I bought one in January while skiing up north. Stopped into a bird store and there it was.

Now that I've been reading around the forum, it seems the plastic tray design isn't the best to use.

I watched Dave's video on drilling and inserting the paper tubes and I'll probably go that route instead.

Some questions:

1) should I not even bother putting the plastic tray house out?
2) should I replace the plastic tray with wood blocks drilled and lined with paper?
3) Do I 'need' to clean the tubes each year? I had thought I would get into mason bee keeping and just set the blocks and forget about the.
