Carpenter Ant Treatment Built for Tigard Homes

Tigard's mix of mature evergreens, creek corridors along Fanno and Ash Creeks, and our wet Pacific Northwest winters makes the area prime carpenter ant territory. Homes near Cook Park, Summerlake, or the wooded slopes of Bull Mountain often deal with ants trailing in from moisture-damaged wood, fallen limbs, and tree stumps that harbor parent colonies just outside the structure.

Because carpenter ants in Tigard typically nest outdoors and forage inside, effective treatment has to reach both. We trace foraging trails back to nests in wall voids, attics, or crawlspaces, and treat exterior colonies in surrounding vegetation and landscape timbers. Whether you're seeing big black ants in your kitchen or frass piles near a window frame, we eliminate the colony—not just the ants you can see—so your home stays protected season after season.

Finding sawdust-like frass piles or large black ants trailing along your baseboards? Carpenter ants are one of the most destructive pests in Tigard, quietly excavating moisture-softened wood in walls, attics, and crawlspaces. Left untreated, they can compromise the structural wood of your home over time.

Our licensed technicians specialize in carpenter ant treatment for Tigard homes, from the older neighborhoods near downtown to newer builds on Bull Mountain. We don't just spray and go—we locate the nest, eliminate the colony, and address the moisture and entry points that drew them in.
