Mite Count Efficacy Calculator Guide

The Mite Count Efficacy Calculator grades your treatment performance based on pre and post mite counts.


How to use it:

  • Enter your pre-treatment mite count (per 300 bees)
  • Enter your post-treatment mite count (per 300 bees)
  • Click Calculate to see your efficacy grade

    • Understanding the grading:

  • Grade A (90%+): Excellent — treatment performed as expected
  • Grade B (70-89%): Good — acceptable result, monitor closely
  • Grade C (40-69%): Below target — consider factors that may have reduced efficacy
  • Grade D (below 40%): Poor — investigate application method, product expiration, or resistance

    • Factors affecting efficacy:

  • Temperature during treatment (critical for organic acids)
  • Brood presence (sealed brood shelters mites from most treatments)
  • Application method and technique
  • Product storage and expiration
  • Potential resistance in your mite population
