I still have a couple supers of wet frames I want to put on my hives and I am concerned about giving them more comb than they can take care of. It seems that with the wet supers I've put back on, they don't just clean the comb, they keep much of it in that super and are adding more pollen and possibly nectar. We have groundcover wildflowers blooming, not sure what they are but I assume they are nectar producers.

If I were to force down the bees they would probably fill 8 seams of a 10 frame box. I don't think I can pull supers off for storage when there is still pollen and nectar, correct? How do I know when I'm giving them more comb than they can care for? The bees on most days here are very active.
Thanks.
