> I have been using this type of floor for nearly twenty years and > I would be unlikely ever to use a solid one in future. I am looking seriously at using screened bottom boards starting next year. I have read here in the past that 6 mesh is the perfect size, but that it is hard to find. I understand that 1/4" and 1/8" mesh are easier to find, but 1/4" will not keep out the wasps. Two questions: 1) Will varroa reliably fall through a 1/8" mesh? 2) Does use open mesh floors promote raiding of hives by small ants?
