4.8.1 Observation at the Hive Entrance

Observation at the hive entrance makes it possible to draw numerous conclusions about the health status of a bee colony. Especially in spring, it is important to assess colonies in this way. Anomalies indicate the aspects that require particular attention during the next colony inspection or when an additional examination becomes necessary. Observation at the hive entrance also helps to avoid interventions within the colony under unfavorable weather conditions.
