Anyway you catch them regardless of the method requires euthanizing or sedating the skunk to extract the essence. So once you catch it how are you going to dispatch it to drain the essence. Most methods of dispatch will cause the skunk to spray. You can get lucky at times with a fast kill with a conibear.But that isnt any guarantee either it will be odor proof.

The only fool proof method is chemical uthanazia/sedation done properly. Not knowing your age or experience that one little issue may be challenging for you.
