My wife has bought 250 bee boxes with frames; about a third of them have drawn comb and some honey. They will be stored in a tent like structure on top of pallets. So they will be dry but subject to the cold of a Manitoba winter. The average low in December, January, February is below -20 degrees Celsius (-10 degrees Fahrenheit). We will probably try to get a few of them started in the spring. What I am wondering is that if there are any hidden diseases in the boxes will the cold kill them off.
