What causes the “tennis ball” size holes and piles of dirt in the lawns and landscape around our commercial buildings and perimeter embankments?
A. Two major rodent pests are usually the cause. These are gophers and ground squirrels. Gophers leave piles of dirt but the hole is usually closed. Ground squirrels also leave piles of dirt but he hole is always open. Both of these rodents are very destructive to landscapes and can end up causing expensive erosion and structural problems. The professional materials used for control require an Ag. Applicators license.
