Hey, Ace - sorry to hear about the hive loss. I'm not clear on a couple of things that you say here though:
When you say varroa frass in the lower boxes, do you mean those crystal deposits in the cells?
"there was quite a bit of honey but it was all over for the majority of the frames. " not sure what you mean here
"Two or three frames were solid in each box but all on one side." I'm guessing you mean solid with capped stores... If so, that really is weird - they ate the stores on one side between two frames but not the other, and seemingly moved around the hive to do so???
With my two hive varroa wipeout last year there was barely a dead bee left in either hive - they all just left over time.
