Nearly every night we find these tiny moths in our shower recess. There is only ever one.

I’ve never seen one this small before. No idea where they’re coming from or how they get in.

Today I found one in the laundry (this one).

Only that it relates to things that flutter by.

We never see them flutter by, only resting on the tiles.

I guess it's a high speed flutter, then. More of a flit.

Drain flies ? … come up thru the floor waste in the shower … been having a similar issue … but only appear after shower has been on for 30sec or so … and there’s always more than one in our case … many more [bigsad]

Kev, I thought you'd abandoned us. Good to see you here.

I know it is not the study of leopards. I think that butterfly collectors just gave it the name to make it sound more exciting.

I doubt they would get past the trap in the drain?

Snakes and frogs do,but an insect like a moth?

Drain fly. Larvae lives in the traps and pipes. Sometimes called sewer flies or sludge flies. Years and years ago, I lived in a small cottage with an old waste system. Plagued by them coming in up through the pipes into the separate wash house and bath tub as it was very close to the waste tank. Problem abated when the septic tank was cleaned out.

Thanks Ian.

…yes, I’ve gone to the Isuzu dark side (x2) … but I’m still a Land Rover tragic at heart [bighmmm]

Yep. That’s them. We are sewered. I believe they actually traverse the water in the s-bend (more prolific when it’s hot water going down the shower drain). We have sprayed the shower drain & bathroom floor drain (numerous times) and nothing flies out trying to escape the spraying … then next time we shower there’s 10-30 of the effers alighting on the white tiled walls of the shower recess … they HAVE to be living on the sewer side of the s-bend ?? We’ve used boiling water, vinegar, baking soda, chemicals … but they eventually come back … went to Europe aug/sep for 4 weeks so the shower wasn’t used for that time …. They reappeared about 3-4 weeks after we returned and started using the shower again … :bat:

Google drain flies Ron and all will be revealed

By gum, I believe you blokes are correct. I’d never heard of drain flies before.

Thank you.

Nor had I Ron, I've heard of bar flies though.

An update on this.

We noticed tiny black worms, 10mm long x 0.25mm diameter, in the floor tile grout grooves in one corner of the shower recess, well away from the drain. Google showed them to probably be drain fly larvae.

I pulled the shower grate out and cleaned out the 15 years of accumulated sludge. I also gave the drain two doses of salt, baking sofa, and white vinegar.

I’ll do a bio-enzyme cleanse, too.

Thus far, no more drain flies or worms have been seen but I’m not convinced I’ve killed them all.

You do realise that the County and the Perentie use the ISUZU Engine, of which is in my Perentie:TakeABow:

I do Baz. The Isuzu 4JJ1 engine was the lure. My D-Max is 18yrs now. Drive it. Service it. Never let me down, so when the MUX came up for a cheap price it was a no brainer … threw 28k at it and turned it into our daily drive/ tourer/tow vehicle. Very happy with it.

Fluids you could stretch the truth and get "Land Rover Powered" stickers for them. The various D-max versions used in the "All 4 Adventure" TV show are impressive, especially the one they drowned and revived.

So salty sodium acetate? What is/was that going to do?

I'd be giving the drain a decent dose of sodium hydroxide or drain-o. For drains used extensively by women, after a flush I'll follow up with an entire can of Veet. Stinks to buggery but completely breaks up any trapped hair (which insects love to breed in).
