Re: Ways to reduce space in an 8-frame medium?
I've heard that bees will destroy the styrofoam, but I have no experience with it myself. There is a difference between a follower board and a division board. The follower board has beespace around the edges, the division board does not. You could cut out some division boards to seal off area. You can also use the division board to divide an 8 frame box into side by side 4 frame mediums, so having 2 nucs contained in single 8 frame box. The boxes from Mannlake are wide enough to split it with a 3/4" thick divider board, incase that's where you got your boxes.
