Safe home remedies for getting rid of ants include cayenne pepper, citrus spray and grits. Sprinkle cayenne pepper liberally where ants enter. Use black pepper or cinnamon the same way. Mix citrus peelings and water in a blender or food processor. Use lemon peels for best results.
Pour the mixture into a spray bottle and spray anywhere ants are seen or have been seen. Scatter instant grits along the path of the ants. The grits serve as a dehydrator when the ants ingest it. It absorbs all the water in the ants' bodies, causing death. Other effective repellents are tea tree oil and cream of tartar.
