A prank is a fake spider in your mailbox and MAYBE even a daytime ding-dong ditch (even that is stretching it). What you are experiencing is vandalism and harassment. I'd call the police non-emergency number (during the daytime, not when it is happening) and ask what they think you should do.
I also like the idea of speed-dialing the parents when it happens. The problem with that is that you don't know if the parents will care.
That's why at the same time the parents are being called, the spouse would be calling the cops as Junior DelinQuent scuttles away. If Mommy & Daddy Dearest don't care? Well, the cops *will*.
agnes!
We knew who they were (kids in my grade). My mom called the cops numerous times - they did nothing. Never could catch the kids in the act, so there was "nothing they could do". My parents approached the mother of one boy, and she denied everything - it wasn't her son! This went on for YEARS at my house - constant prank calls, ringing the bell, destroying our lawn furniture. The kids were never caught, never paid any price, and basically got away with it scoot free. Trust me, there is no karma in this world, these mean kids basically won every time and never had to own up to it. Just showed me how useless police are with these things.
Let us know what you decide to do and how it goes.
