Troublemakers

So as I told you before, we have had some problems with our some of our neighbors in the past. Now we have been having a new problem and I am not sure what to do about it.

Three or four kids that live a couple of houses down have decided that it is fun to mess with us. Mostly they are repeatedly ringing the door bell and then running away when we open the door, but they also have been kicking the courtyard door and opening the back hatch of the car and once put a piece of wood on the handles of our courtyard door, which made it impossible to open.

I tried to confronting them once; when they ran around the corner of the house after ringing the bell, I went the other way and caught them trying to hide behind the wall of one of the other villas. They first claimed that it wasn't them that did it and then that they didn't speak any English (despite knowing enough to understand my first question). Since I am pretty sure I know where they live, my first thought is to go talk to their parents, but some other examples of similar problems do not make this sound encouraging (as well as the strong possibility of the language barrier). Calling the police seems excessive, plus past experience has taught me that trying to explain to the police how to get here would be a problem. I'm tempted to get some water balloons and lie in wait for them on the roof of the house and get them next time they try a ring and run attack.
