Sentinel GuardCarpenter Ant Control Tailored to Cedar Mill Homes
Cedar Mill's blend of mature Douglas firs, shaded ravines, and older homes near Cornell Road creates ideal conditions for carpenter ants. Colonies often start in decayed tree stumps or moist fence posts on the edge of the property, then send workers indoors through weep holes, foundation cracks, and overhanging branches that touch the roof. Once inside, they hollow out wall voids and attic framing — and because they forage mostly at night, many homeowners don't realize how advanced an infestation is until sawdust-like frass appears around baseboards or window sills.
We treat homes throughout the Cedar Mill area, from the neighborhoods around Cedar Mill Park and Sunset High School to the ridgetop properties off Saltzman and Leahy Roads. Our technicians are familiar with the damp crawl spaces, cedar siding, and expansive decks common to this area — all prime carpenter ant territory. Whether you've spotted a few large black ants in the kitchen or you're finding frass in the garage, we'll locate the source and clear the colony before it compromises your home's structure.
If you've spotted large black ants trailing along your foundation or spotted piles of sawdust-like frass near baseboards, you may have carpenter ants. Unlike termites, these wood-destroying ants don't eat wood — they tunnel through it, quietly hollowing out the framing, decks, and siding that keep your Cedar Mill home solid.
Cedar Mill's wooded lots, damp Northwest winters, and abundance of mature fir and cedar trees make it prime carpenter ant habitat. Our licensed technicians specialize in finding and eliminating colonies at the source, protecting your home from costly structural damage.

Our Carpenter Ant Treatment Process
- Full inspection We inspect your home inside and out, checking attics, crawl spaces, moisture-prone areas, and nearby trees or wood piles to locate nests and identify entry points.
- Colony identification We determine whether the colony is nesting in your home or traveling from a satellite nest outside, and map the trails carpenter ants use between food and nest sites.
- Targeted treatment We apply targeted treatments to nests and foraging pathways, using products that eliminate the queen and colony — not just the ants you can see.
- Exclusion & prevention We seal entry points and recommend simple fixes like trimming vegetation back from the house and addressing moisture issues that attract carpenter ants to Cedar Mill homes.
- Follow-up & warranty We return to confirm the colony is gone and monitor activity, keeping your home protected through the seasons when carpenter ants are most active.
