AHA...I began searching for optimum heights for my hot wire to keep predators out. I do have the heights adjusted correctly, however, there is no one-size-fits all, when it comes to height. A regular sized raccoon should be stopped at a height of 8-9 inches from the ground, but an overly large one, may be able to easily get over it. Moving the wire high enough to stop the one larger raccoon, can result in it being ineffective on the normal sized ones. (Yes, I have 2 strands, one is about 3.5 inches from the ground, the other is 9 inches from the ground) So what to do?
Baiting. The instructions that came with my fencer, about baiting, were for keeping horses, and cows in, so I didn't pay much attention to it. After doing some research, it's also the best option for teaching predators to stay out. Tomorrow I will be making a few small tinfoil "cups/open pouches", and putting some cat food (small pieces of hot dog work too) in them, then wrapping the top onto the fence wire, to hold them. The bait attracts the predators, and ensures their efforts are focused where they will get jolted. That way you don't have to keep adjusting the fence height. One person said they did this for about 10 days. At first, they had to replace the bait every evening, and it would be gone by morning. By the end of 10 days, they were having to empty the bait, because nothing was touching it. I have a plan now.
