Increase ventilation

Increasing hive ventilation is crucial for dissipating heat and preventing overheating. Adequate airflow helps bees regulate hive temperature through evaporative cooling and heat exchange. Ventilation can be improved by using screened bottom boards, which allow for greater airflow through the hive floor. Adding upper entrances or shimming hive bodies (slightly separating hive bodies) also enhances ventilation and heat escape. Increased ventilation is particularly important in hot and humid climates or during heat waves. Screened bottom boards and upper entrances are common ventilation modifications.
