We're having a problem with flies i.e. fruit and sewer flies. Can't seem to get rid of them in our travel trailer. We've flushed and cleaned out the grey water pipes/holding tanks and all other drains...
The larvae live in the gunk on the pipes. In my case they were coming up from the shower drain and I have successfully used boiling water poured down the drain to get rid of them. Last summer they appeared and I had to use the boilng water twice to get rid of them.
Once I had them in the black tank. I sprayed a bunch of insecticide in it through the toilet and that killed them.
