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.
Got to kill the eggs/larvae that are on toilet pipe, under toilet, top of tank. the sewer flies die off pretty easily it's their brood and future offspring that are tough.
