We had a natural wildflower patch professional sown and had lots of these thistles. Very pretty but now had thistles growing in the middle of the lawn !!! I'm glad the above advise confirms I'm doing the right thing by both digging out and using glyphosate but digging out is telling on my back as there can be twenty little blighters a day

Creeping thistle is my favourite, always reminds me of my mums garden..
The way I control creeping thistle is to fire it when in seed. Only the seeds burn and they do so in a flash. There's hardly any smoke, the thistle itself does not burn because it's wet and if done carefully, there's little likelihood of it spreading to a lower story. You need to be sensible about it and take sensible precautions. In other words don't go and fire a vast swatch beside a barn or something on a warm, breezy September's day.
This controls seed spread as no chemical will ever achieve.Done annually, and you weaken the plant. They'll disappear.
