How the score is calculated.
Each business receives the same calculation. The rating, volume and recency components follow our electrician formula, then normalize their 70 available points to 100. License history and bond/insurance points are not used here. The original Oregon electrician comparison uses additional eligibility and license components, so its score is not directly comparable to this review-data score.
Rating · 35 points: with n ratings and average r, adjusted rating a = (n × r + 10 × 4.0) ÷ (n + 10). Points = 35 × clamp((a − 3.5) ÷ 1.5, 0, 1). With zero ratings, award zero.
Volume · 25 points: 25 × min(1, log10(1 + n) ÷ log10(501)).
Recency · 10 points: newest review within 30 days: 10; 90 days: 8; 180 days: 5; 365 days: 2; older or no ratings: 0.
Final score: 100 × (rating + volume + recency points) ÷ 70. Display one decimal; sort by the unrounded value. Ties use more Google ratings, then the lower numeric Google listing ID.
A missing review-date retrieval excludes a rated listing until resolved; it does not become a zero. No ratings earns zero. Credential matching is separate context and does not affect this score. No score or rank is changed by hand. This is a public-review-data comparison, not a workmanship or safety assessment.

Frequently asked questions
How were these Portland pest control companies ranked?
The 53 records use the published rating, review-volume and review-recency formula. The page states the credential checks completed for this trade. A review-data score is not a service-quality test.
Does a place on this list confirm current availability or coverage?
No. These are dated public records. Confirm service to your street address, the exact work, current license status and availability directly with the business.
Can a company pay for a higher rank?
No. Nobody pays to change a score or numbered position. Any separate promotional feature is disclosed and excluded from the scored comparison.

Each profile links to the original listing and any matched official record. Review text and reviewer details are not collected. Newest review dates and individual fact dates are shown in profiles. Other trade credentials and complaint histories have not been checked. A missing match does not establish a problem with a business.
