BAYVAROL STRIPS are a highly efficient remedy against varroatosis. When applied according to the directions for use, the bee colonies can be protected from Varroa induced collapse in the late summer. Moreover BAYVAROL STRIPS help in the development of healthy winter bees and guarantee the hibernation of strong bee colonies. A change of nowadays control strategy is possible only when breeding of bees resistant to Varroa jacobsoni will succeed (Büchler, 1992).
