EFB in my hives changed everything and I spent the remainder of 2010 trying to limit the spread from one hive to another.
2011 started with me still boiling up brood frames. I wanted to finish the brood frames before I started on the super frames. It took me months to clean up the allotment entirely - that meant boiling all of the spare frames in boiling water with soda crystals. And scorching the boxes, floors, and crown boards before moving them and the bees off the site altogether.
The allotment feels quite lonely without the bees now.
