Eeew! Gnats coming from black tank??
I know I saw posts about this in the past but my search here is turning up nothing. Today we have little gnat thingies coming out of the potty from the black tank. What to do? Hate bugs especially in...

I wouldn't think a whole can of insecticide is necessary. A couple of small bursts of spray in my garage kills everything. The black tank is very small, in comparison. If it was me, I'd throw a cup of diluted bleach in the drained tank and not use the toilet for a couple of hours.
These are not gnats. Sewer flies are very determined. They thrive in sewers! A couple of squirts won't do it. The idea is to fumigate/engulf the whole tank including the piping and crevices of the toilet.
Use the whole can,there's no need to save any.
