Plan accurate mixing using your product label rate. See total spray, concentrate, refills, and per-tank amounts. Keep people and pets away until treated areas dry.
| Scenario | Area | Coverage | Mix rate | Tank | Coats | Waste | Output (spray) | Output (concentrate) |
|---|---|---|---|---|---|---|---|---|
| Small room edges | 200 ft² | 1000 ft²/gal | 10 mL/L | 1 gal | 1 | 10% | ~0.22 gal | ~8.3 mL |
| Two rooms, two passes | 450 ft² | 800 ft²/gal | 12 mL/L | 2 gal | 2 | 15% | ~1.29 gal | ~175 mL |
| Metric setup | 30 m² | 10 m²/L | 0.3 fl oz/gal | 5 L | 1 | 10% | ~3.30 L | ~7.7 mL |
This calculator scales a treatment plan from the label values you enter. Area and coverage are converted to a consistent metric basis, then reported back in your chosen units for readability. Enter the exact label coverage statement and the exact concentrate mix statement, including the correct unit type, to keep your calculation aligned with compliant directions and recordkeeping. Double-check decimals and avoid mixing square and liquid units.
Coverage typically drives finished spray volume more than any other input. Smooth sealed surfaces may achieve label coverage, while porous or textured materials can increase demand. Use coats to represent multiple passes and use waste/overlap to represent edging, seams, and unavoidable losses at the wand and hose, instead of changing the label mix rate. If unsure, start conservative and test a small section first.
Tank size affects workflow and mixing steps, not the pesticide label itself. The tool estimates refills by dividing total finished spray volume by tank capacity and rounding up, then provides per‑tank concentrate for consistent batching. This supports staging water, keeping a steady walking pace, and avoiding rushed partial mixes that can produce patchy coverage. Record batch counts to compare planned volume with actual usage.
The mix rate is normalized to milliliters per liter and multiplied by total finished spray volume to estimate concentrate required. Strength factor is a visible multiplier and should stay at 100% unless the label explicitly permits an adjustment. Measure concentrate with a graduated cylinder or syringe, mix in a ventilated area, and agitate the tank as directed. Label agitation timing matters for suspensions and emulsions too.
Use outputs as planning numbers, not as permission to apply. Apply only to label‑approved sites, especially indoors, and respect re‑entry and drying guidance for people and pets. For bed bugs, combine chemical steps with laundering, heat, vacuuming, encasements, clutter reduction, sealing cracks, and monitoring traps, then schedule follow‑up inspections to disrupt the life cycle. Avoid treating electrical outlets unless the label clearly allows.
It does not choose a pesticide or rate. It only scales the area, coverage, and mix rate that you enter from a product label, then estimates total finished spray, concentrate needed, per-tank concentrate, and tank refills.
It is a transparent multiplier for scenarios where a label specifies different dilution options. Keep it at 100% for standard label rate, and only change it when the label explicitly allows an alternative dilution for the same use site.
No. Changing dilution beyond the label can be unsafe and illegal. Use additional label-approved applications, improved preparation, and integrated control steps instead. If infestation persists, consult a licensed professional or local guidance.
Use it for edge overlap, seams, porous surfaces, and small handling losses. Typical planning ranges are 5–15%, but select a value that matches your application method. Do not use waste to justify higher concentrate dilution.
A consistent internal unit system reduces math errors when users enter ft²/gal or m²/L and mL/L or fl oz/gal. The calculator converts, computes, and then displays results in your chosen tank unit for easier mixing.
Only if your product label approves that specific indoor use and location. Many products restrict application to cracks and crevices. Follow PPE, ventilation, drying, and re-entry instructions, and keep people and pets away until treated areas dry.
