I am going through this right now.. so wait for my full answer!
Go to Walmart, buy 5 boxes of MOTH BALLS get some old nylons or buy those little .33 cent onces they have on the rack/baskets. You will also need foil pie plates and duct tape Put some moth balls in the nylons and tie the ends.
Put the little nylon packages all around the shed and under anywhere that it is dark.. they hate the smell.
place moth balls in pie plate put another on top and duct tape the 2 together, poke holes in the pie plates and put them alll around your yard outside
contact a landscaping company if you are not a "do it yourselfer" tell them you want your yard airated ( they poke holes in the grass) and you want grub control put out.. Milky Spoor is a good alternative to chemicals if you can get it.
The skunks love grubs, and your lawn is probably full of them. Skunks HATE light, so if you have a high powered flash light or a light bulb on an extension cord put that under your deck for 6 to 10 days left ON..
Skunks hate moth balls. place them everywhere (my yard smells like my grandmas house but hey, the skunks hate it here now)..
Skunks are not aggressive, it takes alot to make one angry. If you opt for trapping, remember that if you have a trapper come onto the property the skunk is usually put down due to rabies. If you trap it you can release it onto the furthest point of your property or take it to a national forest... Make sure you cover the cage BEFORE you bait it. Have a Heart makes good cages.
