I don't understand that. If you're going to start a thread like this one at least have have a suitably thick skin to see it through *or* accept you're wrong if you realise that you are. But disappearing almost as soon as you've arrived. What's the point of it all?

This is my favourite WBC. If you look closely you pull a drawer out the back, to put in a corex board. Nice and snug. Similar to your idea.

. I'll definitely go ahead with my plan A. 
Where did you get that idea ?
Many people do. Where I live a fully open OMF equates to leaving a house window open most of the time, that is cold air, draughts and often a modest gale blowing in. With the inspection tray "in" there is still a place for varroa to drop through and, dare I say it enough air leakage to be called ventilation.
That's a real shame because all of us mods strive to keep this place as democratic and safe as possible while still alive and kicking. We don't remove content unless its confrontational on a personal basis, legally unsafe or just plain rude. I think you are wrong
Most varroa that fall through the OMF are dead. Have you ever seen varroa move? they are pretty fast and I would hazard that any loose ones in the colony fairly soon drop on to a neighbouring bee. For one varroa to fall from a bee and not encounter another before it hits the mesh must be rare.
Nonsense - seen very little in the way of 'censorship' here - apart from the odd vile post which shouldn't have existed in the first place
No - another myth, OMF has little to do with varroa control (apart from being a very inefficient way of monitoring mite levels) it's all to do with air circulation and temperature balance.
