The holes are around 3 - 4 inches in diameter and and 3 - 4 inches deep. I didn't have this problem before the installation of the sprinkler system. The digging is isolated to where the soil was disturbed during the installation of the irrigation system.
There may indeed be a way to stop the digging but first you need to identify the animal in question. You may need to make a late night excursion outside with a flashlight and try to catch the culprit in action. You can also call in a professional company for a free estimate and they may be able to identify the animal by the type of damage it is leaving behind.
