Hi both my hives are now on wooden stands that sit on top of 4 concrete pavers each. I was wondering will the larva fall on them and work their way to the ground. Im pretty sure one hive is lost to SHB it was a new nuc alil over a month ago and isn't looking good. But I still want to try and prevent the problem from happening again. I thought of jus putting a square cooking tin foil thing under them with water or mineral oil or what not under them since I do have screened bottom boards. Any help will be appreciated!!!!
