This is a very effective way of ridding your yard of gophers, moles, voles and other destructive, burrowing root-eaters. 'Chase' uses a natural plant extract -- castor oil -- to give the soil a bad taste and "chase" burrowing animals from your lawn and landscape. 'Chase' is available as a ready-to-use liquid hose-end spray or as dry granules for broadcasting with a lawn spreader. Water in thoroughly after application to move the castor oil down into the soil. Liquid covers up to 10,000 sq. ft. Granules cover up to 6,000 sq. ft.
