Removing the entrance restrictor on a honeybee hive without smoke or protection by www.beinggreenonline.com. I tried to change my hive from a bottom entrance to a top entrance by blocking the bottom entrance with a piece of wood, the honeybees chewed through some wood to create their own entrance and refused to use the top entrance. Since we’ve entered the blooming season I decided to take off the restrictor so their work is not impeded.
