It is 6 -8 inches long, short legged, blackish, heavy-bodied, with a long snout, short tail and broadened , shovel like front feet. The make subsurface tunnels, where a ridge of sod several inches wide is pushed up at least two inches.

These subsurface tunnels are divided into feeding and main tunnels. The feeding tunnel tend to meander or wind back and forth. They commonly dead-end. Feeding tunnels are created when searching for food and are rarely reused.

Main tunnels are usually straighter and connect other tunnels or mounds of loose soil. They are used daily by the moles to get from place to place. They also trap earthworms that enter the tunnels.

Control moles by setting traps across main tunnels. The harpoon trap is set by mashing a portion of the main tunnel and setting the trap across it so that the spring-loaded spikes are just penetrating the soil. As the mole comes through the tunnel and pushes up the soil and triggers the spring the trap is sprung and the mole is struck by the spikes
