Don't know about excluders, but I found there is some difference. Some years ago I took a New Zealand made pollen trap with me home to try. The bees got really upset about it, and when I checked it out they couldn't get through the holes. So my bees got to be bigger than Kiwi bees....... without renewing the combs too much. I think it's more a genetic factor, when NZ allows very little import of new genetic material (if any). I think it was about 2/10 of a millimetre too small. Only a few bees could squeeze through. -- Regards P-O Gustafsson, Sweden [log in to unmask] http://www.algonet.se/~beeman/
