Queen Excluder

[Millet]

I think i know a hive has to have around a 6mm to 8mm bee space..but what should the spacing be in the queen excluder..

The hole size is usually around 4.3mm - which I think is what you are asking about.

Slight differences depending on how it's made. See this page on Dave Cushman's site. http://website.lineone.net/~dave.cushman/excludertypes.html
