Anyone know of any good household weed killers? Preferably ones that kill dandelions and their wretched roots. My front lawn is overrun by dandelions (and half-foot tall grass too) and the neighbors are probably going to call city ordinance, or so my mom has heard if we don't cut it soon. But first I suggested that we kill the weeds so we wouldn't have to worry about them spreading when we mow over the grass. I could go to the hardware store and look around, but I'd like just pick one up by recommendation. Any suggestions??
