Re: Rethinking my beekeeping theology - Bottom boards: screened or solid?
I have been keeping bees for many years and have never even seen a screened bottom board let alone used one. When your making increase next spring Westernbee why not set up a group of hives without them and see what happens for yourself. My bees here seem to do a very good job of suviving without any treatements. Randy Oliver passed through here a couple years ago and commented that out mite loads are very low from what he observed. Keep using your own genetics from your survivor colonies and you should be fine. I tend to cringe now when people start talking about package bees from California. Keep it simple up there.
