These wooden entrance reducers fit snugly in the opening between the bottom board and your first brood chamber to control the size of the entrance to the hive.

They should be left all year round as follows: 

  • smallest opening for best protection on smaller populations or when robbing is an issue
  • largest opening for larger population to avoid traffic jams

Pick the right size for your equipment so they fit properly.
