I got a little creative in my approach.
I had the typical circle, read they were the poisonous variety and wanted them gone. Website suggested using a glove as you extract them, which I did. After which I had, fresh off the stove, big pot of boiling water. Yep...I cooked the spores right in the ground! LOL
I just poured that bubbling water right on top of them. Cooked a small patch of grass also, very minor indeed, but I haven't seen them return
Good luck!
Looking forward to comments on the approach
