Well after 2-3 days of peaceful sleep in the back of the house away from the stink, the rats go marching on. We have heard more in the walls and across the ceiling of our bedroom. Perhaps they are a bit lighter / younger ones, but I don’t know. Perhaps the dead one in the chimney has decayed enough for the rest to get by and head back up every night. I really don’t know, but I do know that there are more up there. I found a great pest/rat removal company website. Too bad they are in Orlando FL where I used to live instead of here in Melbourne. orlandorats.com
