On June 30, 2026, Dr. Hannes Beims (representing the ring test group) discussed the practical testing of Calistrip BIOX for Varroa treatment. This German field trial explores the potential and limitations of using oxalic acid strips for Varroa control.

To maintain a "low brood quantity," queens in the test colonies were confined to two frames. Since late summer 2025, oxalic acid strips have been approved in Germany for treating bee colonies against Varroosis. A collaboration of various organizations and beekeepers has been gathering initial results from practical applications across different regions in Germany. The new strips were used according to their approval guidelines and assessed for usability and effectiveness.
