Rookie mistake. I put an entrance reducer in the front but left a large enough space in the roof for mice to get into the hive. Didn’t check on the hive for several months, thinking I was supposed to leave them alone through the winter. Today, I found that the mice had killed/eaten every bee and much of the comb. Arrgh.
The hive stinks of mouse urine and droppings. My question is if the remaining comb can be used by a new package/nucleus in the spring? Do I need to start completely from scratch?
