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.
Also serving nearby: Portland pest control and Happy Valley pest control.
Our 60-day guarantee
Most pest control companies guarantee their work for 30 days. We guarantee ours for 60. For one-time treatments, if pests come back within 60 days, we'll return and re-treat at no charge — no extra paperwork, no fine print working against you. For ongoing plans, covered pests are re-treated free any time between scheduled visits, for as long as your plan is active.
