Bamboo - I need help?

I have an area about 50 ft x 30 ft and it's completely overrun with bamboo. It is overrunning into my neighbor's yard. I need to get rid of this stuff but nothing works. I can't kill it, poison hasn't worked, nothing is getting rid of this damn bamboo (it was here when I moved in). I talked to a woman at the nursery and asked her how to get rid of it - she said pray.





It didn't work.





Anyone else have any great ideas? Thanks in advance!!

I control mine by cutting the runners about two inches above the leaf bud close to the ground and fill the inside with a 1:1 mix of vegetation killer and water. After it's dead just pull it up it will probably sterilize the area for a year. Try it on the old growth

Reply:Round Up. No need to dilute since you have a bamboo infestation vendetta. Paint on leaves with a paint brush. You'll see results within hours. Then you can cut down, dig out, or burn the offending flora.
Reply:Try using a backhoe and tearing up the area, assuming you don't mind destroying the entire ground area.
