Little black flying insects have taken up residence in our Sealand toilet/holding tank. They come flying out when flushing. Any recommendations on how to get rid of these buggers? Thanks.

Open valve, spray your favorite aerosol bug killer into the tank for 5~10 seconds. Close valve and let sit.

Then I’d fill completely and flush...twice. Completely.

I did fill the blackwater tank completely full once and flushed. Didn't do the job. I'll try it again and spray raid or something into the tank. Thanks.

Some tanks, like mine, have an area in them that never gets flooded even when full. It can be a high spot in a corner caused by the top of the tank sagging slightly. On mine, they chose to put the "full" sensor in one of those corners so my tank level gauge will never read "full". The little bugs probably concentrate in a spot like that.

Do you leave your black tank flush valve open when hooked to campsite services?

You can fill the tank all you want but they will retreat to the vent pipe until the water subsides. They are in every sewer system, even your s&b home. Worse when a septic system or in your case a holding tank is their abode. I get a few sometimes.

A good dose of bleach works.
