Most of this digging activity is done at night and early morning. The dirt piles of the material were made at intervals of about 100 or more feet apart. The piles averaged about 6 to 10 inches high. The tunnel can easily be traced by these mounds of earth. When the mole is traveling to new feeding grounds his tunneling is just rapid. No speed on succulent roots.
Many moles were still alive when I took them from the traps. They have tiny pinkish sized white eyes. They are game little fighters and make a chattering squeaking voice when irritated. They leap out at you several inches and open their mouths widely trying to catch you with their long sharp teeth. They are capable of inflicting a deep bite and will hang on like a bull dog as I learned on several occasions. Their vision is very poor but their sense of smell keen. If left alone they will travel slowly on the surface or immediately start digging. The tunnels usually run about six inches to a foot or more below the surface. They have numerous side tunnels which charge off the main trunk.
The golden mole takes much of the blame for the damage done by the moles. It is an insect eater and does not eat vegetation.
