Older homes and fall invaders
The U.S. Census Bureau’s American Community Survey puts the median year built for Castle Rock homes at 1971, and 71% were built before 1980, compared with 44% across Washington. Homes that age tend to have open foundation vents, worn door sweeps and gaps where old pipes and wires come through. Those are the first places we check for rats and mice, and damp crawl spaces under older floors are where moisture ants and carpenter ants turn up.
Castle Rock’s pest calendar has its own signature. In Interstate Pest Management records for new customers with Castle Rock billing addresses over the last five years, boxelder bugs were on 27% of first visits, about four times the Longview share, and wasps and yellow jackets on 16%.
When to expect it
Boxelder bugs come in two waves here. In Interstate Pest Management records for new Castle Rock customers over the last five years, March and October each brought 29% of the year’s new boxelder bug calls, as the bugs come out of their winter shelter and then look for it again.
Share of new first-time calls by month. Source: Interstate Pest Management service records, first appointments of new customers with Castle Rock billing addresses over the last five years. Each row sums to about 100%.
Sealing gaps around windows, siding, vents and the foundation before October keeps most boxelder bugs out. Our plan covers treating the sunny walls where they gather, ahead of each wave.

What our customers say
4.96 average from 8,394 Google reviews
“Interstate has been great at helping with our bug issues, I swear Castle Rock is built on an ant hill and I could not get rid of them inside our home now matter how clean I kept it. But I haven’t seen any in months now & I couldn’t be happier!”
“Interstate Pest Management was recommended to us by our neighbor. Camrin came out and was very informative, helpful and efficient. He treated our kitchen for “cement ants” including the whole perimeter of outside the house. He not only cleaned away spiderwebs from house and eaves, but sprayed the eaves as well. Camrin also took care of wasps that were nesting in vacant bird houses we had around the outside of the house. We are very happy with the care Camrin has taken.”
“Keith was great, he was efficient and answered my questions clearly. Good Job! He and Austin are the best.”

Do you serve all of Castle Rock?

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 March. Boxelder bugs were on 27% of first visits for new Castle Rock customers in our records over the last five years.
Do they breed inside the house?
No. Boxelder bugs spend the winter in walls and attics but do not breed indoors. Keeping them out is mostly about sealing the gaps they use.
