With the live traps, if you buy the plasticatch traps, they hold water and the skunk can be moved to the hydrant, if that is your forte. I shoot mine in coyote traps, but around the acreage, when we catch skunks it is with the plasticatch, and we carry them over to th garden hose, stand the trap on end and fill with water.
These traps are self contained units, skunks can be moved in them without them spraying, also skunk doesn't spray as you fill the trap with water. Would be handy in a city, shouldn't go to jail for drowning a skunk in the trap... key word "shouldn't".
