My family had skunks under our house last year, and we we were actually "skunked out" about 5 times. We used the Have a heart and we did have to shoot them, even if you cover the cage with black plastic, they get startled and still spray, and very sadly, they spray when they are shot. Shooting was a very last resort, but there was nothing else we could do. I had to send my two children, one of which was just born, to my parents house for a couple of days because the smell was so bad. There really wasn't much we could do about the smell, just open windows, burn inscence, or oils, anything and give it some time.
