Integrated Pest Management · Zone-Based Program

Layered Protection. Zone by Zone.

Our IPM programs start with a risk assessment of every area of your facility, then build buffer zones from the property line to the production floor. Each zone gets its own monitoring strategy, tactics and corrective actions, so pests are stopped as far from your product as possible with minimal impact on your operation.

Step One: Risk Assessment

Every Area Rated Before Any Device Goes In

We walk your facility with your team and rate each area by risk, considering:

  • Product exposure and proximity to production
  • Pest pressure history and surrounding environment
  • Construction, entry points and structural conditions
  • Sanitation conditions and material flow
  • Audit scheme and customer requirements

Those ratings define your buffer zones. Risk rises as you move inward, so tactics become more conservative and responses faster the closer an area is to product.

Pest Management in the Field

Every Device Mapped, Inspected and Logged

Our technicians inspect each zone on schedule, service every numbered device, and record findings so trends and corrective actions are visible long before an auditor arrives.

  • Mapped devices
  • Zone-based inspections
  • Trend reporting
The Four Buffer Zones

Different Zones. Different Tactics.

Each zone has its own monitoring tools, control tactics and corrective actions, chosen to protect product while keeping disruption to your operation as low as possible.

Zone 1

Property Perimeter & Grounds

Fence line, landscaping, parking, drainage and outdoor storage. The first line of defense: stop pests before they reach the building.

Risk: Low

Monitoring

  • Visual inspection of grounds, fence line and drainage
  • Burrow, runway and nesting surveys
  • Bird and wildlife activity checks
  • Secured, tamper-resistant bait stations at the property line where pressure warrants

Tactics

  • Habitat modification: weeds, debris and standing water
  • Landscaping guidance on plantings and mulch near the building
  • Outdoor storage kept off the ground and away from walls
  • Station placement adjusted to activity trends

Corrective Actions

  • Remove harborage, debris and food sources
  • Treat active burrows according to label directions
  • Add or relocate stations in active areas
  • Written recommendations for drainage, landscaping or storage fixes
Zone 2

Building Exterior

Foundation walls, roofline, docks, doors, dumpsters and exterior lighting. Where pests look for a way in.

Risk: Moderate

Monitoring

  • Secured bait stations along exterior walls and on both sides of doors
  • Inspection of doors, seals, dock levelers and wall penetrations
  • Dumpster and compactor area checks
  • Roof, ledge and canopy checks for bird activity

Tactics

  • Vegetation-free strip along the foundation
  • Exterior lighting directed away from doors to reduce insect attraction
  • Bird deterrents on ledges, signs and canopies
  • Sanitation schedule for waste and compactor areas

Corrective Actions

  • Increase service frequency at active stations
  • Seal gaps, cracks and utility penetrations
  • Repair requests for door seals, dock bumpers and weather-stripping
  • Waste-area clean-up and container or drainage fixes
Zone 3

Interior Perimeter & Support Areas

Interior walls, receiving, dry storage, warehouse, maintenance and employee areas. The last barrier before product.

Risk: Elevated

Monitoring

  • Non-toxic mechanical traps and glue monitors along walls and inside doors
  • Insect light traps near entries, not visible from outside
  • Pheromone traps for stored-product insects in ingredient and dry storage
  • Inspection of incoming materials and pallets at receiving

Tactics

  • No rodenticide baits indoors: monitoring and mechanical control only
  • Door discipline: closed doors, strip or air curtains
  • Clean, clear inspection aisles along walls
  • Spill and residue control at pallets and wall-floor junctions

Corrective Actions

  • Isolate and inspect affected materials together with QA
  • Deep clean and remove harborage at activity points
  • Add monitors and increase frequency near activity
  • Repair door sweeps and seal interior entry points; document root cause
Zone 4

Critical Product Areas

Production, packaging, exposed product and sensitive ingredients. Zero tolerance and tightly controlled.

Risk: Critical

Monitoring

  • Non-toxic monitors placed with QA approval
  • Insect light traps positioned away from exposed product and lines
  • Pheromone monitoring around sensitive ingredients
  • Equipment, void and overhead inspections during sanitation windows

Tactics

  • Non-chemical methods first
  • Any treatment only with label-approved products, scheduled with QA during non-production, with product and equipment protected
  • Prevention through sanitation: CIP and cleaning of equipment voids
  • Coordination with sanitation and maintenance teams

Corrective Actions

  • Immediate notification to QA and plant management
  • QA-led assessment of product and equipment
  • Targeted sanitation and equipment inspection
  • Heightened monitoring and a documented CAPA with root cause and sign-off
Corrective Actions by Zone

The Response Fits the Risk

The same finding calls for a different response depending on where it happens. Every corrective action is documented from finding to verification.

ZoneExample FindingImmediate ResponseFollow-Up & PreventionVerification
Zone 1Rodent burrows along the fence lineTreat active burrows per label; remove debris and harborageVegetation and drainage recommendations; adjust station placementRe-inspection at next service; activity trended
Zone 2Bait consumption at stations near the dockReplenish and increase service frequency at active stationsSeal gaps at dock levelers and doors; waste-area clean-upActivity returns to baseline over following services
Zone 3Rodent capture on an interior trap near receivingNotify facility contact; inspect area and incoming materials; sanitizeRepair door sweeps, add monitors, review door practicesFocused follow-up inspection on a schedule agreed with QA
Zone 4Insect activity near a production lineImmediate QA notification; area handled per QA directionTargeted sanitation, equipment inspection and exclusion; root-cause analysisHeightened monitoring; CAPA closed with QA sign-off
Escalation

Clear Thresholds. Clear Responses.

Everyone knows in advance what happens, who is notified and how fast.

Level 1

Routine Finding

Activity within the expected range in Zones 1 and 2.

  • Addressed during the service visit
  • Recorded on the service report
  • Included in trend analysis
Level 2

Threshold Exceeded

Activity above agreed thresholds, or any activity in Zone 3.

  • Same-day notification to your facility contact
  • Written corrective action plan
  • Increased monitoring until resolved
Level 3

Critical Finding

Any activity in Zone 4 or any potential product-contact risk.

  • Immediate notification to QA and plant management
  • QA-led product and equipment assessment
  • Documented CAPA with root cause and verification

Activity thresholds for each zone are set with your QA team during the risk assessment and reviewed as trend data builds.

A Continuous Program

Assess. Monitor. Respond. Improve.

IPM isn't a one-time setup. Trend data feeds back into the risk assessment, so the program gets sharper over time.

1

Assess

Rate every area by risk before any device goes in.

2

Zone & Map

Define buffer zones and map every numbered device.

3

Monitor

Zone-specific tools, inspected on a set frequency.

4

Respond

Corrective actions matched to the zone and the finding.

5

Trend

Activity analyzed by zone, device and pest over time.

6

Review

Program adjusted as conditions and risks change.
