Subject: Re: opening size

Thanks Dave
Sounds like a neat contraption . This queen excluder above the entry
probably also effects swarming unless the queen can squeeze through there.
One method I know of is the use of an excluder between the isolated queen in
an upper broodbox and an Imirie frame to let the workers enter and exit.
That indicates that she is not small enough to pass through the excluder.
Everyday more to learn .
As far as mouse size is concerned . May not all mice are the same either.
Here we have an abundance of field and wood mice
I have no idea what there are but they are good looking but of no use in the
hive.
