I've been using this forum to learn about different hive configurations for different kinds of beekeeping and I've become more curious about the screened bottom boards.
Locally I was told that the purpose was to use it in the Fall with a sticky paper to establish a mite count.
Here it seems that some people use a screened board for genereal hygenic purposes all year long.
Does a screened board also improve ventilation during warmer weather?
Are there other uses / purposes for a screened bottom board?
