Tar and bug remover for automobiles will break down the tar and make it easier to remove from the carpet fiber. WD-40 or waterless handcleaner (the type mechanics use) do essentially the same thing, however. After you have removed the tar, in either case you should use vinegar to neutralize the chemicals so that you don't create a mystery stain from the residues left that attract dust and dirt.
