Example data table

Example outputs are illustrative. Use label rates for your exact product.

Formula used

Convert area to square meters: m² = ft² × 0.09290304.

Base bait per application: Base(g) = Area(m²) × Rate(g/m²) × SeverityMultiplier.

Add buffer: PerApp(g) = Base(g) × (1 + Buffer%/100).

Total bait: Total(g) = PerApp(g) × Applications. Cost: Total(kg) × PricePerKg.

How to use this calculator

1. Measure the treatment area in m² or ft².
2. Select your product type, or choose custom from label.
3. Pick the infestation level based on observed activity.
4. Set applications to match your planned re-check cycle.
5. Add a small buffer if you expect spillage.
6. Press Calculate to see totals above the form.
7. Download a CSV or PDF for job notes and records.

Understanding pellet coverage

Snail bait works best when pellets are spread evenly, not piled. The calculator converts your area to square meters, then multiplies by a rate in grams per square meter. This produces a per-application quantity that supports consistent spacing across beds, borders, and containers. For small plots, measuring only the affected zones improves accuracy and reduces waste.

Choosing a label rate

Every product label specifies a permitted application range. Rates differ because active ingredients and pellet density vary. Use the built-in presets as a planning baseline, then confirm your exact label value. If your label shows a single rate, select Custom and enter it. When converting from label units, keep grams and square meters consistent. If your label uses pounds per 1,000 ft², convert carefully before entering a custom rate in the calculator. The tool also reports a reference range per application to help you spot unrealistic inputs.

Adjusting for infestation pressure

Slug and snail activity changes with moisture, plant tenderness, and shelter. The infestation multiplier lets you scale the plan without changing the label rate. Low pressure uses a smaller multiplier, while outbreak conditions use a higher one. This helps when damage is concentrated near irrigation lines, mulched edges, or shaded walls where nightly movement is highest.

Planning repeat applications

Most gardens need more than one application because new pests migrate in, and pellets break down in rain and irrigation. Enter planned applications to estimate total product requirements for a treatment window. As a rule, recheck after about 7–14 days depending on pressure. Reapply only as the label allows, and remove debris that creates hiding sites.

Managing cost and safety

Adding a price per kilogram provides a quick budget estimate for purchasing and scheduling. If cost rises, reduce the treated footprint to priority plants rather than lowering the rate below label guidance. Keep pellets away from ponds, drains, and pet feeding areas. Sweep spills, store containers sealed, and choose safer options when children or pets visit regularly.

FAQs

1) Does the calculator replace the product label?

No. It estimates quantities from your area and a rate, but the label sets legal limits, timing, and restrictions. Always follow the label and local regulations for safe, compliant use.

2) What area should I measure?

Measure only the zones you plan to treat, such as bed edges, mulched borders, or container groups. Excluding unaffected areas improves accuracy and can reduce cost without lowering the application rate.

3) Why use the infestation multiplier?

Pressure varies with moisture and shelter. The multiplier scales planning quantities for low, medium, or outbreak conditions while keeping the chosen label rate intact. It helps you plan totals for the same product more realistically.

4) When should I choose a custom rate?

Choose Custom when your label lists a specific rate, or when you have verified conversions from other units. Enter the rate in g/m² so the tool can calculate per-application and total bait correctly.

5) How many applications are typical?

Two to three applications are common during active periods, but rainfall, irrigation, and reinfestation can increase needs. Recheck after 7–14 days, and only reapply at intervals and totals permitted by the label.

6) How can I reduce risk to pets and wildlife?

Apply sparingly and evenly, avoid water features, and remove spills immediately. Store bait sealed and out of reach. Where pets or wildlife are common, select lower-risk products and use physical barriers and habitat cleanup.
