摘要：
A nest box (1) for bumblebees that provides sufficient ventilation inside the nest box (1). The provided nest box (1) with a bumblebees hive (2) inside resolves the problems of insufficient ventilation, by being mounted with a ventilation panel (14), comprising ventilation holes (13) in size(s) that enable ventilation but at the same time bumblebees from passing through.
