Need Pocket Gopher Device

I have a need for an electronic device that would kill Pocket Gophers. I know there has been some talk on the board about electrocuting rats in a garden. But this is different.

The idea came about after seeing a taser gun. I know that a high voltage device is just to immobilize and disable a person. But if the correct amp applied to the device, a gopher could be killed.

I'm not an electrical person. But I am familiar with pocket gophers, their habits and tendancies. I've inventing a "calling" sound that pocket gophers find irresitable. They come up to investigate the sound. I want to place the electrical trap inside their hole and "call" them to it with a sound. But I don't know how to do the electrical part, so I'm looking for guidance on this.

My email is kevolson56@hotmail.com if someone is interested in helping me develop such an invention.

Thanks
Kevin
