Can anyone tell me the maximum gap size I can have in a bee/small-hive-beetle separator and still be assured of not having any bees squeeze into the beetle's area? The goal is to have about 1/8 inch gap. However, wood tends to warp across long distances, so the question becomes how tight the tolerance needs to be.
Is a gap of 0.150 inch acceptable, or can some bees squeeze through a gap this size?
Thanks, Tim Stout
