Here is a good publication put out by the Alabama Extension Service detailing how to deal with moles...I personally like the "harpoon" traps and you see these type traps much more often at hardware stores. Don't look at this as a chore but something to have a little fun with b/c it's not a quick process. My best advice when it comes to trapping is to "walk down" as many tunnels as you can as often as you can and see if any of the same ones keep coming back....if so they will be the "travel" tunnels to and from bedding and feeding and the easiest to trap them in....many time they tend to bed around tree stumps, especially ones that are rotting out after being cut....hope this helps....
