My last two wooden brood boxes that I’d put aside to repair — for the last few years they’ve been home to a colony that swarmed into them when they were stacked up full of frames that I was intending to chop up for kindling.
I don’t think there’s anything I can do with them though. There’s so much damage that even if I broke them up I don’t think there’d be enough parts to reassemble into a single box.
