Fill with liquid (anti-freeze liquid or alcohol) up to half of the container. Take the bee sample with the container;
Separate the varroe from the bees by gently shaking for 60 seconds;
Count the varroe that has fallen to the bottom and estimate the infestation.
Calculate the estimate of the infestation <6 varroe on 300 bees: we are below the safety threshold; between 6 – 15 varroe: must be treated quickly; > 15 varroe: treat immediately.
How many hives to sample? 1-5 hives → all; 6-20 hives → at least 5; > 20 hives → at least 8.
