Estimate bait placement for safer site pest control. Adjust species, area, and product strength quickly. Always follow label rates and local regulations strictly onsite.
| Scenario | Gross Area | Mode | Rate (g/m²) | Spacing (m) | Rounds | Estimated Stations | Estimated Total Bait |
|---|---|---|---|---|---|---|---|
| Warehouse perimeter | — | Perimeter (120 m × 2 m) | 6 | 3 (perimeter) | 2 | ~92 | ~3.0 kg |
| Open storage yard | 800 m² | Full area | 5 | 6 (grid) | 1 | ~26 | ~4.2 kg |
| Mixed site, high pressure | 1,200 m² | Full area | 8 (capped at 12) | 5 (grid) | 3 | ~61 | ~38 kg |
Construction sites attract rodents where food waste, standing water, and stacked materials exist. Map hot spots within 20–30 m of dumpsters, canteens, and laydown yards. Use notes from inspections: droppings, burrows, gnaw marks, and runways near conduit trenches. Pair baiting with housekeeping and sealing gaps around doors to lower consumption and reduce repeat dosing significantly. Enter the gross area, then subtract excluded zones such as kitchens, drains, and sensitive storage. The calculator uses the remaining treatable area to prevent inflated bait totals.
Station spacing controls coverage and service time. For open yards, a 5–8 m grid often balances coverage and labor, while high-pressure areas may need 3–5 m. Perimeter programs usually place stations every 2–4 m along fences and walls, focusing on entry points. The station estimate is based on treatable area divided by spacing², or perimeter length divided by perimeter spacing.
Bait labels typically specify an application rate or a maximum amount per area. Use the label rate field to match your product scenario, then enable the max-rate cap to avoid exceeding site policy. If the label rate is higher than the cap, the calculator automatically uses the lower value, keeping the estimate conservative and compliant.
Many projects require chemical inventory reporting. By entering the active ingredient percentage, the tool converts total bait into an estimated active ingredient mass. For example, 0.005% equals 50 mg per kilogram of bait. This supports toolbox talks, method statements, and audit trails, especially when multiple rounds are scheduled.
Rodent programs rarely succeed with a single placement. Set rebait rounds to reflect weekly checks or refill cycles, then add wastage and safety allowances for weather damage, dust, and handling loss. Common planning ranges are 5–15% wastage and 0–10% safety, but always stay within the label. Export CSV or PDF to share calculations with supervisors.
Enter the rate stated on your product label for the site type and target species. If your label lists different rates for indoor, outdoor, or burrow work, choose the matching scenario.
Perimeter mode calculates a band area using perimeter length × band depth, then applies the same rate and adjustment factors. Stations are estimated from perimeter length divided by perimeter spacing.
Mice typically have smaller home ranges and may need denser station placement. The calculator applies a modest species factor to increase station count when you select mice or mixed activity.
No. It estimates quantities and station counts. Placement should follow a site survey, structural entry points, label requirements, and your safety plan, using tamper-resistant stations in appropriate locations.
It helps with documentation, inventory control, and audit reporting by converting your total bait estimate into an approximate active ingredient mass based on the percentage you enter.
Improve waste control, remove standing water, and keep materials off the ground where possible. Seal gaps around doors, service penetrations, and store food securely. These steps reduce rodent pressure and rebait frequency.
