throw cold water on it to scare it away

NO. They will get you befor the water gets them.
DO: Get a slender long shaped Box trap, with spring lid on the back end.
One they can"t back out of. Bate it with someting skunks only like.
DO: Put it beside the entrance to its home. It will smell the food and go inside to get the food, and not be able to back out as the lid will have snapped shut.
REASON? Slender long box? a skunk can only spray anyting or anyone if it can turn and flick it's tail over its back, and let it go. When it crawled into the long trap it could neither turn or back out, as the lid snaped shut.
