Dead Rats and Mice at my property

[Peter Pezzano]

I manage a property in Boston and I am having a problem with my neighbors next door! They have been using my trash barrels for their trash and have been making a complete mess of my garbage area. They don't close the bags and there often is food in these bags. My tenant went to take her trash out the other days and said that she saw 10 dead rats that were thrown into the trash barrel! My tenants are pissed and completely horrified, (not to mention they are first time renters) to make things worse. I have contacted the neighbors in the past about throwing their trash out in my barrels and they said they wouldn't do it anymore. Well they obviously are. Who has suggestions on how I can handle this?
