In recent years companies have been offering ventilation systems atop the hives to help keep the hives cooler during the heat of the summer. I have found another solution in my climate. Locate the hives so they have shade during the hottest hours of the afternoon. These yards consistently yield more honey. Also, I use deeps only and lifting honey filled hives and carrying them to the truck is tiresome. Try also locating the hives near a year-round accessable road. And finally, I have lost hives that were in the way of flash floods that are rare but will cause damage. High and dry is another location factor. Regards, Rick
