I have been offered a large building in which to winter my bees. The building was, for years, used to store potatoes. We are talking about a large commercial potatoe operation. My question is this - Are there any risidual molds, funguses, etc. that might make this a bad building to use to overwinter bees. Eric Abell Gibbons, Alberta Canada (403) 998 3143 [log in to unmask]
