What recipie have you found to be the most acceptable to the bees?

What do they not like?

At what point do you offer it and is it left out or only put out in good
weather?

If you "could" add  or subtract something what would it be?

What might be added to make it more attractive to the bees? Its clear they
dont appreciate it and use it only as a last resort.


Thank all who offer their insights and experience!
