Pollen Trap Yield Calculator
Estimate daily and seasonal pollen harvest from your beehives based on colony strength, trap efficiency, and bloom period.
Pollen trapping allows beekeepers to harvest fresh bee pollen for sale or personal use. A pollen trap fits over the hive entrance and strips a percentage of pollen loads from returning foragers.
Core Formula: Daily Pollen Yield = Colony Foragers × Trips per Day × Pollen per Trip × Trap Efficiency
Key Variables:
- Colony foragers: A strong colony (60,000 bees) has roughly 20,000 active foragers. About 25–30% of foragers collect pollen on any given day.
- Trips per day: Each pollen forager makes 6–10 trips daily during peak bloom.
- Pollen per trip: An average pollen load weighs 15–20 mg (0.015–0.020 g).
- Trap efficiency: Standard bottom-mounted traps capture 50–70% of incoming pollen loads. Higher-efficiency front-mount traps reach 60–80%.
Worked Example: Colony with 15,000 foragers, 28% are pollen foragers, 8 trips/day, 17 mg per load, 60% trap efficiency:
- Pollen foragers = 15,000 × 0.28 = 4,200
- Daily loads = 4,200 × 8 = 33,600 loads
- Raw pollen = 33,600 × 0.017 g = 571 g
- Trapped pollen = 571 × 0.60 = 343 g/day (about 12 oz)
Seasonal Yield Reference:
| Season Phase | Duration | Daily Yield | Total |
|---|---|---|---|
| Early spring | 3 weeks | 100–200 g | 2–4 kg |
| Peak bloom | 4–6 weeks | 250–500 g | 7–21 kg |
| Late summer | 3 weeks | 80–150 g | 1.5–3 kg |
Important: Never trap pollen continuously for more than 2–3 days at a time. Bees need pollen to raise brood. A recommended schedule is 2 days on, 5 days off, or 3 days on, 4 days off. This calculator accounts for a trap-on ratio you specify.
Fresh pollen should be frozen or dried within 24 hours of collection. Dried pollen sells for $15–$40 per pound depending on floral source and region.
