Can anyone help with excluder sizes.

I am curently looking into taking up beekeeping and have been reviewing hives & designs. The source info at this site has been most useful. The information that curently eludes me is the size of and shape of holes in excluders.

There appears to be a bewildersin variety of types slotted, wire round holes etc

Which is most effective and dose least damage to the bees. Does the size vary for diferent strains and so on.

The FAQ'a I have rooted through all seem to miss this bit, whilst excluder use appears to be prolific..

Help


Cheers
