<< Will the screens  remove mites into the pollen?  Has anyone experience
 with this?>>

It's true. Mites will fall into the pollen collection tray - it's
unavoidable. Last summer, as I was cleaning my pollen trap from the various
bee body parts that had fallen, I discovered my hive had a contamination of
Varroa. By the way, these mites were dead. Don't be alarmed, it isn't unusual
to find live, crawling insects like black ants trying to co-exist in this
area, too.

So, there are 2 ways to view this - (1) it's an early warning system of a
mite problem and (2) you can move the trap to another hive that may be
mite-free. Of course, some may add a third item, the benefit of added protein
into the mix of pollen :)
