If you really don't want to use chemicals to remove moth eggs and larvae, you will need to completely clean the infested space from top to bottom. This can be difficult and is sometimes impossible. Moth eggs are very tiny and can be hard to find. You will also need to freeze all clothes and fabrics to kill any remaining eggs. Keep fabrics in the freezer for a minimum of 72 hours. This can be an arduous process! For this reason, many people prefer chemical treatments.
