Controlling raspberries

[SkunkedAgain]

We've got a raspberry patch on the side of our house that's been productive for years. However, my wife has become upset with how the raspberries are trying to spread into adjacent flower beds. In one particular area, the shoots are coming up after passing under a fence. I was thinking about digging a trench down, cutting any existing roots going under the fence, and then installing a long piece of hard plastic that essentially extends the fence down a foot into the ground.

Does anyone have any experience with battling raspberries?

I am trying to keep mine in a pretty tight area also. The one thing that has worked for me is taking the spade shovel cutting it into the soil a few times during the season. Usually in the spring and again mid-summer. This helps a lot, but will always get a few here and there. When I see the same area keep coming up, I will then dig out the area and find the shoot. The plastic will work for awhile, but the little rascals will find a way around it.
