Across the bridge from Longview
The City of Rainier says Charles E. Fox founded the town in 1851 and named it for Mount Rainier, visible from the hills around the city, and that the Lewis & Clark Bridge to Longview opened on March 29, 1930. The Oregon Blue Book lists Rainier as incorporated in 1885.
Ants are the first call of the year here. In Interstate Pest Management records for new customers with Columbia County, Oregon billing addresses over the last five years, ants were on 39% of first visits, and March through June brought 55% of the year’s new ant calls. Carpenter ants were on 9%.
When to expect it
In Interstate Pest Management records for new Columbia County, Oregon customers over the last five years, March brought 17% of the year’s new ant calls, the most of any month, and calls stayed high into summer.

Odorous house ants and carpenter ants need different treatments, so we identify the ant before we treat. Baits the workers carry home reach the nest; spray on the trail does not.

Do you serve Rainier from Washington?

When is ant season in Rainier?
March through June. In Interstate Pest Management records for new Columbia County, Oregon customers over the last five years, 55% of new ant calls came in those four months.
Why do ants keep coming back after I spray?
Spray only reaches the ants you can see, and the nest keeps sending more. Baits the workers carry home reach the nest. If ants come back between scheduled visits, re-service is included in your plan.
