So, I had rats in my attic and in the walls of the house.
Had a rat eliminator man round to deal with them. It turns out one has died in the wall on the upstairs landing. The smell is absolutely putrid. Literally vomit inducing rancid. It is the most disgusting smell I have ever smelled and is permeating throughout the entire house.
The rat man said short of pulling down the wall (which I'm not going to do) there's really nothing to do except live with it for 2-3 weeks until the rat has completely decomposed.
I'm keeping all the windows open even though it's freezing. And have ordered some activated charcoal and air fresher.
Has anyone ever encountered this and found a way to manage the smell?!!!
