In rummaging around I found a little screening with 1/8" holes, and I assume that's #8 screening, which is supposed to be good for screened bottom boards, if I understand correctly.
I also found a lot more screening with 3/16" holes. The wire is, of course, also thicker. What would be the effect if I used this for screened bottom boards?
I assume the bees could walk on it just fine. The mites could still fall through the holes, but the thicker wire might allow them to stay on the screen ... which isn't good.
Does anyone have any experience with this coarser wire mesh in a screened bottom board?
