I really don't know much about propolis, except why they make it and what its used for. I don't know really what it is and why they are making so much this time of year. It seems to be a reddish color and everywhere. With the heat it's very sticky like chewing gum.
I believe that Demeter is ready to have the medium of honey pulled off so I put in a bee excluder between the two deeps and the medium. The bees can go back down into the deeps, but can't re-enter the medium. Hopefully I can just go pull the whole medium off and it be bee free tomorrow a.m.
