Indoor plant flies

[roughedges]

Hi MNs

I have lots of indoor plants and have done for years but for the first time, I am struggling with flies and worms!

The flies are incessant - I feel like I have tried everything- cinnamon, upside down matchsticks, watering only from the bottom, fly tape, a bug zapper - but they are still very much here!

My fig tree in in a large pot and every time I water it, small worms start jumping out - it is so strange. We find them shrivelled up the next morning on the floor if we haven't managed to rescue them. It's a bit grim!

Any tips would be welcomed!
Thank you very much!

I have loads of indoor plants and not aware of flies?!

@Iwillpassthanks they are tiny fungus gnats apparently!

I'm struggling with flies too op, not the worms though. It's only this year that I've had them and no idea why!

@Teapleasebobb ditto! So strange - wonder if it might be something to do with the wet summer?

Fungus gnats - they are hatching out from larvae in the soil. Take any affected plants, remove as much soil as you can, and any translucent larvae. Repot in fresh soil, cover with a layer of grit to deter the females from laying.

Worms - I think we need some pictures and measurements

I did read that I could be watering too much, but I've cut down on how much I water and they're still there, can't cut down any more or they'll wither

Have a look at this on the Sheffield Made Plants channel on Youtube. He's an expert plant guy.

Nematodes are the only thing that worked for me with fungus gnats. I wish I had just got them first, and not wasted a lot of time on other methods!

Cut down on watering.
Top the soil with grit.
The life cycle is fairly short so that should sort it fairly quickly.

Thank you everyone! @ThomasHardyPerennial nematodes just arrived! Thank you for the tip!
