I had the same problem with a cabinet outside my house. It is placed on a corner next to a hedge and with the youngsters messing about the hedge had taken a right bashing. The Police did their best to move the youngsters on but they would just come back later and the noise they made late at night was upsetting all the residents.
I remembered I had a bucket of chicken pellet fertiliser which I had tried to use in flower borders near to my house but the smell had made it unusable. It took several applications around the cabinet to have any effect but eventually the youngsters stopped hanging around.
We do have a fine display of weeds though.
