Anyone here had experience getting rid of a skunk visitor?

3. They usually only spray

in response to threat from a predator or in a territorial dispute.
Are there dogs around?
Should you try to trap it, you'll likely go a few rounds first with raccoon or possum first, pending your region.
Skunks are quite shy, retiring and rarely bothersome. With few enemies, they pretty much go where they want. Light and noise will often keep them away.
Have you seen it? Or just smelled it?
If you can spot it, you might try a slingshot, or pellet gun to scare in away from your home.
As the scent carries quite far, it might be anywhere.
If spraying is a regular occurrence, it's likely a territory issue between rivals. Mating season is generally around February here in the Southeast.
I've used commercial repellents with limited success, but reducing the local population will indeed do the job. Trapping is not difficult, should you want to try it I'll tell you of my experiences.
