trap out complete - one question left

[dfizer]

Hello all -

I have completed a trapout which was started about 2-1/2 months ago.  NO bees are coming out of the cone whatsoever, furthermore there has been no activity from the tree entrance for at least 4 days.  The hive will be removed in the next day or so.  The only question I have is what to do with the old entrance / hole in the tree where the bees were before?  Perhaps seal it up with a small piece of plywood?  Any suggestions for sealing up the old hive location would be great.  The hole is about the size of a tennis ball.  The only goofy criteria I am working with is - this tree is in the middle of someone's front yard and they want it to be very "unnoticeable". 

Please advise.

I'd feed it a can of Great Stuff!  :-D

We filled with spray foam the glued some bark from the same tree onto that so it didn't show.

I would call an arborist and get the filler they use.
