Puncture Vine also called "Goat heads" is a frustrating weed. Luckily it is an annual, so if you proper apply a pre-emergent prior to their arrival, you can avoid them. Here is a link to a Plant Talk on Puncture Vine. Follow the link at the bottom of this link for more specific chemical controls. http://www.ext.colostate.edu/ptlk/2109.html
