The skunk waddling across your yard at night is a pacifist who really just wants to eat your pests.
Skunks are grub specialists. They go for the larvae of Japanese beetles and June beetles, the same grubs that kill grass from the roots up, and they'll dig up a yellowjacket nest and eat the whole thing too. Those little cone-shaped holes in your lawn aren't vandalism. They're a skunk telling you that you had a grub problem, and that it's handling it.
And the spray? It's a last resort, and they really don't want to use it. A skunk is slow, near-sighted, and mild-mannered, and before it ever sprays it will warn you over and over: stomping its front feet, hissing, arching its back, lifting its tail, even making little fake charges. It's an animal begging you to just back away.
So if you see one trundling through your yard at dusk, you don't have a problem, you have a slow, gentle, near-blind exterminator doing a lap of your yard. Give it space and let it work.
