How Many Varroa Mites Are in Your Hive? — Sheet 1

Reviewed notes and corrections

Calculate adult-bee infestation as counted mites divided by sampled bees, multiplied by 100. Record the sampling method and actual sample size, exclude the queen and compare like with like. Sticky-board counts are a different measure and cannot be read as an infestation percentage. A 3% example is not a universal action threshold for every season or region.
