I am new to beeking, trying to start 3 hives this year. I'm building my own hives. Presently I'm trying to figure out how to make the bottom boards. I have window screen, will that work? Or do I need special screens.
Welcome, if you are screening the bottom boards for Varroa control, so bad stuff can fall out, window screen is too fine. Screen needs to be number 7 or 8, 8 wires per inch. The plans are actually on this website.
We use 1/8" hardware cloth on ours.
