Charles from Pine River, Mn writes
Septic guy says we must pump out immediately after demand CS was poured down bathtub drain to kill bugs? says pesticides will kill bacteria in tank and harm the system?
Per the Demand CS label: Do not apply directly to sewers or drains, or to any area like a gutter where drainage to sewers, storm drains, water bodies, or aquatic habitat can occur, except as directed by this label. Demand CS cannot be used in a septic system nor can any other insecticide we carry be used down drains.
