I wonder if anyone has ever tried something similar for moles? Perhaps a neon transformer and a couple probes? :ashamed:
You don't need to take it that far for moles. Moles hunt worms by sound believe it or not. So they are extremely sensitive to annoying sounds and vibrations. I had a mole problem and installed some of those stakes with batteries and a little vibrating cell that vibrated for a few seconds every minute or so. Worked like a charm. Gophers are different, they are eating roots, not worms. But for gophers, I spread cayenne pepper on the lawn and water it in, then keep the kids and dogs off of it for a few days. The pepper gets in the gophers eyes so they leave and go bother my neighbors.
My Dad had an idea years ago of using a car battery, a distributor, coil and a hand crank as a worm extractor. The crank was just to turn the distributor shaft to make the points open and close, which then went through the coil to boost the voltage going into the ground. All of the spark plug wires would be joined and going into the ground, along with the negative terminal of the battery. Turn the crank a few times and they should come crawling out. it should be much safer than using line voltage, plus it would be portable so we could use it AFTER we got to where we were going to fish. We never got a chance to try it though before he passed away. If anyone tries it, let me know if it works.
