I will come and dig some out for you if you are local to me (Bristol). You could also sell dormant or potted on clumps on eBay and turn your problem into a money spinner!
To eradicate completely, spray with glyphosate when the plants are in full growth. (Move a clump or two to another bed if you want to keep some).

Hi Timi, they are called Arum lilies, and yes they do multiply readily. They are a classic plant, and in the right position, look lovely along the banks of streams and such. There is no easy answer to being rid of them, but using the variety of methods suggested by other commenters you should have success. People are always on the look-out for plants, so a bit of research might find that whoever wants them will also come and dig them up too!
