Well this is my first year using them, usually I just live trap, but I havent had any luck, the only thing thats been eating and getting in my traps are mole/mice things, not a field mouse or a ground mole, but some kind of hybrid mole/mouse, lol... If I get a chance I will take a pic of one... But I've used fish oils, corn, dog food and marshmellows... And your also suppose to use a lure by the traps, which I havent done yet either, been busy catching them in live traps and yote hunting to bother with them this year and theres always next year!
