Green cone basics Trouble shooting green cone problems Odors can be controlled by removing excess or inappropriate waste and providing adequate fresh bedding. Adding a thin layer of leaves or dried grass to Green Cones will reduce odors. Never add cheese or other animal products in any type to compost systems. Fruit flies are more of a nuisance than a serious problem. Minimize fruit flies in a green cone by adding a thin layer of leaves or sawdust.
Rodents can be a problem.
The easiest way to keep animals from entering a Green Cone is to keep the lid shut and meat wastes out. The underground basket from a Green Cone may be covered with wire mesh hardware cloth to prevent pests from entering. James A. Kropf, Extension Faculty, Horticulture, Small Farms and Farm Marketing.
