Surrey — 200,000 sqft industrial warehouse rodent IPM, audit-ready documentation

A 200,000 sqft Surrey distribution warehouse with three connected buildings needed SQF-audit-ready rodent management. Structured IPM with 180-point monitor grid, monthly reporting, and exclusion milestones produced a zero-finding audit across two consecutive years.

Section 1

The situation

Warehouse operator faced annual SQF (Safe Quality Food) audit with rodent management as a core pillar. Their prior pest contractor had been passing audits but providing limited documentation — audit findings in the preceding two years had included incomplete monitor records and inconsistent IPM reporting. A single finding can delay SQF certification by up to 60 days. The warehouse handled food-grade and pharmaceutical distribution; certification delay would mean loss of major contracts. Six weeks until the next audit.

Section 2

The assessment

Full multi-building survey over three days. Findings: 23 identified exterior entry points across loading-dock bays, truck-seal gaps, and utility penetrations. Interior monitor grid needed re-densification (existing grid at 140 stations; SQF best practice for a facility this size is 180+). Prior contractor's documentation was verbal-summary format, not SQF-audit-ready. We proposed a 6-week structured overhaul: exclusion sealing, monitor grid expansion, and SQF-grade documentation from day one.

Section 3

The intervention

Week 1–2: exterior envelope exclusion — galvanized mesh on loading-dock door gaps, refitted truck seals, sealed utility penetrations. Week 3–4: monitor grid expansion to 180 stations with unique ID numbering and scannable barcodes for mobile check-in. Week 5: staff training on pest-awareness reporting and sighting protocols. Week 6: first month's monitoring cycle complete with full SQF-format documentation including station-by-station records, activity interpretation, and corrective action log. Ongoing: monthly service with same-week documentation delivery to Quality team, SQF-ready at any inspection window.

Section 4

The outcome

SQF audit passed at week 6 with zero pest-management findings. Subsequent year's SQF audit also passed with zero findings. Rodent monitor activity declined approximately 78% over 12 months post-exclusion work — the underlying population was materially reduced, not just managed. Warehouse operator moved to a 3-year IPM contract at contract renewal. Documentation format we established has since been adopted as the regional SQF standard for their parent company's other facilities.

Section 5

Why the prior contract was failing audits

The prior contractor was doing quarterly service and replacing bait in stations — which addresses current population without addressing entry points, and without producing audit-grade documentation. SQF auditors require station-by-station records, activity interpretation, and corrective-action logs. Facilities that treat pest management as ongoing compliance rather than discrete service calls pass audits consistently; facilities that treat it as a line-item vendor relationship fail audits regularly. The fix is structural: exclusion + documentation + quality-team integration.

Customer outcome

Our SQF auditor specifically noted the documentation standard — said it was the best she'd seen at any Lower Mainland warehouse. We went from hoping to pass each year to treating pest management as a genuine asset. The Wild Pest doesn't just service pests, they service the audit.
