Hi Shambo, Yes you can control thistles and yes I can direct you to your nears University of CA cooperative extension ofice and get yourself a permit to buy the chemcials to get rid of the weed. We use Transline Herbicide and it's worked so will that all are neighbors have join in on controlling their's. The stuff is a little pricey, but well worth the cost. It's been two years now since we started spraying and we still get a couple now and then, but we just pull them up before they flower. Anyways good luck and get ahold of your local Agriculture Department, they are always too happy to help.
