Good morning. When you set the conibear take sticks and run them through the jaws and into the bottom of the hole. Bend the trigger wires so they are about 3" apart and place the sticks so they just miss touching the trigger wires. Narrowing down the opening will make the mink hit those wires and bingo mink will be there in the morning. Don't worry about your sent they don't seem to mind. If they're eating fish squirt some salmon oil or use sardines (in oil)l in the hole. They are used to squeezing into tight places. My biggest so far nose to tip of tail is 26" I'm in Michigan and he was a pure wild mink.
