Boxelder Bug Control in Clayton, California

Why Clayton homes get boxelder bugs

The sandy loam and clay that surrounds Clayton is the starting point. It retains moisture at the foundation line, which is what boxelder bugs need to thrive. The coastlines, valleys, and mountain ranges adds harborage, and the Mediterranean to desert climate keeps the activity going through most of the year. Homes on slab foundations, with crawl spaces, or near the the Pacific Ocean, the Sacramento River, and Sierra-fed rivers see the heaviest pressure. The older neighborhoods and the newer subdivisions each bring their own pest profile.

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 Clayton?

An exterior treatment runs $150 to $350 in Clayton, 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 Clayton?

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.
