Bifen IT will not treat for roundworms in a yard. We do apologize but we do not carry a product for the lawn that is labeled for roundworms and we are not aware of any products available that would take care of this issue. Generally it is necessary to take non chemical steps to treat this. Keeping dogs from a contaminated area for at least 1 year will prevent infestation and if that is not possible then removing and replacing the soil in area. Removing feces from the area as well when dropped is needed as well.
