The active ingredient in Dr. T's Whole Control Mole Repellent is castor oil. Castor oil coats the animals' food source (roots, grubs and mole crickets) and causes stomach disruptions in the animals. After repeated exposure, the moles will avoid the treated area. Dr. T’s Whole Control Mole Repellent does not contain any type of rodenticide that will harm cats or kill tree squirrels.
