I need some help with frost inside my hive. I tried searching google, this forum and other forums, cant seem to find anything concerning frost inside hives. I have 1 hive located in Western MA, which is "winterized". It's has 3 deeps and a medium on top. This is my first winter so i opted to not harvest any honey. All frames were pretty solid with honey going into winter. Been below freezing since November, recently reaching -30 at night in past weeks.
Today temps finally rose above freezing closing in on 50 so decided to take a peek. First thing I noticed was the mouse guard blocked with dead bees so I took it off. Behind the mouse guard was a packed layer of dead bees so I began scooping them out. Looking inside I could see the bottom board was completely packed with dead bees so i decided to lift the hive body and put it on a clean bottom board. Before I did this I lifted the top and found the inside walls of the top medium to have a layer of frost reaching the closest frames on both sides. The inner cover is also frosted over. Huge die off but still have large cluster in the top deep box. When I moved the hive body to a new bottom board the hive is heavy so I believe there to be a good amount of honey still in there.
So despite my attempt at winterizing there's a ton of moisture trapped inside the hive for some reason. I think the -30 temps, die off and mouse guard blocked any air flow into the hive. I'm just trying to figure out what I should do at this point on. I have plenty more hive boxes. I was thinking i should transfer the bees and frames into new hive boxes. Tomorrow and Tuesday supposed to be in mid 50's.
So anybody deal with frost? Should I disturb the hive and put the frames into fresh boxes?
