With the Varroa Check you can easily count the number of Varroa mites in your bee colony.
1. Collect 200 to 300 bees. There are two lines in the container: the bottom line corresponds to about 200 bees, the top line to about 300 bees.
2. Add flower sugar, close the lid and shake the bees for 1 to 2 minutes.
3. The mites and flower sugar fall at the bottom. Remove the container and return the bees to their hives. You can count the mites at the bottom. Tip: add a little water, then the sugar will dissolve and you can see the mites well.
How to interpret?
By dividing the number of mites by the number of bees, you can find out the level of infection. So with 10 mites on 300 bees, you have an infection rate of 10/300 of 0.03 = 3%.
It is recommended to treat the bees against the Varroa mite when the infestation rate is greater than or equal to 5%.
