I have a mole problem in my yard and my thought is these ground burring creatures must have some trait that would allow me to detect them while making tunnels in my yard. My thought is that if there were some type equipment (similar to a metal detector or something) that I could scan my yard with and detect what ever sound or wave or frequency that these critters put out, I could catch them and put them in the relocation program. Anyone hear have any thoughts that may lead me to the equipment that could possibly accomplish this task? Thanks in advance for any ideas Jack
