Greetings,
I would have thought that the size of the openings was very important. My
feeling would be that the varroa would not readily fall through fly
screening. Most of the references to screened bottoms seem to use 8 openings
per inch. Of course the size of the opening would differ with different
gauge wire but there is a Standard Mesh size in the U.S. and this is what
all North American beekeepers would have available to them. Has any one
tried 6 mesh? This would allow the mites to fall through more readily but
would the bees have difficulty walking on a more open bottom?
