Screened Bottom Boards for ventilation & controling pests

seemingly they can just slip through the mesh.

Hi Matthew,

Since your post, my Flow hive has arrived, and I now realize that I was wrong. Although the Bee Thinking SBBs have #8 hardware cloth, the Flow SBBs use #6. There is a discussion about it here, along with some photos I took of my Flow SBB next to a Bee Thinking SBB:

Bees between the bottom screen and the pull out board

I understand what you are saying Matt, but just to add some info, here is a photo of the whole SBB before I moved the wires to even out the mesh. The widest points were over 6mm, some close to 7mm. I think that may become an issue to Flow customers. [image] Now I have fixed the spacing, the mesh looks OK, but I actually fixed it before I realized it was #6 mesh. I can see Flow’s reasoning, but I really think it is worth reconsidering, I am delighted that you are going to discuss it with Cedar. …

I think I am going to dismantle the Flow SBB and change to #8 mesh, because I really don’t want my bees going through that screen.
