Re: Bear (electric fence?)
We had this happen a few years ago. our incident occurred in the fall. After the first incident we clean up, the bear came back 3 days later for another snack, that was when we put up the fence.
We set up an electric fence using your typical/average livestock fence. We put 5 rows of wire, 5 feet high in total. Because it was a short run of wire, compared to the typical several thousand feet of cow fence, when we tested it we got about 9000 volts, more than enough to stop a bear. Someone told us that if you really want to stop the bear in his tracks, you put some sheets of steel or galvanized roofing down just on the outside of the fence, that way the bear has all 4 paws well and truly grounded when he touches the fence.
We later switch to the same solar charger that Huck mentioned from Parmak. Testing still showed 8 to 9000 volts, again very small containment area. We have never had another incident with the bears, but I cannot say if that is because of the fence or because he learn his lesson. Regardless, the fence will stay in place just in case.
