Don't bother with those silly step-on style traps, and the spike spring versions. I've tried them all, and this one is the only one you need. It's built like a tank, and caught 5 moles last summer. Youtube is full of good video's on how to properly place and set these, so once you know how to place, it's only a matter of time. Just keep out of reach from kids, or it will do some major damage. Be sure to buy at least 3 or 4 of these, as my trick to catching moles, was having enough to keep setting in new activity areas. They move often, so don't think you'll set one and get them.  Adios moles!
