Boy, ain't that the truth!! That is my situation - I am a 2nd year beekeeper, and all I have is undrawn plastic honey super foundation. They have hardly touched it. I am told it is because they need a good nectar flow to make the wax.It seems that getting plastic frames drawn out the first time is the hardest.
It's a catch 22 in a way - I could feed 1:1 sugar syrup to get them to make wax, but then they'll just store the sugar in the super. Too bad there's not a secret ingredient you can add to the sugar which says "just use this sugar to make wax, but don't store any of it..."
