I have a couple of beginner's winterizing questions.
This may be kind of silly, but I'm supposed to remove my Apistan strips in the next week or so.
You can open hive and take strips away. It depends what to do how calm your bees are. Cold is cood, because they do not have time to defence.
Do I need to worry about chilling the hive
Dont worry
Second question, my hive is now two years old. Do I need to requeen in the spring?
Queen lives 3-5 year. Bees requeen hive themselves if it is necessary. It is nothing to do with wintering. I change every year queens because one year old lay eggs better and it does not swarm so easy like 2 yeard old.
If you have winter food enough, there is no use to disturp or open the hive during winter. There is nothing to be done.
