This is why -

it is such a pest: it crowds out the less competitive native species like hemp-nettle and gypsywort that also like damp areas.

Pull them up...

...if you see them. Does precious little good for native species. Not poisonous so OK to touch.

Uprooting is not the answer!

Unless you ensure that you either hang them over a branch or a fence to desiccate; or crush each stem node (the swollen sections that occur at intervals). Otherwise the plants will re-root from the nodes.
They can also produce cleistogamous flowers (i.e. they self-fertilise in the bud without ever opening and being clearly visible).
We found that goat browsing (a neighbour had a flock) was effective, but of course they eat everything else, too. It helps bring the problem under control, but the seed bank will last for several years.
