For me the 2 door trap works good. Has one on each end. I spray the trap with baking soda mixed up in water. I imagine scent killer would work. Apples, apple juice poured on ground, brussel sprouts, lettuce, spinach and about anything that is still green in the garden works in the winter. If he wont go in with the scent removed. Might try running sticks or brush on it. I have to do that sometimes to catch fox.
Good luck.
