How do I get rid of them?

Only water the plants from the bottom and they will all die off

They are sciarid flies or fungus gnats. They love damp conditions so easing off the watering can help as can top dressing pots in fine gravel.

The problem is not the flies, it’s that each of those flies has morphed from a larva in the soil which has been busy eating the plant roots. So it’s important to break the cycle

Buy a carnivorous plant

You need Nematodes. They will deal with them! Mix into water, water plants, wait a few days. Job done.

can you recommend a type/source of nematodes please one of my lemon trees is suffering badly and spraying has not fixed it

lochmaree · 16/02/2025 07:56

For my houseplants I gave the pots a gravel topping and then sprinkled diatomaceous earth on the gravel, I only bottom water, and I have a few of the sticky things.

We had the same. I put gravel on top of all the houseplants and they are now all gone.

I found they sorted themselves out when I stopped over watering my plans.

Change their soil, let them dry off for a few days, and cover the soil in cinnamon

I found the same. I bought a moisture monitor sensor of from amazon and keep the soil at the very bottom end of moist and the flies disappeared.

Agree with the nematodes recommended above, bought mine off EBay,

Pashazade · 16/02/2025 08:49

@Breadcat24 It was these from Amazon. Worked a treat.

You need a combination of nematodes (to get the larvae) and yellow sticky traps (to get the adults)

This, cinnamon has sorted mine out completely.
