onto the cloth collector tray.  If you block the debris then you also block
the pollen and the bees will pick it up again.   The posting with the
pictures of the front mounted trap is almost exactly the trap I saw in
Chile, although the plastic scraper did not have the fancy ridges between
the holes.  Much nicer as several people are advising you, Peter.
