My first solo cut out ... collected a few swarms and assisted whilst another beek did a cut out in a conservatory roof. That was very messy with runny honey everywhere .. we were both covered in honey and bees trying to clean it up. I was rather dreading what I would find as I knew they had been in there for some time. The fact that there had been a comb collapse obviously helped as it looks as though the space they had available was being used mainly for brood and not stores.
TBH I was rather grateful that there was not a lot of honey in there .. what little there was was in the top of the combs underneath the composter lid and stayed there when I cut the combs off. I left the remains of the combs in the bin lid on the ground in front of the hive when I had finished and over the afternoon they cleared every scrap of honey out of the comb.. When I went back to collect them in the evening there was not a drop of honey left .. amazing how quickly they can clean up when they need to.
Pretty easy job as you say. Good one to start on as very confidence building.
