I can't even walk barefoot in my yard because of this horrid weed that is all over!!!! I'm in South AL (zone 8b) and being a native northerner I have never seen such a thing. It's very low to the ground and if you glance at it you can't really see any briars or anything. But, if you look closely, it seems to have little tiny burrs.... However, when you step on it you get a little tiny piece stick to you with two practically microscopic barbs. I've looked at countless weed pictures online and can't figure this out. Anyone have any idea what it is? And how do I get rid of it???? I tried using weed killer, but that just kills my grass (gotta love southern "grass"). There's no way I can rip out my whole yard (it's huge), but I have to do something because my poor dogs don't even want to go outside anymore. Help! (sorry pics are a little blurry)
