Ground Barriers for Burrowing Wildlife: Why Some Systems Fail and How to Get Effective Results
If you’re dealing with animals digging under decks, sheds, porches, or foundations, one of the first lines of defense you might hear about is installing ground fencing along the base of the structure. These systems are often marketed as “quick fixes” that are driven straight into the ground to stop animals like groundhogs, skunks, and raccoons from tunneling underneath.
Vertical barriers are not always the long-term solution people expect – and in many cases, they lead to repeat intrusions.
Why Vertical Barriers Often Fail
Animals that dig are extremely persistent and adaptable. When fencing is installed straight down into the ground, it only blocks the exact spot where it is placed. These critters quickly discover that they can start digging just beyond the barrier and tunnel underneath it.
Instead of stopping activity, vertical-only systems often shift the problem, which creates new burrows while leaving the original entry point vulnerable.
The Problem With Soil Conditions
Another major drawback with pound-in fencing systems is the ground itself. Many properties in Lancaster County have rocky soil, compacted clay, buried roots, or utility lines near foundations. In these conditions, driving fencing deep enough to be effective can range from extremely difficult to impossible and risky.
When barriers can’t reach the necessary depth, they provide even less protection for animals to dig under them.
Why Horizontal Protection Works Better
A more effective approach to wildlife exclusion combines both vertical and horizontal protection. Instead of placing fencing straight down, the material is bent outward in an L-shape underground. This creates a hidden barrier that animals hit when they try to tunnel – forcing them to give up rather than digging deeper.
This is the most effective method because critters naturally dig downward and forward. When they encounter solid material extending outward beneath the soil, they usually abandon the attempt.
Why Ground Barriers Must Be Customized
Every property is different. Soil composition, drainage patterns, landscaping, and the specific animal involved all affect which solution will work best. Installing the wrong system often leads to continued burrowing, shifting damage, and unnecessary repeat work.
A professional evaluation ensures the barrier is designed for your yard, not just installed along it.
Final Thoughts
Not all ground barriers are effective. Vertical-only fencing may provide short-term relief, but it rarely stops determined wildlife for good. A properly customized underground barrier that includes outward protection is far more reliable and prevents the cycle of re-entry that frustrates so many homeowners.
