Skunks are common backyard visitors, and many homeowners are concerned about their presence and potential property damage. Understanding their navigation helps in keeping them out. This article explores skunk physical abilities, their interactions with fences, and practical deterrence strategies.
Skunk Physical Capabilities
While not known for jumping high, skunks can jump about three feet. Skunks are poor climbers compared to raccoons or cats. Their climbing ability varies by species; the common striped skunk struggles to climb structures over 1.5 to 2 feet. Spotted skunks are agile climbers, capable of scaling fences up to 6 feet high and even trees over 20 feet.
Despite limited jumping and climbing, skunks are skilled diggers. Their sharp claws make digging their primary method for bypassing barriers and accessing areas. Skunks can dig under fences, creating holes as small as four inches wide to squeeze through. They can dig tunnels up to two feet deep. This digging behavior often relates to their search for food, such as grubs, or to create dens for shelter.
Fence Design for Skunk Exclusion
To prevent skunks from entering a fenced area, the design must address their digging habits.
Burying Wire Mesh
Burying wire mesh, such as hardware cloth or chicken wire, beneath the fence line deters skunks. This mesh should be buried 6 to 12 inches deep. Use 1/2-inch or 1-inch hardware cloth to prevent skunks and other small animals from squeezing through.
L-Shape Barrier
For enhanced effectiveness, bend the buried mesh outwards in an L-shape at a 90-degree angle, extending 12 to 24 inches away from the fence base. This creates a horizontal deterrent skunks encounter when attempting to dig.
While digging prevention is primary, fence height remains a consideration, especially for agile spotted skunks. A fence height of 2 to 3 feet deters striped skunks, as they do not jump or climb high. For properties with spotted skunks, a fence of 6 feet or more, particularly one with a smooth surface, makes climbing more challenging. Beyond perimeter fencing, seal off accessible spaces beneath structures like decks, porches, and sheds using buried wire mesh or other sturdy barriers.
Additional Skunk Deterrence Methods
Beyond physical barriers, several strategies make a property less appealing to skunks. Removing readily available food sources is a primary deterrent, as skunks are opportunistic feeders. Secure trash cans with tight-fitting lids, remove pet food left outdoors, and regularly clean up fallen fruits from trees. Ensure compost piles are well-managed and inaccessible to reduce attractants.
Eliminating potential den sites further discourages skunks from settling. Clear away woodpiles, dense shrubbery, and debris that could provide shelter. Motion-activated lights can startle nocturnal skunks, making them less comfortable. Strong scents like citrus peels, cayenne pepper, or castor oil also deter skunks, though their effectiveness varies and requires frequent reapplication, especially after rain. Addressing grub infestations in lawns removes a significant food source that encourages skunks to dig.
