NZ flatworms - is this a taboo subject?

The flatworms were first reported in Scotland in the 1960s and have spread to all of Scotland and into Northern England.
They don't seem to prey on those little brandling compost worms, or on slugs unfortunately but their sole diet is those lovely fat earthworms.
Here is a picture of a flatworm (to avoid!)

Loads of earthworms here in London - and the red composting worms around tree stumps and in the bins. If there were any risk, I'd be rinsing the roots too - or asking for cuttings and seeds instead.

Those thin red ones are of course young earthworms.

Haven't seen any here, didn't realize they were a problem. It's interesting though, someone has dumped old compost in the field behind our house, obviously from pots and I have been wondering about the spread of disease/pests. It's good that your group are aware of this issue.

I've just googled them. None at all here in my garden, south Wales. We do have loads of those thin red ones though, plus the usual kind!

No flatworms are huge.

Those are almost certainly brandling(sp?) worms that are necessary in the compost heap.

Grammaretto, I’d never heard of these things. Google tells me they eat earthworms. I’ve noticed less earthworms in my garden.
I have the same red worms in my compost. Are they the dreaded NZ flatworms?
