Here in NJ we have a huge bear problem. In the last 3 days I've seen 6 differant bears and my wife seen 2 more that I didn't see and thats just on my farm between my sawmill and my house. yesterday I had a bear in my sawmill building. He just tipped over the garbage cans I'm really surprized he didn't get into the refrigerator. Anyway my beehive is at the sawmill. It's out in the log yard between some piles of logs. So since the bears are prowling around I put up an electric fence around the hive. I bought a solar powered one that is good for 2 miles of fence. I made a 20x20' square with the hive in the middle along with the fence box and ran 3 strands of wire. One about 10" off the ground the next about 18"and the last about 30 " high. Did anyone else fence there hives in? How did you do it? how many strands of wire and at what spacing did you use? I'm thinking of running a 4th strand just to make myself feel better.
