Varroa i fights them more effectively by zeroing out the winter brood. From this observation comes the Menna cage, designed and patented by Vincenzo Menna: a practical device that promotes the queen's rest in the colder months, and that brings all the varroa present in the Beehive more easily out into the open. The period of use varies from northern to southern Italy, but indicatively the first days of November will be the most suitable to start caging, and mid to late January those for caging. Considering that a regular family goes into production in 60 to 70 days from the release of the queen, it will be up to the beekeeper to adjust the period.
