Nibor D can be used down the toilet and drains. It is recommended to treat all plumbing within the home so that it evenly disperses the product in the septic tank. Nisus advises to use about 5 scoops of the Nibor D in a gallon of water, pour ½ gallon of mixed solution per toilet and flush. For drains, use 1/3rd gallon per drain. Reapply after 2 weeks depending on the severity of the infestation. View the product label for more information.
