Mole Scram works by combining taste that moles dislike as well as a strong odor that is very mild to people but offensive to moles. Our mole repellent does not kill or harm moles, it simply drives them away so that they will do no farther damage to your property. Mole Scram is all-natural, organic, and fully biodegradable. Mole Scram is used as a spreadable repellent -- applied across your landscape, yard and gardens -- and is not water-soluble. Long-lasting Mole Scram will keep moles out of your yard because it coats the worms, grubs and other insects moles eat with the disagreeable flavor of castor oil. Mole Scram changes Mole behavior. Coverage = 7,500 square feet.
