Screened Bottom Boards as trampoline
Extensive long term studies at Cornell University have demonstrated
that screened bottom boards do not reduce mite build up in colonies.
I think they are a waste of money. The mites that fall through them
most likely are old and about to die anyway.
However, if the bees use them as trampolines, well -- I guess they
are entitled to a little bit of fun before we put them to work
gathering honey for us!!
