Let the spot rest for a couple weeks and really get at it the last week of the season. Im assuming your season ends at the end of Feb.? Let the trap sit in boiling water mixed with baking soda. Make sure all of your clothes & gloves are washed and free of foreign odors. Spray your trap down with Scent Killer and leave it in a plastic zip-lock bag. Try a dirt hole set 10 yards away from the den with some fox urine scent. If you can finda spot they like to use going into the den a snaremight be a good choice.
