Why Winlock homes get boxelder bugs

The setting around Winlock does most of the work. The volcanic loam holds the moisture the pests need, the the coast, Puget Sound, the Cascades, and the Columbia Basin offers shelter, and the Mediterranean to oceanic climate extends the active season. The homes near the the Pacific, Puget Sound, the Columbia River, and lakes and the ones on the older streets with mature trees see the heaviest pressure, and the newer construction brings its own set of conditions.

• Seal the gaps around the windows, doors, and soffits.
• Repair the screens and the weatherstripping.

Frequently Asked Questions

Q: Are boxelder bugs harmful?

No. They are a nuisance pest that does not bite or damage the structure, but the clusters and the odor are a problem when they gather in large numbers.

Q: Do you treat the trees or just the house?

We treat both. The trees are where they feed and gather, and the house is where they enter, so the treatment covers both to break the cycle.

Q: How much does boxelder bug control cost in Winlock?

An exterior treatment runs $150 to $350 in Winlock, with the tree treatment from $150 to $300. Exclusion work runs higher depending on the number of gaps.

Q: When do the boxelder bugs appear in Winlock?

They gather on the sunny walls in the fall, usually September through October, then overwinter in the gaps and the wall voids, and re-emerge on the warm days of early spring.

Q: Why do I have so many boxelder bugs?

They are drawn to the boxelder and maple trees for feeding, and to the sunny walls for warmth. The numbers build where the host trees are close to the house.
