"In 2002 at Greenville Spartanburg International Airport, we started to get areas in our perimeter fence where coyotes and other wildlife were digging under the chain link fence. To prevent this, we began by filing the holes in with soil, but the wildlife were able to re-dig the holes. Then, we tried using rip rap stone which worked better at keeping wildlife out, but it created maintenance issues. During mowing operations, the mowers would hit and move the stones, and the stones made trimming the fence line with weedeaters much more difficult and time consuming. Finally, we implemented Dig Defence in the areas where wildlife were digging holes, and we experienced great success in maintaining the security of our perimeter fence, as well as easier maintenance with mowers and trimming."
