Langstroth Under Hive Entrance Board

Under hive entrances help with wind and guards against Wasp, Hornet and Mice.  The small entrance is longer to navigate for robbers to gain access to the hive.  This provides a much greater chance for the colony, no mater the size, to guard the entrance.  The floor entrance is 8mm  wide and can be easily navigated by the bees but does not allow mice to enter.   

With a pressure fit ¼ Steel Nut, an OAV Nozzle Vaporizer can be inserted for a 60sec. treatment and not harm the plastic port. 

May also be flipped as a quick top entrance lid or no entrance if used upside down.

10 Frame hives can be supported with (2) 4 frame boards placed side by side. 

Print Directions:

For small bed printers, I have split the part and the front/back wall can be placed on the bed printing vertical.  PETG may be best for outside usage.  Supports are not needed.
