Before I built my own, I saw one built by a chap at the far side of my
county and it had a mesh floor. We became friends, briefly, and I once
supplied him with a spare queen. 'Briefly' because his other hobby was
hang gliding, which killed him!
Back to the subject, if your combs are crossed from bar to bar you
aren't looking at them often enough! Certainly, given a chance, they
tend to build comb in curves but, if found soon enough, it can easily
be persuaded back on line with a, gently applied, hive tool. Sometimes,
it helps to turn a bar around so that it faces a comb that the
beekeeper considers to be appropriately drawn.
I haven't yet tried mesh floors in TBHs. I have, so far, experienced
little in the way of varroa related problems therein. Generally I
treat with thymol in the Autumn (Fall in the US) and a dose of oxalic
acid solution around the shortest day.
