Roebic K - 77 Root Killer will not kill or prevent roots outside of the drain field or pipes but will kill roots that are already invading the drainage system of drain fields. These crystals are applied by pouring them directly into the toilet or directly to the septic tank drain field through the distribution box. This will work to clear roots from leach and drain fields to improve the flow of the drainage system and works year round without harming surrounding trees or ground cover.
