Every October skunks dig in our yard (we don't treat our lawn for grubs). I found a pesky skunk had moved in under the wood pile in my lean-to where my daughter parks. Despite seeing where it slipped between the wood and the wall and seeing blood, I could not find the skunk. Fast forward a month. Depending on the direction of the wind, there was still a very strong odor. Today, I moved enough wood to remove a pallet and found the skunk. It was really dried out but it still had a strong odor. Next year I will be sure to stack enough wood to cover all of the slats in the pallets. I use boards to cover the front openings.
