This is my first year as a beekeeper and last week I noticed varroa mites on some bees. I collected about a hundred or so bees in a jar and alchohled them. I found 5 mites, I do not know if my problem is serious or not but winter is coming, my hive did very well this year and is good and strong but I dont want to lose my hive to the varroa over winter. I would like to get by without chemicals to control the mites if I can, and I understand that the mites will never be gone for good but I want to do everything I can for my hive. Any suggestions?
