Improve hive ventilation

Improving hive ventilation is a key strategy for managing chalkbrood. Chalkbrood fungus thrives in damp, poorly ventilated hive environments. Increasing ventilation helps to reduce moisture levels within the hive, making it less favorable for fungal growth. This can be achieved by adding screened bottom boards, which allow for increased airflow from below, or by creating upper entrances to promote cross-ventilation. Reducing hive moisture is crucial in preventing and controlling chalkbrood. Simple modifications to hive structure can significantly improve ventilation. A screened bottom board is a commercial solution for enhanced ventilation, while a drill can be used to create upper entrances in existing hive bodies.
