Not much time spent, and anything living in that tank is now formerly living, so smells are not an issue for the rest of the year.

Maybe, it depends on which toilet you have… there is a large chamber in the commode itself where things can live… you would have to fill the tank until the water just about to overflow the top of the toilet at the seat level to kill those buggers that way…

Unlike a home toilet there is the inner bowl with the dump (blade or ball) valve, and a outer bowl where it is connected to the floor…

Has anybody mentioned plugging the roof vent when you spray the aerosol? Remember, those vents and pipes are a great place for them to put eggs on. I'd shoot some down the vents, too, then wrap them with something to help keep the air mixture in there.

OP - are you leaving your black tank valve open?

Get wasps in my home bathroom too. That's scary when you taking a shower.( If you get what I mean.:E) They are easy to kill with a shot of insecticide. If they land I can get them with a fly swatter too. They come in from my attic.

Most likely your toilet is not seal properly. You have a dry trap or a broken pipe. These flies live in the sewer lines but cannot escape unless there is a breech in the pipe.

Well, there definitely isn't any water leaks. The toilet is on the second floor and you would quickly know if there was. They seem to live in the toilet bowl itself. Maybe it's a different bug.

It's possible for their to be a breach without water coming out.
If there is a leak at the top of the pipe or joint flies could escape however there would be no leak. Water could pass at the bottom of the pipe. The pipe would not leak unless it were flooded.(totally full of water)

This is true. Are you a plumber, also?

Yes, well not officially but I have a lots of experience in the plumbing business.

When we bought our used rv we had the same problem I poured a half gallon of full strength bleach in the tank and let it sit over night. Have not had the problem again. Our tank was empty when I out the bleach in.
