is this useful for red ants found in garden?
Thanks for your interest.
DE’s minerals are great for the yard and gardens.
Apply DE to ant hills. Small ants, regardless of color, may require a few applications to completely eliminate them, as they burrow new hills elsewhere, after we cover their initial hill with DE, but if we keep at it, eventually they disappear. Big ants are eliminated within two applications of a reasonable amount of DE applied to their ant hill. Ants in trash cans can be controlled by either painting DE around the bottom of the trash can or sprinkling it dry around it. They'll go elsewhere, as they do not like walking over DE. Of course, you will need to find their home to completely eliminate them, but it will keep them away from areas you put DE. Sprinkled around the house foundation keeps new crawling insects from coming inside.
Fire ants will need regular application of DE to eliminate them, but if you continue regular applications, it will eliminate the fire ants.
