Oh Yes, my girls call them "Pokies". They just jump up and grab you. Our oldest dog, he runs to the edge of the property and comes hopping back, with pokies in his feet.
Those are often referred to as goats-head, especially in New Mexico, sand spurs is the more common name in Texas. I have gotten out on the lot (pre-drought) with my helper, a propane torch, and a garden hose trying to burn the seed up in the fall. (this is the New Mexico treatment I observed). Next day, all the plants burned, the viable seed was sitting on the ground laughing at me. I don't know what my neighbors thought when I got out my shop vac, rigged for dry, and vacuumed up all the seeds I could find, the ground was just carpeted with them.
I tried the roundup (toxic) the next year, it bombed, and in July of 2009 I started digging, putting plant, seed and all in buckets and in the trash. Fort Worth's landfill must have a lot by now. THEN I learned the water cure, but it hasn't been viable with the drought.
But removing all the seed you can the first thing. I've dragged a throw-away blanket with a brick on it (around 2004 - 2005) etc.
Digging and removal of all plants and seeds remains the best solution I've found.
