I do not want to hurt septic system by using something around the drain that will work its way into tank.
The Gentrol Aerosol can be applied to the sides of drain pipes where scum collects and provides an area for insects like drain flies to breed. We don't see any harm in it being used in the pipes of a septic plumbing system, but if you are still unsure that you can use it, you can contact Zoecon the manufacturer for further information.
