What are these creatures and how to get rid of them?

[Moh]

Dear all,

It's been a while that these creatures have spread everywhere around my plants. You can see one of them on my flower.
Seemingly, they live the in soil and spread everywhere. I can no longer keep my plants inside my flat because of them.
Can anyone identify them and does anyone know how I can get rid of them?

Thanks,
Moh.

Hard to tell but some type of robber fly (asilidae), perhaps? They are carnivorous and won't hurt your plants, but I wouldn't want them inside my house either!

Not sure how they reproduce, so can't advise on how to get rid of them. If they are breeding in the soil you might need to treat that with something that kills off the eggs and larvae. (And that's just assuming I'm correct about what it actually is.)
