Moles

Moles are carnirvores that make themselves at home in lawns rich in grubs and insects. When their food is seasoned with castor oil, they will go elsewhere for meals. (Wouldn't you?) Mix up a spray of 3 parts castor oil to 1 part dish detergent; use 4 tablespoons of this concoction in a gallon of water, and soak the tunnels and the entrances. Check out your soil for the presence of pests; if you have a lot of moles, you probably have an oversupply of grubs and bugs.
