My question as a new beek is two part or more. I have a lot of ants where I want to put my hives, at a seminar I talked to the pro and he said to put my hives as close to the ground as I could. I am in zone 7a by USDA, he was fearful of the cold. My question is could I put my hives on a short stand with legs into a container and maybe put oil into them forming a moat to keep the ants out? Or will any rise contribute to the freezing of hive. I see others in the area raised, all options are welcome.
