Placement Guidance
- Place boards flush to walls and behind stored materials.
- Prioritize corners (suggested 0) and dark, quiet edges.
- Add boards at each entry, loading bay, and utility penetration.
- Keep boards away from heavy foot traffic and wet zones.
- Label each board with date, location code, and inspector.
Inputs
Formula Used
1) Area and perimeter
- Area = Length × Width
- Perimeter = 2 × (Length + Width)
2) Wall boards
- Wall Boards = ceil(Perimeter ÷ Wall Spacing)
3) Interior boards
- Interior Coverage ≈ (Interior Spacing)²
- Interior Boards = ceil(Area ÷ Interior Coverage)
4) Hotspots and risk
- Entry Boards = Entry Points × 2
- Sensitive Boards = Sensitive Areas × 2
- Base Boards = Wall + Interior + Entry + Sensitive
- Risk Adjusted = ceil(Base Boards × Risk Multiplier)
- Total = Risk Adjusted + ceil(Risk Adjusted × Buffer%)

Tip: Shorter spacing improves detection but increases maintenance.
Perimeter-first coverage for active structures
Glue boards work best when aligned with travel routes. In most buildings, pests follow edges where light and airflow change. Start by placing boards along walls and behind fixed equipment. A practical field range is 2–4 m spacing on accessible walls. Tighten spacing in cluttered rooms, around pipe chases, and near slab joints, door thresholds, and service penetrations.
Interior grid for open floors and corridors
Open interiors often need a secondary grid to avoid blind spots. Use a wider spacing than walls, typically 4–8 m, and keep lanes clear for inspections. For long corridors, place boards in alternating offsets so each board covers a different sightline. Where forklifts operate, keep boards out of wheel paths, protect them from washdown, and position them beside guards or columns.
Hotspot targeting at entries and moisture sources
Entries, loading docks, and material laydown zones raise capture rates. Doubling boards at each entry point improves early detection and helps isolate the direction of movement. Moisture sources such as break areas, temporary sinks, condensate drains, and low points in vapor barriers also act as attractors. Mark each hotspot on the plan so replacement remains consistent across shifts and subcontractors.
Risk-adjusted quantity and buffer planning
Total boards should reflect both footprint and risk. A moderate-risk site typically uses a baseline wall count plus interior count, then adds entry and sensitive-area boards. Apply a multiplier for risk when food waste, standing water, or frequent deliveries are present. Include a 5–15% buffer for damaged, saturated, or relocated boards, and keep spare stock staged with the inspection kit.
Inspection cadence and documentation standards
Placement is only useful when boards are checked on a schedule. High-traffic sites may require daily checks, while stable areas can be weekly or biweekly. Label boards with location IDs, dates, and initials, and replace immediately after a positive capture. Track counts and findings in CSV or PDF reports to support audits, corrective actions, and trend analysis over time.
FAQs
What does wall spacing control?
Wall spacing sets how frequently boards appear along edges. Smaller spacing increases coverage and capture probability, but it raises board count and labor. Use tighter spacing in cluttered or high-activity zones.
Why do I need interior boards?
Interior boards reduce blind spots in open areas where pests cross away from walls. They are most useful on large floors, corridors, and staging zones where perimeter-only layouts miss activity.
How should I treat entry points?
Treat entries as hotspots. Place at least two boards per entry, one on each side when possible, and keep them just inside the threshold. This helps detect incoming movement early.
What risk level should I choose?
Choose low for clean, sealed spaces with limited traffic. Choose medium for mixed-use areas and routine deliveries. Choose high for food, moisture, waste handling, or frequent material movement.
What buffer percentage is practical?
A 5% buffer fits stable sites with low damage risk. Use 10–15% when boards are exposed to washdown, dust, or frequent relocation. Buffers prevent missed checks when boards must be replaced.
How often should boards be inspected?
Inspect daily in high-risk or high-traffic areas. Weekly works for stable rooms with low findings. Increase frequency immediately after any capture, then normalize once trends decline and controls are verified.
