To kill a berry bush, cut it down and paint full strength Brush B Gone on the stems. Paint neatly, this will kill anything it touches. The only time to kill a berry plant is in the fall when it starts to go dormant. When the leaves begin to yellow, paint away. In the meantime, chop chop chop (but not until after the berries ripen. Yummm...).
PS: I think you have been watching too many late night horror movies. Next it will be popping out of the rose bush stems.
