Lake Oswego's tree-lined, lake-adjacent neighborhoods are beautiful to live in and, unfortunately, exactly the kind of environment carpenter ants and moisture pests prefer.

Common pests we treat in Lake Oswego

Carpenter ants are the top concern for many Lake Oswego properties given the mature tree cover and proximity to the lake, with spiders and seasonal wasp activity close behind.

Our process

Every visit starts with a full inspection — identifying entry points, moisture issues, and current activity — before we recommend anything. From there, we favor non-chemical and reduced-toxicity treatments wherever they'll get the job done, back that up with physical exclusion (sealing gaps, screens, door sweeps), and build an ongoing prevention plan rather than treating pest control as a one-time fix. We handle residential, commercial, and crawlspace restoration work.

Why Lake Oswego homeowners choose PestLock

Older, well-established Lake Oswego properties often have more mature landscaping and wood contact points than newer builds elsewhere in the metro — our inspection is built around finding those specific risk areas. We've served the Portland–Vancouver metro for over 20 years.

Service area

We serve Downtown Lake Oswego, First Addition, Mountain Park, and the surrounding Oswego Lake area. If you're just outside these boundaries, reach out — we likely still cover your address.
