We find where the moles and gophers are tunneling and insert a baited worm. When they eat it, it kills them. Unfortunately for us, moles can sometimes store their food, including the baited worm, to eat later in the winter. Unfortunately for them, when they finally feast on their food storage in the winter and eat the baited worm, they never see the light of day again… which really for moles probably isn’t so bad since they can’t really see in the day time anyway. Either way, they’re dead after eating it.
