See the year and a half old rat-bait, and newspaper with Mogwai piss stain. That worked for about four months.
We know the rat goes exactly there because we hear it walking on the newspaper, and another photo of this area has rat poo on it.
In a way we're lucky I can reach this without climbing in the roof, although I fear the same reason I can reach it is the same reason we get rats in there.
Anyway, this picture, if I were to take it again, would include two new rat-baits. We'll see if that makes any difference when the little bastard comes back tonight.
If I ever build a house, I'm including inner walls that are all actually doors you can open to view your wall cavity...
I need to figure out a way to grab all the old rat stuff from down this hole. It's getting crowded down there. Anyone have a three metre long extendy arm with a camera on the end?
