Flies
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...

We once had the flies in the black tank. Shut off the water and sprayed a generous quantity of Raid down the toilet. Closed the lid. Flies gone and never came back.
