put a large black trash bag over your live catch trap... just leave the entrance open... after you catch the little stinker pull the bag closed over the end... gently move him to the rear of your car, place the opening around the exhaust pipe and fire that mother up... make a small slit in the bottom of the bag to release the build up of gasses but in 15 minutes it's all over... no smell, problem's solved... everyones happy but Peppe...
