Size your bait program before placing any stations. Choose method, spacing, and infestation severity today. Reduce waste, track refills, and protect pets nearby always.
| Scenario | Method | Size | Spacing | Infestation | Form | Refill / Duration |
|---|---|---|---|---|---|---|
| Backyard shed zone | Area grid | 120 m² | 4 m | Moderate | Block | 7 days / 21 days |
| Fence line protection | Perimeter line | 90 m | 6 m | Low | Pellet | 10 days / 30 days |
| Compost corner | Custom stations | 10 stations | — | High | Paste | 5 days / 20 days |
Suggested doses (if left blank) are based on bait form and infestation level. You can override them if your product label specifies a different station load.
Always keep bait secured and inaccessible to children, pets, and wildlife. For active infestations, shorten refill intervals until consumption stabilizes.
Effective baiting starts with a clear map of travel routes: along fences, walls, compost edges, shed perimeters, and dense cover. This calculator converts area, perimeter, or a manual station count into a practical estimate. Area mode uses a grid concept where each station represents coverage based on spacing. Perimeter mode places stations along a line for boundary layouts. Review access points, pet exposure, and moisture. Then set spacing accordingly so stations remain secure, for inspection, and consistent across the site, from week to week.
Bait form and pressure level influence how much material should be available at each station. Blocks hold up in damp conditions, pellets deploy quickly in protected boxes, and paste suits controlled placement. If dose is blank, the calculator suggests grams per station by form and level, which you can override to match the label.
Rodent activity changes quickly, so planning refills prevents gaps. The calculator estimates fill cycles using program days divided by refill interval, rounded up. Shorter intervals improve control because stations are checked before bait runs out. Longer intervals reduce labor but increase uncertainty during high activity, cold nights, or after harvest shifts.
Real-world work includes losses from weather, minor spillage, insects, and partial consumption. Waste allowance adds a percentage buffer, while the safety factor adds a multiplier for uncertainty. Together, they help ensure enough material is on-hand without emergency purchases. Record actual usage and adjust these settings on the next run.
Example: Area 120 m², spacing 4 m, block bait, moderate level, refill every 7 days, program 21 days, waste 10%, safety 1.00. Stations = ceil(120/16)=8. Cycles = ceil(21/7)=3. Total = 8×40×3×1.10×1.00 = 1056 g (1.06 kg). Use this pattern to compare options.
No. Use this as a planning estimate for purchasing and logistics. Always follow the bait label for allowed placements, station loading, and inspection frequency.
Use area for open zones like garden plots, perimeter for fences or walls, and custom when you already know the station count from a site walk-through.
Choose a spacing you can maintain consistently and safely. Tighter spacing increases stations and bait needs, but often improves control where activity is concentrated.
Rounding up prevents under-ordering. If your program spans part of an interval, you still need product available for that check and top-up cycle.
Increase it for wet weather, insect pressure, repeated spillage, or when stations are exposed. If conditions are controlled and records are good, you can reduce it later.
It multiplies the final total to cover uncertainty in activity, access, and consumption. Use 1.00 for stable sites and higher values for variable, high-pressure situations.
Log station locations, refill dates, and grams used. Update spacing, dose, and intervals based on observed consumption until it stabilizes at low, predictable levels.
