How to Use This Calculator
  1. Enter Number of Hives, Treatment Type, and Infestation Level.
  2. Review Treatment Urgency and Total Doses Needed.
  3. Use Treatment and Treatment Duration (days) to inform your decision.
  4. Use the chart to visualize the results and explore different scenarios by adjusting inputs.

What each input means

Number of Hives
Total hives to treat. All hives in an apiary should be treated simultaneously.
Treatment Type
Treatment: 1 = Oxalic Acid (1 day, broodless), 2 = Formic/MAQS (7 days), 3 = Thymol/Apiguard (42 days), 4 = Amitraz/Apivar (42 days).
Infestation Level
Mites per 100 bees from alcohol wash or sugar roll. Treatment threshold: 2–3%. Above 5% = emergency.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Number of Hives = 4, Treatment Type = 4, Infestation Level = 3 = 3 input(s) provided
  2. Calculate Treatment Urgency
    High — Treat immediately = High — Treat immediately
  3. Calculate Total Doses Needed
    Total Doses Needed
    8 = 8
  4. Calculate Treatment
    Treatment = treatment.name
    Amitraz (Apivar Strips) = Amitraz (Apivar Strips)
  5. Calculate Treatment Duration
    Treatment Duration = 1
    42 = 42
