To repel moths, put some cloves in a sachet bag and place it in your closet or dresser drawers. You can also use cedarwood, lavender and rosemary or cedarwood, lavender and camphor essential oils to repel moths. Put a few drops of each of these oils on a cotton ball and put it in drawers or hang it in the closet.
Moths also dislike dried lemon peels.
When ants are a problem, check in your kitchen for ingredients. Ants will not cross a line of cayenne pepper. Ants also do not like cream of tartar, dried peppermint, cinnamon, salt, dried sage, lemon juice or cucumber peelings. Soak cotton balls in the mixture and place them in locations where ants are found. They eat it and take it back to the nest.
