There could be a few reasons why your compost pile is not heating up. It could be that your pile is too small, too dry, or lacks enough nitrogen-rich materials. Try adding more green materials like grass clippings and kitchen scraps to increase the nitrogen content, make sure the pile is moist but not too wet, and consider adding more bulkier brown materials like leaves and shredded paper to increase the size of the pile.

A bad smell coming from your compost pile could be a sign that it is too wet or has too much nitrogen-rich material. To fix this problem, add more brown materials like leaves or shredded paper to balance out the nitrogen. You may also want to turn the pile more frequently to increase airflow and reduce moisture.

Pests like fruit flies, ants, and rodents can be attracted to your compost pile if it has too many food scraps or is not covered. To prevent pests, make sure you bury your food scraps deep in the pile and cover them with a layer of brown materials. You can also try using a compost bin with a lid to keep pests out.
