Banning alumni from the house?

[ZZ-kai-]

My chapter just moved into a new house (well, not new, but different). We have a good core group of guys living there. This is a fresh start for them and a chance to leave all our baggage from the last house, there. In the past, we have had some dumbass alumni come back and trash the house, and this happened again this past weekend at the new house. We are looking for solutions to this, other than me throwing them from the porch. (I'm alumn, and yes, I'd make the trip back there to do that).

Question is, have you ever banned an alumni from the house? If so, how did you do this, how did you communicate this and how did you enforce it?

If you have not used 'banning', what did you do to solve the problem?

Any/all help is appreciated.

Thanks.
