I have a downstairs toilet that protrudes from the side of the house. As a result, it has a loft area that is not accessible without cutting into the plasterboard ceiling.
Mice are fairly common in the area due the woodlands opposite the house, so it wasn't a surprise when I started hearing noises in the space above the toilet. What I have noticed recently are some dark orange spots appearing on the ceiling. Some now have droplets hanging from them.
Could this be decomposing mice in the loft space?
It's worth noting that last year some water damage had occurred which has (hopefully) been fixed.
