Same content, different weights

Section 1 vs 2 Picker

  1. Visible active infestation found→Section 1 finding(Active evidence or damage)
  2. Conducive condition, no evidence→Section 2 finding(Likely future risk)
  3. Area inspector could not reach→Further-inspection item(Neither Section 1 nor 2)
  4. Roof was not inspected→Boldface roof statement(Recommend licensed roofer)

WDO Identification

Subterranean Termites
Need soil; build mud tubes
Drywood Termites
No soil; six-sided pellets
Dampwood Termites
Need high-moisture decayed wood
Wood-Decay Fungus
Moisture-driven; no insect
Wood-Boring Beetles
Round exit holes, powdery frass
Carpenter Ants/Bees
Tunnel to nest, not feed

License Ladder

RA -> FR -> Operator

RA: apply pesticide onlyFR: inspect and signOperator: owns the company

Section 1 vs Section 2

Section 1

  • Visible evidence
  • Active infestation
  • Resulted damage

Section 2

  • No visible evidence

Subarea Ventilation
Reduces persistent excess moisture
Building Code Rule
Repairs follow Title 24 CCR

Common Traps

Monitoring vs Bait Station

Monitoring has no pesticide ≠ Bait station contains pesticide

Report Clock Start Point

Clock starts at inspection start ≠ Not at report completion

Conducive Condition vs Defect

Conducive means likely future risk ≠ Defect means current evidence

Branch 3 vs Branch 1

Branch 3 uses insecticide repair ≠ Branch 1 uses lethal gas

Business Days vs Calendar Days

Deadlines count business days only ≠ Weekends and holidays excluded

Extermination vs Repair

Extermination means killing the pest ≠ Repair is a separate step

FR vs Operator Privilege

FR inspects and signs reports ≠ Operator also owns the company
