Betreff: Wire Mesh Bottom Boards
Hello Ernest,
WMBB are very often used here in Germany since many years. I have those
boards in more than 90 % of my hives. But it's no instrument for fighting
varroa, just for controlling the number of varroa in my hives before and
during medicamentation period.
The hives are used with these WMBB during all seasons.
>What size mesh to use?
Usually size mesh is about 4 mm. Varroa mites have a size of less than 2 mm.
So bees cannot pass through the mesh boards. Cooling the hive doesn't need
passing because ventilation of the bees works quite well through the WMBB if
necessary at all.
By the way I prefer WMBB made of plastic material (unexpensive) or stainless
steel (very durable).
Sincerely
Reimund
