Although they generally cost about twenty dollars more, they are guaranteed for life against rust and corrosion. Porches, mobile home and sheds can be protected from burrowing animals, like skunks, by constructing appropriate barriers. The best barricade consists of digging a one foot by one foot trench around the base of the structure. This type of barrier prevents animals from digging under the structure. No matter how far the animal digs it will keep meeting mesh.
Some people prefer to pour concrete reinforced with rerod.
An easier method consists of extending the walls of the structure so that they are flush with the soil. Obtain some heavy flat stone like patio block or slate and lay it on the surface of the soil around the base of the structure. This stone will act as the screen did in the previous method except it does so on the surface. The stone forces the skunk or woodchuck to start digging farther away. Since animals, like us, take the path of least resistance, they will most likely decide that your neighbor's shed is a more convenient place to live.
