I want to build a robber screen for my two top bar hives which have entrances on the front, but to the side. As a result of being on the side, I have a 60 degree angle to contend with which does not allow me to build a traditional Langstroth robber screen as I quickly hit the sidewall with the screen. I certainly cannot go the 4" that I oftentimes see recommended as the minimum height.
If I build a screen that is enclosed on the top and bottom, but has gaps on the side will robber bees be able to more easily access the hive? How small should the gaps on the side be?
When I eyeball it, it seems like the gaps are fairly large and might prove ineffective.
Thanks for any thoughts.
