They do drop a lot and I've noticed that it sometimes depends on the type of pollen, or maybe the time of year. Not sure. I've seen other times when the bees are bringing in lots and lots of pollen and there's very little on the bottom board.
I'm wondering what you are all talking about. It sounds like you are talking about the pollen that we beekeepers dump out of the combs when we manipulate them. I haven't seen any pollen dropped by the bees, only that which I dump out of the combs when I manipulate them.
No..I do get pollen drops. Not all the time, but certain times of the year you would think I have a pollen trap on. For a week or so, there's a lot of pollen on the bottom board or even the screened bottom board. Then, it's over.
the type of mouse guard I used that year is exactly the same mechanism a pollen trap uses to strip pollen off their legs
I've stopped using mouse guards at all, I think our winters are mild enough the bees can take care of their selves
of course folks farther North have different issues
