Seriously?

I thought about doing this but decided to just let it go most of the time. If I ask them to leave but tell them they can come back after whatever time they will usually respectfully leave and come back. They don't get out of school until close to the end of naptime anyway so it isn't a huge deal. I try to be a little cool about it

Hmm, maybe start keeping a tally - and for every time they ring and run, they need to repay you with doing a chore for you! Something innocuous but tedious, like washing windows or something ... That'll take the fun out of it.

It's been my experience that if you say something to the kids about it, they'll graduate to something worse. They'll eventually stop if they see that it doesn't bother you (even though it clearly does). I've had far worse things happen to the point where I, like Donna, freaked out one day, charged right into the kid's house where his mother was sitting in the kitchen drinking a coke, I grabbed him by his shirt, pinned him up against the wall and said some things that I shouldn't have. (No, no foul language, but I spelled out exactly what would happen to him if he came on my property again for any reason.) I don't know who was more shocked, the kid, his mother, my son or me. Try to let it go.

I'm sadly guilty of dorbell ditching too...we did it to my neghbors grandmother as she was babysitting us while our parents were at work. Sigh, in retrospect it was mean to have her get up and answer the door while we hid in the bushes and laughed...but as a kid it was oh so funny.
I wasn't exactly a nice little kid though, I pulled quite a few pranks. Nothing overtly destructive though
