Drone brood frame

Some acaricides used in alternative control strategies against Varroa, such as formic acid or essential oils, do not always provide sufficient efficacy. As complementary measures, we recommend the removal of drone brood or the establishment of young colonies in spring. These interventions aim to slow the development of Varroa populations and thereby reduce infestation pressure. They have the advantage of being applicable during the main beekeeping season, whereas the use of chemotherapy would entail significant risks of contaminating honey harvests.
