What should you not put in a compost tumbler?
DON’T add meat scraps, bones, grease, whole eggs, or dairy products to the compost pile because they decompose slowly, cause odors, and can attract rodents. DON’T add pet feces or spent cat liter to the compost pile. DON’T add diseased plant material or weeds that have gone to seed. Citrus and pomegranates will attract rats. They will chew right through a heavy, plastic composter. Avocado pulp is OK, no peel or pits.Which compost ingredients attract rats? Any food scraps can potentially attract rats to compost bins. Cooked food, potato peels, egg shells and particularly pungent ingredients like meat, fish or dairy, however, are particularly appealing to rats and are most likely to attract them.
