brought 16% of the year’s new rat and mouse calls, the most of any month.
Share of new first-time calls by month. Source: Interstate Pest Management service records, first appointments of new customers with Columbia County, Oregon billing addresses over the last five years. Each row sums to about 100%.
Older and riverfront homes often have gaps at the foundation vents and where pipes come through. We control the rodents inside first, then quote sealing for the openings we find, with a 1-year warranty on exclusion materials.

“Technician (Camrin) did an great job with assessing our current mouse problem. Appreciate the in depth checking and did so with integrity.”
“I haven’t had problems with pests for at least 6 months due to Jeremy’s careful spraying and re-stocking of food in rat traps.”
Columbia City pest control questions
Still have a question about your Columbia City home? Call our Kelso office, Monday to Friday from 8am to 5pm.
Do you serve Columbia City from Washington?
Yes. Our Kelso office serves Columbia City, St. Helens and Deer Island, and we are licensed by the Oregon Department of Agriculture. Call 360-515-3882 and we will confirm your address.
How do mice get into the house?
Through gaps at foundation vents, garage doors, and the spots where pipes and wires come in. Your technician finds the openings during the inspection and quotes sealing them.
Do boxelder bugs breed inside?
No. They spend the winter in walls and attics and come back out in March. Sealing gaps on the sunny side of the house before October keeps most of them out.
